Diesel and petrol engines work differently. Diesel engines use compression to ignite the air/fuel mixture, and have a much higher compression ratio than petrol engines, which use spark ignition. The conditions for ignition are not met when petrol is put into a diesel engine, and will stall.

The diesel battery is bigger as it take a lot more to get a diesel engine going. Best bet is to charge the diesel battery using the petrol, connect the 2 and leave the petrol engine running.


Can you make a diesel engine which works on the basic principle of petrol engine or you can say it uses diesel as a fuel but works on the principle of petrol engine?

No, a diesel is a compression firing engine and a petrol is a spark firing engine. Diesel fuel will not burn in a petrol engine with spark plugs.

Why cant petrol be used in diesel engine?

Because one has a petrol engine and the other has a diesel engine. Petrol/gasoline does not ignite the same way as diesel. It also does not have the lubrication qualities that diesel has. Gas in a diesel engine will damage the fuel system if the diesel very quickly.


Can you use diesel engine instead of petrol engine with using injector instead of spark plug?

No!


Is it possible to use diesel in petrol engine?

No. A petrol or gasoline engine will not run on diesel fuel.


Why compression ratio of petrol enine is 8 where as diesel engine is 22?

because a diesel engine ignites its fuel with pressure, and not with a spark like a petrol engine. that is why a petrol engine does not need as high a compression ratio as a diesel engine


What are the five main difference between petrol engine and diesel engine?

Petrol engine is a spark ignition engine Diesel engine is a compression ignition engine Petrol engine uses petrol or CNG as fuel Diesel engine uses diesel as fuel Petrol engines requires continuous supply of electricity for spark plugs Diesel engine running cost is bit cheaper than petrol engine Petrol engine exhaust is not as black as of diesel engine Diesel engines meter the fuel to control engine output Petrol engines throttle the air to control engine output Diesel engines are about 40% themally efficient Petrol engines are about 25% themally efficient


What happens when you put petrol in a Volvo diesel engine?

What happens is you must remove the petrol immediately. Petrol or gasoline will destroy a diesel engine.


What is the major difference between a petrol car and a diesel one?

The primary difference between a petrol car and diesel car is the consumption rate - diesel and petrol are refined from mineral oil using differing methods. The result is diesel engines having a lower fuel consumption rate than their petrol counterparts when installed in a vehicle of similar mass. CO2 emissions are also lower in a diesel engine than they are in a petrol engine.


What happens if you accidentally put in petrol instead of diesel?

If you put petrol in a diesel vehicle do not start the engine. Petrol will do serious damage to a diesel engine. You must drain all the petrol out and flush the fuel lines.


How do you distinguish between a petrol engine and diesel engine when they are not working?

If the engine has spark plug it is said to be petrol engine, and if it has a pump to inject fuel then it is diesel engine.


How do you distinguish between a petrol engine and diesel engine?

The easiest way is to look for spark plugs. No plugs and it is a diesel, plugs and it is a petrol engine.


How can you convert petrol engine in into diesel engine?

You can convert a petrol engine into a diesel engine by changing the fuel injectors. The fuel filters will also need to be changed.


Can a petrol engine use diesel?

NO! It will not run on diesel.


Can you use diesel in petrol engine?

NO! It will not run on diesel.


What is the difference between petrol and diesel cars?

Diesel can give much better fuel economy (miles per gallon or kilometers per liter) than petrol but the downside is that diesel engines cost more to manufacture than petrol engines. So a petrol-engined vehicle usually costs less money to buy than a similar make and model that has a diesel engine. The design of a petrol-burning engine is different from that of a diesel engine: a petrol engine burns petrol (called gasoline in the US) which is ignited by a spark plug. A diesel engine burns diesel fuel which self-ignites when compressed.


What will happen if petrol is used as a fuel in diesel engine?

Petrol or gasoline in a diesel will cause internal engine damage. if petrol is used in diesel engine it may cause explosive sound with burning ....bcz high compression ratio ......


When petrol is mixed with a diesel engine?

When petrol is mixed with diesel engine the engine will not start due to the following reasons;Fuel in diesel must be compressed at 400o and above to approach compression power while petrol start at 150oPetrol have lower density than that used in diesel enginePetrol use spark ignition lather pressure ignitionPetrol have different octane number than that used in diesel enginePetrol fuel cannot produce much power as that produced in diesel engine with real diesel fuel.Will not accomplish diesel engine phases
