Question: What is the working 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.

How do petrol and diesel engines work?

In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. In a diesel engine, however, the air is compressed first, and then the fuel is injected. … The diesel engine uses a four-stroke combustion cycle just like a gasoline engine.

Do diesel engines have points?

In a diesel engine air and fuel are not pre-mixed. … At this point fuel is injected into the hot compressed air causing it to ignite instantly. Higher cylinder pressure is generated, creating more torque to power the vehicle.

What is the main difference between petrol engine and diesel 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.

Can petrol engine replace diesel engine?
