5 Tips to Improve Fuel Consumption in Heavy Diesel Engines

5 Tips to Improve Fuel Consumption in Heavy Diesel Engines

Posted on

Fuel consumption is an essential part of the proper function of your engine. However, you need to be concerned if you notice an increase in its consumption. Sometimes it is easy to isolate and point out the culprit. Your engine has a moving piston and a fixed cylinder to burn fuel, and you need fuel, oxygen, and heat for combustion.

Here are the mechanisms: The piston compresses the blend of fuel and air. Then, when you ignite the engine, the temperature produces the necessary heat to start and continues the combustion process. During fuel combustion, your engine typically uses fuel injectors and air cleaner elements.

Suppose your fuel injectors are dirty and there is an issue with the air cleaner element. In that case, you experience an increase in fuel consumption. It is vital to understand such details because it sensitizes you to your fuel economy. When you delay service for your heavy diesel engine or use poor quality services, fuel consumption increases. Delayed service translates to clogged air elements. Your best practices on fuel economy include regularly servicing your engine.

As you can see, numerous reasons cause high fuel consumption. And, the ones as mentioned earlier are hardly exhaustive. You realize that aside from your fuel economy, it is essential to remain sensitive to greenhouse gas emissions. Naturally, the reduction of fuel consumption is not a simple matter: But here are five tips to guide you.

1. Use proper Diesel Engine After Treatment Systems

A Diesel Particular Filter (DPF) is a good choice. However, when it fills, you have accumulated soot. It would be best if you had this removed. Introducing high heat into the exhaust system does the trick. It would be best to remember that your active onboard systems use more fuel to burn to heat the PDF. When this cycle is repeated, there usually is a buildup of back pressure in your exhaust system. It increases your fuel consumption, and your system emits high levels of carbon dioxide.

Your best option is to choose an after-treatment system that uses higher injection pressure. Because it reduces both your fuel consumption and the engine's out, that is particular diesel matter (PM). You associate the black smoke (PM) with traditional diesel engines.

2. Fuel Quality

If you are reading this, you know that diesel engines guzzle a lot of fuel, more so the heavy type. Do not attempt to use an alternative way to cut costs. Avoid compromising on the quality of fuel. Cheap fuel will cost you.

Here is what happens with cheap fuel. You interfere with the motion of the engine pistons. Your engine needs a specific viscosity grade. Quality fuel has additives that clean the injector nozzles in your engine, reducing the accumulation of waste deposits.

Manufacturers of diesel engines suggest the appropriate fuel for diesel engines. They have expertise in the functions of engine technology. They understand complex matters concerning fuel quality and its parameters such as sulfur density, oxygenates, aromatics, etc.

You need not worry about such a matter. Leave that to the diesel automakers. In short, keep to the instruction of your specified fuel quality. Good quality fuel helps your engine enjoy a smoother, cleaner experience. Please do not compromise on this. Once again, low-quality fuel also increases your engine's PM.

3. Speed

Improve your fuel consumption: you need to observe your driving style. When you handle a powerful machine, it is tempting to use a heavy foot on the accelerator. As exciting as this is, it will cost you in terms of fuel. When you accelerate abruptly or brake too often, you increase your fuel consumption. You work your engine harder than necessary, increasing its wear and tear. In short, there are times to dry faster, but other times it worsens your fuel economy.

Also, when you change gears, try not to rev your engine because you use more fuel. Try easing your foot off that pedal. You may be aware that using a lower gear than needed affects your fuel economy negatively. Try to put this into practice. When you drive up a hill or negotiate a corner, avoid using high gears. It causes the engine unnecessary stress. Once again, it increases your fuel consumption.

Instead, you may want to adopt a calculated drive style and watch the terrain. You are safer, it saves you on fuel, and it is suitable for a "healthy" engine.

4. Wheel Alignment and Pressure

Yes, it sounds almost petty, but you will be surprised at tires affects your engine's fuel consumption. Experts insist that as your tires wear out, they lose grip or traction. It affects your fuel consumption.

Poorly inflated tires lack the appropriate pressure to sustain the vehicle's weight, let alone other functions. Tires are responsible for the tread on the road. Low pressure causes an increase in the rubber that holds you back as you drive. Inappropriate pressure in your tires causes your engine to labor more, and it worsens with distance coverage.

Check your tires and do due diligence to maintain optima pressure, do this regularly. Tire manufacturing companies recommend that you use the highest pressure possible. If you check the operating manual, you will find the exact proportions suggested. Taking care of your tires extends the life span and reduces fuel consumption.

5. Air Conditioning

On those hot blistering days, you turn on the air conditioner without a blink. It is a reflex action. However, the cooling and fluctuation in airflow take a drain on your engine. Try keeping the fan on cold. You do not need to use the air conditioner. Your engine uses less power, and you save on your fuel consumption.


To improve your engine's fuel consumption, you need to takes personal responsibility. You need not get into detail, but it pays to know some basics. It also pays to understand subjects such as treatment systems and PM matter. Then, you can make informed decisions on your fuel quality, driving style, and habits. Prudent fuel economy saves you money and helps maintain a healthy ecosystem.
