Diesel Engines

What are the Benefits of Remanufactured Diesel Engines and Custom Parts?

What do you want to get out of your diesel engine? From serving as the workhorse that keeps you on the go for work to understanding the power of a diesel engine, your vehicle has more value to you than just acting as a piece of equipment. Just as you are looking for quality workmanship, we are committed to bringing you the best of the best when it comes to remanufactured engines. There are many hidden benefits to remanufactured engines that can be lost in translation, and we want to be clear and upfront about what makes us so passionate about providing quality services and products to our customers.

What makes remanufactured engines different from rebuilt engines?

First things first, a remanufactured engine and rebuilt engines should not be framed as the same type of engine. A rebuilt engine is one made up of reconditioned parts or new parts, but they do not go through the same quality and performance testing or inspections. Rather, rebuilt engines can use new or used parts at a cheaper price than a remanufactured engine.

Alternatively, a remanufactured engine is made to the original specifications and extra time and care is taken to disassemble, inspect, machine and reassemble the engine to ensure that every component is held to the highest standard of quality. In reality, it is on the same playing field as a new engine, but with a greater emphasis on sustainability.

Want to take a closer look at engine types? Check out our previous blog for a breakdown of rebuilt, remanufactured, and refurbished engines.

Why should I choose a remanufactured engine?

Choosing to upgrade your engine doesn’t always have to be a worst-case-scenario response to a failed engine. Whether you are starting to research the next steps or you want to upgrade your driving experience, a remanufactured engine has many unspoken benefits.

Reliability and Durability

Unlike the stigma surrounding used engines, remanufactured engines and their inspection process bring the machine shop to the next level. Every part and mechanism has been cleaned, undergone thorough inspection and certification, or has been replaced if there are any signs of wear and tear. The expression “good as new” is not an understatement, our remanufactured engines are built to last and withstand the lifespan of the parts. Not only that but they are tested and designed to give you reliable, consistent performance on the road.

Reduced Environmental Impact

The last few years have shown the impact that resource shortages can have on the auto industry and repairs. When you choose to work with an engine remanufacturer, every deliverable piece is already on hand in the warehouse or can be machined on-site, thereby reducing wait times and shipping costs and lowering our environmental impacts. We work with a variety of suppliers to continue to bring you the best parts and customized solutions for your engine. By keeping everything in-house, we are lowering the amount of energy spent on machining processes.

Customization

Our crate engines, designed in-house, can be made to order with customized solutions. After many years of testing and working in collaboration with Speed of Air Technologies, one of the top recommended customized solutions for 2023 is the addition of the Speed of Air Hyperformance Pistons. The Speed of Air line of remanufactured engines is the first in North America to feature this technology, bringing you reduced emissions, increased fuel efficiency and overall performance for your vehicle. You have the freedom to choose what you would like for aftermarket parts for engines.

Are remanufactured engines covered under warranty?

Choose wisely: Why are diesel engines more efficient than gasoline engines?

How well do you know your engine? As we enter into summer, it could be time for a change for your engine. Whether you’re looking for ways to improve your medium-duty diesel engine or a replacement for work, DFC Diesel offers a wide selection of crate engines and parts to fit your needs. This year, we are excited to provide our Speed of Air crate engine series featuring the Speed of Air Hyperformance pistons. This state-of-the-art technology can save you time and money by extending the life of your diesel engine and increasing your fuel efficiency. 

It’s time to debunk some myths surrounding diesel engines. Are you ready?

Diesel versus gasoline: Which engine has a longer lifespan?

At face value, the price tag of a diesel engine can be off putting, but the return on investment is higher than with a gasoline engine. With technological advancements and new designs, the average diesel engine will surpass 800,000 km (500,000 mi) compared to the average of 320,000 km (200,000 mi) for gasoline engines. Diesel engines are the powerhouse for work trucks, offering you greater load capacities and towing capacity compared to gasoline. 

