why a diesel engine is so much more powerful than an gas engine.
In: Engineering
So, this is partly right. A diesel engine typically produces far more torque (twisting power) than a gasoline engine because diesel is more dense than gasoline (it is literally heavier) so each explosion creates more power. Thing is, the motor doesn’t turn very fast. As a result almost all diesel engines have some sort of forced induction, like a turbocharger which help with horespower tremendously. Horsepower is torque times engine RPM times 5252. So if you get all of your torque at 2,000 RPM, you have a lot more power than a gasoline engine at the same RPM but the motor will not be able to rev as high. The turbo helps with that but you will still notice diesels have a lower red-line than gasoline engines.
