Whether the diesel engine produces higher torque than the gasoline engine or not.

Expert Solution & Answer
Check Mark

Explanation of Solution

Diesel engines are the internal combustion engines in which the fuel is ignited through the high temperature of the air after an adiabatic compression process.

Gasoline engines are the internal combustion engines that use external source to ignite the fuel in the cylinder.

The diesel engines produce higher torque than gasoline engine due to the following reasons:

  1. 1. The compression ratio of the diesel engine is much higher than the gasoline engines. The high compression ratio results in higher peak pressure in the combustion chamber. This high pressure produces higher torque on the crankshaft compared to the gasoline engines.
  2. 2.  The air-fuel mixture in a diesel engine gets ignited automatically when it is compressed to a high value of temperature and pressure. This combustion produces a surge of energy at an instant due to which a high value of torque is produced.
  3. 3. The diameter of the crankshaft in diesel engines are larger compared to gasoline engines. As the diameter is directly proportional to the torque applied hence the torque in diesel engines are also higher.
