Are Gasoline Cars or Diesel Cars More Fuel-Efficient?
1 Answers
Diesel cars are more fuel-efficient than gasoline cars. Here are some introductions about diesel cars and gasoline cars: 1. Reasons for fuel efficiency: Diesel cars are more fuel-efficient than gasoline cars, which is determined by the technical characteristics of the engine. Because the compression-ignition diesel engine has a higher energy conversion ratio than the spark-ignition gasoline engine, the energy consumption is 45%-60% of that of the gasoline engine. 2. Power: The low-speed torque of diesel engines is greater than that of gasoline cars. With the same displacement, when starting and climbing hills, you will feel that the diesel car has stronger power. Compared with gasoline, diesel is less volatile, has greater power, and a higher ignition point. Small diesel engines are one-third more fuel-efficient than gasoline engines. The compression-ignition diesel engine has a higher energy conversion ratio than the spark-ignition gasoline engine, and the energy consumption is 45%-60% of that of the gasoline engine.