There are three aspects of a diesel engine that lengthen its lifespan. First, the engine design improves its overall performance. They are designed to withstand a higher compression ratio and cylinder pressure. The powerful nature of the compression chambers and high heat requires high-quality internal parts, meaning that diesel engines house larger and sturdier bolts compatible with larger crankshafts and camshafts. Overall, they offer better engine lubrication to keep it functioning as it should. For more information on the benefits of your engine, check out our previous blog post to find out which engine design gets the best fuel mileage.

The second aspect is diesel fuel. The price difference at the pumps for diesel and gasoline fuel is reflected in the different chemical makeups. Gasoline fuel is an aromatic hydrocarbon, making it harsh and corrosive to your engine over time. Alternatively, diesel fuel is made from crude oil and allows your engine to burn the fuel slower than gasoline as a result of a smaller air-to-fuel ratio. The slower burn rate is reflected in slower cylinder wear and tear compared to a gasoline engine.

Finally, the last aspect of a diesel engine’s lifespan is the lower RPMs. The power of a diesel engine comes from the higher torque in the engine compared to gasoline. Through requiring less power, there is less wear and tear on each of the engine parts, namely the pistons, rings, cylinder walls, bearings and valves. Regardless of your relationship with your mechanic, fewer trips to the shop for maintenance make diesel engines a more attractive option.

At DFC Diesel, our remanufactured engines are designed to withstand tough working conditions that you may encounter. We partnered with Speed of Air Technologies to test the Hyperformance Pistons and see the results for ourselves. The dimpled effect of the pistons allows for less carbon build-up inside the combustion chamber, giving you more power and a longer lasting engine.

What makes a diesel engine more fuel efficient?

When measuring fuel efficiency, a good indicator of fuel savings is how your engine and vehicle performs under load. For hauling and towing, diesel engines can outperform gasoline engines while under load and last three times longer. The fuel efficiency of a diesel engine is a result of the longer strokes of the engine. There is more time for the piston to move away from the heat, lengthening its lifespan and building up the power in the engine. Due to the high heat in the chamber, diesel engines require high-quality parts, and pistons are part of the puzzle as they are designed to withstand countless heat cycles without crumbling. To reduce heat transfer, pistons are coated with a protective thermal barrier coating.

Why are maintenance and high-quality parts important for a diesel engine?

When you care for your engine, your engine will care for you by saving you money time and time again. At DFC Diesel, there is no doubt that we love diesel engines and the potential they hold. Built for reliability, durability and longevity, when you take time to properly care for your vehicle, you will save money every year. Regular maintenance and investing in quality parts and service will help save costs for replacement parts and oil changes.

How will Speed of Air Hyperformance Pistons improve my fuel economy?

With long hours on the go, hauling supplies and ensuring your gear is ready to go, ensuring your engine is ready for anything is our top priority. Diesel engines are powerhouses, but even with the best care they can start to break down over time. Speed of Air’s Hyperformance Piston is designed with you in mind to give your engine a longer-lasting life and save you money to invest back into your work.

The 3 most common pitfalls for fuel efficiency in diesel engines

Diesel engines are known for their consistency, and that can extend to common troubles that people encounter over time that can dramatically impact fuel efficiency. The three most common pitfalls include carbon deposits, glow plug replacements, and engine oil oxidation. 

Carbon deposits, or carbon build-up, take first place for being one of the most common causes of decreased fuel efficiency in diesel engines. Due to the high temperatures within the combustion chamber, carbon soot can form within the chamber and around the piston and injectors over time, preventing it from reaching the necessary temperature. 

In diesel engines, glow plugs are heating elements used to preheat the air in the combustion chamber before the engine starts, allowing the fuel to ignite faster for a smoother start. Along with improved cold weather starts, glow plugs can improve combustion efficiency, but they are designed with a limited lifespan due to corrosion and increased wear and tear from high temperatures. For more information on glow plugs, check out our previous blog post.

