Many people think of massive, loud trucks when they think of diesel engines. However, these systems are often misunderstood even though they offer lots of benefits. If you have a diesel truck are thinking about purchasing one, here are the answers to several frequently asked questions to help you take care of your vehicle and its engine. 

4 Frequently Asked Questions About Diesel Engines

What is diesel fuel?

It’s a complex mixture made from crude oil through a process called fractional distillation, which separates different parts of oil. Though you can find it at gas stations, it’s thicker than gasoline and has a distinct smell. It’s used to fuel diesel trucks as well as home heating systems. 

Are diesel engines different from gas-powered engines?

Like a gasoline-powered vehicle, diesel engines operate using an internal combustion system. However, diesel trucks function by using a compression-ignited injection system that injects fuel into the combustion chamber where it is ignited by high temperatures achieved by compressing the gas pedal. The heat produced with diesel engines translates to better thermal efficiency over gas, which increases its fuel economy by roughly 20%.

Are diesel engines noisy?

Though these engines used to be loud, these days, they are built to be quieter on the road. The noise, which resembles a rumble or rattle, occurs because of how the fuel ignites. Once it’s mixed with air and compressed by the piston, the extreme heat produces a spontaneous ignition that creates an increase in pressure. Advancements in injection timing, electronic controls, and updates to the combustion chamber help the fuel enter the combustion chamber in a series of smaller doses to reduce the increased pressure and soften the noise. 

What are the benefits of diesel-fueled vehicles?

Diesel engines don’t require a lot of fuel to generate substantial power, which makes them more fuel-efficient than gas truck’s. The fuel also gives the vehicle more torque, so it feels sturdy, even at slow speeds. Manufacturers have to abide by the same EPA regulations for gas cars, so newer diesel-powered vehicles produce few emissions.
