Question: What is the principle of diesel engine?

Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously.

What is the main difference between diesel engine and petrol engine?

The primary difference (as most of you already know), is that petrol engines use spark plugs to ignite the air-fuel mixture, while diesel engines rely on heavily compressed air without any spark plugs.

Is a diesel engine better than petrol?

Diesels are more fuel efficient than petrol engines and emit less CO2, which makes them better for the environment. Diesels produce considerably more torque (pulling power) than their petrol counterparts, which makes them good engines for towing or carrying heavy loads – ie: seven occupants – on a regular basis.

What if petrol is used in diesel engine?

Putting petrol in a diesel car can cause serious damage to the fuel injection system and engine. … When petrol is added to diesel it reduces its lubrication properties, which can damage the fuel pump through metal-to-metal contact and create metal particles causing significant damage to the rest of the fuel system.

Which is not functions of fuel injection system?
