What is the purpose of diesel engine?

Answer 1

The purpose of a diesel engine is to convert the chemical energy stored in diesel fuel into mechanical energy for powering vehicles and machinery. Diesel engines are known for their efficiency, durability, and ability to produce high torque at low speeds, making them ideal for heavy-duty applications like trucks, buses, and industrial equipment. They operate using compression ignition, where air is compressed to a high pressure and temperature, igniting the injected fuel. This process results in greater fuel efficiency and lower CO2 emissions compared to gasoline engines.