The last common pitfall is engine oil oxidation, which can cause the formation of deposits or sludge, increased oil degradation and decreased fuel efficiency. Like each of the other issues we have covered, this cannot be avoided but the use of engine oil additives can greatly improve the oil quality.

What makes the Hyperperformance Pistons more fuel efficient?

The unique design of Speed of Air’s Hyperformance Pistons was made with customers in mind by focusing on the challenge of carbon build-up within the chamber. In testing, flow bench techniques revealed the fuel wash areas on a typical diesel engine piston crown to determine where carbon is most likely to build up. The turbulators, or dimple effect, are optimized for medium-duty vehicles with Powerstroke, Duramax, and Cummins engine pistons.

So how does it work? 

The turbulent layers and surfaces allow for the flames within the chamber to burn closer to the cool metal surface of the combustion chamber wall, thereby making it difficult for carbon to form with each use. Each Hyperformance Piston is crafted with a thermal barrier and anti-friction coating on the crowns and skirts of the piston, which help to keep the heat in the combustion process while minimizing resistance. The result means more power within your engine and greater fuel efficiency.

At DFC Diesel, we are committed to offering high-quality products and services to ensure you are getting the best quality engine for your money. For two years, we have been independent testers of Speed of Air Technologies with over a dozen models found in Dodge, Ford, and Chevy trucks. As of 2023, we now offer a full range of Speed of Air remanufactured engines.

Under work conditions, our real-life testing of Speed of Air Hyperformance Pistons found that they offer: 

  • 20% or more fuel consumption reductions based on your engine tuning
  • Reduced engine maintenance
  • Reduced emissions ranging from 20 – 80%
  • Smoother running engines
  • Reduced operating costs
  • Increased power

What are the benefits for commercial diesel trucks?

Finding ways to keep your operating costs low can be a challenge, but it is possible. We have found that Speed of Air Hyperformance Pistons can help you to reduce your overall fuel expenses, while also staying with safety regulations. With after-gas modifications factored in, they can also help to stay within your emissions requirements across Canada and the United States.

How do I calculate my fuel savings?

On average, there are more than 20% for fuel savings with a Speed of Air remanufactured engine, but it can vary. Determining your fuel savings can depend on several factors including:

  • Vehicle maintenance
  • Engine application
  • Altitude and temperature
  • Idle time
  • Driver habits

As a side note, when compared to gasoline engines, diesel engines operate with greater fuel efficiency at higher altitudes because they do not have a throttle.

Interested in what you could save? For our calculations, we compared the saves for 100,000 km based off oil change extensions of 50%

  • Under normal usage, with oil changes every 10,000 km: $5450
  • Under moderate usage, with oil changes every 7,500 km: $5700
  • Under heavy usage, with oil changes every 5,000 km: $6200

Will I improve my oil change intervals with Speed of Air technology?

Your truck can be your livelihood, but pushing your engine with long hours and heavy hauls can have severe impacts on your engine life. In 1952, the average new gas vehicle could go 500 miles (804 km) between oil changes. Thanks to modern technology and new gas engines, using products like full synthetic oil, an oil change interval can now go for as long as 25,000 miles or 40,000 km before wear and tear are noticeable. Frequent oil changes can be costly for your vehicle as you lose time on mechanical repairs and spend hundreds of dollars on oil.

Oil change intervals are an essential aspect of vehicle maintenance. Whether it’s the synthetic oil change interval, or a more specific full synthetic oil change interval, or even the synthetic blend oil change interval, it’s crucial to know what’s best for your vehicle. For instance, Ford’s recommended oil change intervals provide a great guideline for many Powerstroke engine owners. For oil recommendations for your specific engine, check out our previous blog post.

Your medium duty diesel engine holds more potential with new product designs and optimized crate engines. We have run a series of tests on engine performance with Speed of Air Hyperformance Pistons, and we have found that they are reducing oil change intervals on average by 50% or more!

