What will happen if diesel filled in petrol engine?

Putting diesel in a petrol engine is a very bad idea, and will likely cause significant damage. Here's why:

Diesel vs. Petrol (Gasoline):

* Fuel Ignition: Diesel engines use compression ignition. The fuel ignites due to the high heat generated by compressing air in the cylinder. Petrol engines use spark ignition, where a spark plug ignites the fuel.

* Fuel Properties: Diesel fuel is thicker and less volatile than petrol. It also has a higher flash point (temperature at which it ignites).

* Fuel System: Petrol and diesel engines have different fuel delivery systems, pumps, injectors, and combustion chambers.

What happens when you put diesel in a petrol engine:

1. Poor Combustion: The diesel fuel will not ignite properly in the petrol engine's combustion chamber due to the spark ignition system.

2. Engine Stalling: The engine will likely run poorly, sputter, and eventually stall.

3. Fuel System Damage: The diesel fuel can clog the fuel injectors, fuel lines, and other parts of the fuel system designed for petrol.

4. Engine Damage: The thick diesel fuel can cause damage to the pistons, cylinder walls, and other engine components.

5. Oil Contamination: Diesel can contaminate the engine oil, reducing its effectiveness and potentially damaging the engine bearings.

What to do if you accidentally put diesel in a petrol engine:

1. Stop the Engine Immediately: Do not attempt to start the engine again.

2. Contact a Mechanic: A professional mechanic will need to drain the fuel tank, flush the fuel system, and inspect for any damage.

3. Don't try to "fix" it yourself: Trying to resolve the issue yourself could worsen the damage.

It's important to remember:

* Prevention is key: Always double-check the fuel type before filling your car.

* Use the correct fuel: Filling your car with the wrong fuel can be costly and damaging.

In short, putting diesel in a petrol engine is a mistake that can lead to serious engine damage and costly repairs. Seek professional help immediately if you accidentally do this.
