Diesel engines have governors to regulate speed with respect to the load on the engine. Which device performs the same task in the case of gas engines?
Gasoline and diesel engines are quite different because they tend to differ in the range of rpm’s that they produce power. On a diesel, a governor is desireable in that the power band is quite narrow and the gearing is such, that without a governor the operator would have to adjust the throttle more often than what you would consider “normal”. Gas engines have a broader range of power and does not drop rpms as much as a percentage of this range due to its nature. Therefore gas engines do not need a secondary device to do this. However, if you’ve ever driven a gasoline powered car up and down mountains, you realize that you have to compensate for engine load as the car goes up or down a hill. Almost no gasoline powered cars have governors to assist in adjusting engine speed as compensation for the drivers input via the gas pedal. However, many small engines like used on lawn mowers do have this, because the operator does not constantly adjust the throttle as they are chipping wood, or c