Factors impacting oil change intervals

No one knows your engine and how your truck drives better than you, and every vehicle’s oil life can vary. Based on the industry standard, the average oil drain interval is around 5,000 miles (10,000 km), but individual factors can change your intervals. 

Engine design, age and condition

Within your engine, the combustion efficiency can improve your overall engine life, but carbon deposits are a major player for contaminants. When hydrocarbons are not fully burned during the combustion process, they can escape the combustion chamber and make their way into other parts of your engine. Your engine design and condition can depend on the sealing efficiency of the pistons rings, regulated temperature control, and emissions. Every engine is designed with an expected total operating hours and mileage, but good filtration and sealing can help to prolong your engine.

Driving patterns and conditions

What kind of road and temperature conditions do you work within? If you are constantly driving in extreme temperatures on both sides of the spectrum, it can impact your engine oil. Continued cold starting can result in oil thickening, which can impair lubrication for bearings and cylinders. If you drive regularly on steep roads, with high loads and many stop-and-go instances, it can lower your fuel efficiency as your engine oil is working harder. Dusty roads or areas with high humidity can also increase airborne contaminants getting in your engine oil.

Oil properties

Your oil properties are related to the oil quality and formula performance. When it comes to contaminants, some that we look for in your engine oil include:

  • Sludge and soot
  • Water and coolant ingression
  • Fuel dilution

If you are looking for a specific recommendation for your engine based on your line of work and driving conditions, our team at DFC Diesel is here to help to keep your engine operating as it should.

How Speed of Air Hyperformance Pistons are improving fuel economy and emission rates for diesel engines

For twenty years, Speed of Air Engine Technologies has been creating solutions to decrease emissions and increase fuel efficiency by improving the fuel combustion process within internal combustion (ICE) engines. Compatible with Cummins, Powerstroke, and Duramax engines, they have introduced a new piston technology to optimize your engine’s performance, longevity and efficiency.

At DFC Diesel, we are proud to partner with Speed of Air in developing a crate engine for medium-duty diesel applications that have been tested with incredible game-changing results for your engine.

What makes the Speed of Air pistons unique?

Speed of Air Hyperformance Pistons seeks to address the number one issue with diesel engines: combustion. With their new patented design, the pistons have a dimple effect called turbulators across the surface of the piston with varying sizes that are reminiscent of a golf ball design. The design has more than just a visual effect though, as these turbulators create adhesion for the flame and allow for a longer burn time. The dimpled surface can also be applied to the intake manifold and turbocharger compressor blades. Unlike a normal flat-surfaced piston, the jagged edges of a piston make the surface unstable, which can create increased emissions and more fuel consumption.

Through using a combination of specialized metal coating to control the combustion chamber temperature, the heat generated by the piston can be harnessed from the engine and enhance the air-fuel mixture. The result? Over time, you will see fewer carbon deposits form in the chamber for longer-lasting engine life.

What value do they have for you?

Each Hyperformance Piston is custom-made and follows a strict quality control process to ensure they are industry safe for your vehicle. Speed of Air Technologies are manufactured to work for every consumer, industrial engine, and fuel type. When you order a DFC Diesel engine with Speed of Air  Hyperformance Pistons you are getting the only piston in the world that pays for itself.

So what does this mean for your engine? Through real-life testing on engines in a work setting, we have found that Speed of Air Hyperformance Pistons offer:

  • Reduced engine maintenance 
  • Reduced oil change intervals by 50%
  • Better fuel economy by 20%+ greater efficiency can be experienced through emissions-compliant tuning for fuel efficiency
  • Reduced emissions ranging from 20 – 80%
  • Smoother running engines
  • Reduced operating costs
  • Increased power

Investing in your engine can have its perks. You can save $20,000 to $60,000 on your purchase of a Speed of Air Hyperformance piston-equipped DFC Diesel engine.

Do Diesel Engines Have Spark Plugs?

Diesel engines have a unique ignition process where they don’t have spark plugs. In this blog we’ll cover what spark plugs and glow plugs are, the benefits and disadvantages of the two ignition types, and more!

