Diesel or Gasoline Cars for Plateau Use?

[Tracey]

Diesel cars are recommended for plateau areas. Here are some comparisons between diesel and gasoline vehicles: 1. Fuel Efficiency: Diesel cars are more fuel-efficient than gasoline cars due to their engine technology. The compression-ignition diesel engine has a higher energy conversion ratio than spark-ignition gasoline engines, consuming only 45%-60% of the energy used by gasoline engines. 2. Power Performance: Diesel engines provide greater low-speed torque compared to gasoline engines. With the same displacement, diesel vehicles deliver more powerful acceleration and hill-climbing performance. Diesel fuel is less volatile than gasoline, has higher power output, and a higher ignition point. Small diesel engines are about one-third more fuel-efficient than gasoline engines. The compression-ignition diesel engine achieves higher energy conversion efficiency, consuming only 45%-60% of the energy required by gasoline engines.
