3 Performance Advantages of Diesel Engines

3 Performance Advantages of Diesel EnginesCompared to gas engines, diesel motors are far less mainstream, mostly appearing under the hoods of work trucks and heavy-duty equipment. But as automakers more readily realize the performance advantages of diesel engines and continue to advance fuel technology, diesel doesn’t show any signs of slowing down.

Interested in which areas diesel rides beat out gas? ATC’s diesel gurus will walk you through 3 performance advantages that diesel engines provide below.

1. Through-the-Roof Fuel Efficiency

Likely the number 1 benefit that a diesel engine delivers is enhanced fuel efficiency. As a fuel source, diesel can produce more power per unit compared to gasoline (14% more energy by volume, according to a Q and A with GM’s director of global advanced engineering).

This, in addition to other engine treatments, such as turbocharging or advanced fuel injection, allow diesel engines to reach mpg estimates that tower high above their gas-driven counterparts.

2. Torque Is a Diesel Engine’s 1, 2 Punch

In terms of how a diesel vehicle feels to drive with your foot on the pedal, the first thing most people notice is the abundance of low-end power (or torque) that’s on tap. Torque translates its power talents in the form of immediate acceleration off the line and greater hauling power when towing.

The feeling of drawing power from a larger engine under foot and the instant zip up to speed after pausing at a stop sign or traffic light appeals to many consumers while being able to boost payload and towing capabilities is a leading reason why diesel engines dominate truck manufacturer’s model lineups.

3. Longer Engine Life Span

Within a diesel engine, instead of igniting a spark plug to get the engine to burn fuel, compressed hot air sets off processes within the engine chamber. Spark plugs are one of the most replaced engine parts in gasoline vehicles, and when they go, they usually don’t go quietly. Removing them from the equation entirely makes diesel engines more reliable in the long run. It also means they’ll require less maintenance along the way.

Plus, to stand up to the extreme pressure levels that occur during combustion, diesel engines are built extra robustly. Let’s just say, if a diesel engine and a gas engine got into a fight, we’d expect the diesel engine to be the heavyweight champ.

Do the Unthinkable with Your Diesel Engine

Durable, heavy duty, and highly efficient, to car and truck lovers, a diesel engine’s performance edge never ceases to amaze.

    It is interesting that diesel is so much more efficient than gasoline. This is something that I have never realized because diesel usually goes into bigger vehicles, and they tend to be less efficient. Is it difficult to find a great diesel mechanic? This would be one of my main concerns, because if I can’t find a mechanic then there is a lot of pressure for me to not ever mess up. Thank you!
