How Diesel Is Different

Both diesel and gas engines are internal combustion engines that convert fuel into energy. Combustion allows the engines to work in a series of small explosions, and this is where the two engines differ. Gas engines operate when fuel is mixed with air, then compressed by pistons and ignited by sparks from spark plugs. Diesel engines compress the air before injecting the fuel directly into the combustion chamber. Air heats up when it’s compressed, so the fuel in diesel engines ignites without the use of sparks. Using this form of direct injection, diesel engines are more efficient than gas engines.


Diesel engines run on diesel fuel which, when compared to gasoline, is:

  • Thicker

  • Heavier

  • Slower to evaporate

  • Higher in energy density

These factors allow diesel engines to get better mileage than gas engines. Diesel engines emit very small amounts of greenhouse gases such as carbon monoxide that lead to global, but they emit relatively high amounts of soot and nitrogen compounds that cause acid rain and other issues.

Uses for Diesel Engines

Diesel engines are built ruggedly to withstand the rigors of high compression. They are more efficient than gas engines and they can work for much longer before needing repairs. Diesel engines also provide more torque to the driveshaft of your vehicle, which allows cars to … Because of their efficiency and fuel economy, diesel engines are used in a wide variety of vehicles and machinery, including:

  • Freight trucks

  • Boats

  • School buses

  • City buses

  • Trains

  • Cranes

  • Farming equipment

  • Emergency response vehicles

  • Power generators

  • Pickup trucks

If gas engines are fast-working like race horses, then diesel engines are stronger and more enduring like workhorses, making them perfect for use in work trucks and heavy-duty equipment.
