Mechanism of Diesel Engines Explained
Diesel engines operate fundamentally on the principle of compression ignition. Unlike petrol engines, which rely on spark plugs for ignition, diesel engines compress air to a high degree, resulting in elevated temperatures that ignite the fuel injected into the combustion chamber.
The mechanism can be outlined in the following steps:
- Air Intake: Fresh air is drawn into the cylinder during the intake stroke.
- Compression: The piston compresses the air, increasing both its pressure and temperature.
- Fuel Injection: At the peak of the compression stroke, diesel fuel is injected directly into the combustion chamber.
- Ignition: The heat generated from the compressed air ignites the fuel, producing a powerful explosion.
This process results in more efficient fuel utilization, leading to superior fuel economy. The unique design of diesel engines allows them to generate higher torque and power compared to their petrol counterparts, reinforcing their position in various industrial and automotive applications.
