If you own or use a commercial vehicle with a diesel engine, you need to learn about what’s known as diesel exhaust fluid (DEF), an essential part of your vehicle’s exhaust system. Instead of powering your vehicle, the fluid is designed to dissolve harmful gases and chemicals in the exhaus …

The fuel injectors in your diesel engine should last up to 100,000 miles or more. After that, it’s usually only a matter of time before they break down. These crucial components feed high-pressure fuel into the combustion chamber so the engine can generate power. If they get stuck or lose …

If you own a diesel vehicle, you should be familiar with what’s known as the diesel particulate filter, or DPF. Every diesel engine has one to prevent soot and ash from leaking into the exhaust. These particulates reduce air quality and are considered hazardous to those with respiratory co …

The fuel injector pump is a crucial part of your diesel engine. It does exactly what the name implies. It injects fuel into the intake manifold in the vehicle so the engine can generate power. If the pump fails to inject fuel, the engine won’t start. These components are designed to last f …

The EGR cooler is an essential component of any diesel engine. It lowers the temperatures of the exhaust gases as they circulate throughout the engine. The EGR cooler sends coolant to the exhaust gas recirculation system to transfer heat away from the combustion chamber. This is a complex …

It’s well known that diesel engines use a mixture of air and fuel to produce energy. The fuel needs to enter the combustion chamber at just the right time to make sure enough power is generated to make the wheels turn. This can be a surprisingly complicated process filled with many moving parts and …