What are Spark Plugs?

In a gasoline engine, spark plugs provide the spark that ignites the fuel-air mixture in the combustion chamber. This spark is created by an electrical current passing through the spark plug, which generates a spark that jumps across a small gap between the electrodes. The spark occurs when the piston is in the ideal position and the mixture is at the right pressure, and this helps to ensure the most efficient combustion possible.

Why Don’t Diesel Engines Have Spark Plugs?

Diesel engines don’t rely on spark plugs to ignite the fuel. Instead, they use a process called compression ignition. This means that the fuel is injected into the combustion chamber while the air is being compressed. As the air is compressed, it heats up, and when the fuel is injected, it combusts spontaneously, creating the power needed to move the pistons. This is why diesel engines are often referred to as compression-ignition engines.

What are Glow Plugs?

Glow plugs are heating elements that are used to preheat the air in the combustion chamber before the engine starts. This makes it easier for the fuel to ignite, and helps the engine start more quickly and smoothly. Glow plugs are typically used in diesel engines that are designed for use in colder climates, and they can be found in a variety of vehicles. So, while diesel engines do not use spark plugs, they do use glow plugs.

What is the Difference Between Spark Plugs and Glow Plugs?

The main difference between spark plugs and glow plugs is that spark plugs are used to ignite the fuel-air mixture in gasoline engines, while glow plugs are used to preheat the air for ignition in diesel engines. Both play an important role in ensuring that engines start and run smoothly, and both have their own unique set of pros and cons.

Benefits of Spark Plugs

There are several benefits to spark plugs, spark plugs have a high energy output, so they are able to produce a high-energy spark that is necessary to ignite the fuel-air mixture in the combustion chamber, which ensures efficient combustion and smooth engine operation. Second, they are easy to replace. Spark plugs are relatively easy to replace and can be done by most vehicle owners with basic tools. They are also widely available and can be purchased at most auto parts stores. Finally, spark plugs are relatively low maintenance. They typically have a long lifespan and require minimal maintenance, making them a cost-effective option for vehicle owners.

Disadvantages of Spark Plugs

Spark plugs also have a few disadvantages to their use. They need to be replaced periodically. Spark plugs need to be replaced at regular intervals, every 30,000 miles (48,280 km), approximately. Spark plugs can also fail if they get dirty or worn. They can become dirty or worn over time, which can cause them to fail and negatively impact engine performance. They can also be affected by heat, this might cause them to wear out faster in high-performance engines or in vehicles that are driven in hot climates. Replacing spark plugs can also be expensive. Some high-performance spark plugs can be very costly and may require a higher level of technical knowledge to install.

Benefits of Glow Plugs

Glow plugs offer several benefits for their ignition power. They have improved cold weather starting, which means that the diesel engine will start more quickly and with less cranking. Glow plugs have increased fuel efficiency. They improve combustion efficiency by heating the air in the chamber to help vaporize fuel more efficiently. This leads to less fuel consumption and lower emissions. Reduced emissions is also a benefit of its own, glow plugs help to reduce emissions by improving combustion efficiency and reducing unburnt fuel.

Disadvantages of Glow Plugs

Glow plugs do feature some disadvantages. They have a limited lifespan, so they will eventually need to be replaced. This can be caused by regular use and tear, corrosion, or exposure to high temperatures. The frequency of replacement will vary depending on the vehicle and driving conditions. If you have malfunctioning glow plugs, it can be expensive to replace them. Depending on the vehicle, the cost of replacement can range from a few hundred to several thousand dollars. This can be a significant expense for some vehicle owners. Finally, glow plug diagnosis and repair can be costly. This is because the system is complex and often requires specialized tools and knowledge to remedy effectively.

While spark plugs and glow plugs both play an important role in ensuring engines start and work to the best of their ability. They are used in different types of engines with similar pros and cons. It’s important for vehicle owners to understand the difference and to keep them in good working condition to ensure the engine runs effectively.
