Diesel Engines

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.

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.

How Many Volts to Start a Diesel Engine

It’s winter time, and that may mean your battery is on its last legs. If you’re shopping for a new battery for your diesel, you may be wondering how many volts it takes to start a diesel engine. 

Read our guide on everything you need to know about diesel batteries, and how many volts it takes to start a diesel engine.

How Many Volts for a Diesel Engine Battery

The best diesel engine batteries are 12 volt batteries. When starting a diesel engine, it is typical for a battery to have less than 12 volts, but then get up to closer to 14 volts and above when the engine has warmed. Diesel engines require a 12 volt starter that is able to spontaneously combust and get the engine running. That’s why even though diesel engines require 12 volt starters, they run on two 12 volt batteries that work in tandem to ensure that the starter has the juice to get the engine running. 

Can You Run a Diesel with One Battery

Most diesel engines have two batteries that are connected in parallel. Even though you need 12 volts to start a diesel engine and each diesel battery would be a 12 volt battery, it’s not recommended to run a diesel on a single battery. This is because along with needing voltage to start, diesel engines require a higher cranking amperage than gas powered engines. So although you can definitely start a diesel engine with a single 12 volt battery, you won’t be able to run the engine effectively for very long. 

Furthermore, if one of your batteries dies, it’s important to replace both. When batteries are running in parallel, it’s important that they are the same age, type, and size. This is because the size, type, and age of a battery all relate to its amperage and how current will be distributed through the engine. If the batteries aren’t working the same, it can cause issues with your engine.

Difference Between Voltage and Amperage

Volts and amperes are completely different measurements regarding electricity. A volt is a unit of electrical potential, or the size of force that would send electrons through a circuit. Amperes, on the other hand, measure electrical current and how many electrons are flowing through a circuit. Regarding diesel engines, the battery voltage is the amount of force it takes to get the engine started, whereas amperes are how much electricity is flowing through the engine when it’s running. 

Best Diesel Engine Batteries

There are plenty of diesel batteries to choose from, so we’ve compiled a list of three diesel engines that we would recommend. 

1. XS Power D3400 XS Series 12V AGM High Output Battery

xs power

This battery has a tight seal and fiberglass layers to prevent spilling and limit vibration. This battery is also incredibly powerful in the cold, making it a great choice for climates with long winters like Alberta. It can deliver steady power in frigid temperatures as well as has a fast recharge time, making it a great choice for your diesel.

2. ACDelco 94RAGM Professional AGM Automotive BCI Group 94R Battery

ad delco

This battery contains high-density negative paste to increase performance as well as the batteries overall lifespan. Its vent cap design reduces acid leakage risk, and it runs great in the cold weather with 800 cold cranking amperage. With solid specs and efficient performance, it’s an ideal choice for many diesel owners. 

3. Optima Batteries 8004-003 34/78 RedTop Starting Battery

optima red

Optima batteries are a fantastic choice, and the RedTop ensures 800 cold cranking amps for those frigid winter mornings, plus it has a strong casing that gives the battery more resistance to vibration, making it incredibly durable. You can definitely trust that this battery will do its job with your diesel.

How to Start a Diesel Truck in the Cold

It’s official, winter is here and that means our diesel trucks are out there in the cold. It’s important to start your diesel truck in the cold properly to avoid any damage. Cold temperatures can cause issues with engine oil, diesel fuel, ignition, and battery power. 

Why are Diesel Engines Hard to Start in the Winter?

Diesel engines are typically more difficult to start in the winter than gas powered engines. This is because they require high temperatures created by compression to ignite the diesel fuel. Below -15°C, it’s five times more difficult to start a diesel engine than it is at 25°C. Along with the actual temperatures needed for ignition, diesel fuel is also more difficult to ignite at cold temperatures because it has gelling properties After about -9°C, diesel fuel can start to gel. This can cause a variety of issues from forming wax crystals to plugging the fuel filter. 

8 Tips to Starting a Diesel Truck in the Winter

One of the most important tips to getting your diesel started safely in the winter is to prepare and know what to do when temperatures drop.

1. Use a block heater

Block heaters help diesel engines start on cold days by heating the internal combustion chamber. The block heater heats the coolant to circulate through the block and engine, keeping it warmer and making it easier to start.

2. Use a winter fuel

There are different grades of diesel fuel – Diesel #1D and Diesel #2D. Most people use Diesel #2D throughout the year as #1D is thinner and more volatile; however, blending the two can help ensure that the diesel fuel doesn’t gel as easily. 

3. Use Winter Fuel Additives

Winter fuel additives are an important addition when temperatures drop significantly. A winter diesel fuel supplement can prevent fuel gelling, boost cetane for faster cold starts, and keep injectors clean. However, if you are using a mixed, winter fuel, be careful with fuel additives and don’t double up on winterizing your fuel. 

4. Switch to a lighter weight engine

You can’t use the same engine oil in the summer and winter as thicker oils will not lubricate the engine as adequately when it gets cold. Be sure to check the recommended engine oil ratings of your diesel model to ensure that the winter engine oil you use isn’t too light for when the engine warms up. 

5. Change your fuel filter

If you are worried your diesel fuel has gelled, it’s time to change out the fuel filter. Gelled diesel fuel can seriously clog your filter and cause a lot of damage to your engine. Replacing a fuel filter is far less expensive than replacing an engine!

6. Allow for adequate warm-up time

When it comes to diesel engines, it’s a good idea to let your truck warm up for a minimum of 5 minutes before driving. The colder it is, the longer you should let it warm up. By allowing your diesel truck to idle you can warm up the oil temperature enough for adequate lubrication of all the hard internal parts. 

7. Replace your batteries as needed

If you have batteries that are over 10 years old, it’s probably time to replace them. Another sign it’s time to replace the batteries is if you’re struggling to start your truck in warmer weather. If you need to work on getting the diesel started when it’s about 0°C, then be sure to replace your batteries before the temperatures drop. Batteries lose 60% of their capacity when it’s below -15°C, so ensure you have batteries that can keep up with the cold!

8. Keep your fuel tank full

A full tank is less likely to develop any condensation that could freeze and cause the fuel to gel. Filling your tank more often will help your diesel run a lot better in the wintertime. 

Winter can cause a lot of issues for diesel engines, but by following these tips and performing any needed winter maintenance, you can help your diesel truck start a lot better when temperatures drop!
