Sorry but this has way too many unknowns to answer properly. (Engine size, engine temperature, idle or throttled, air conditioning, charged battery, headlights) A few minor trends though can be specified. While an engine is cold, more fuel will be consumed to bring the engine up to temperature. Most modern automobile engines have been designed so lean that when added mechanical loads are engaged like air conditioning, and battery charging; more fuel is consumed to compensate. Older, typically carbuerated engines were set to consume enough fuel at idle to not stall the engine with all mechanical loads engaged.

Why petrol csnnot be used in diese engine?

The diesel engine is designed to use diesel, which reaches combustion at high (relatively to petrol) pressure and temperature. If petrol is injected into a diesel engine, then combustion will take place in a, very different than it was designed, way, which will eventually destroy the engine. But there are engines that have been designed to burn diesel or petrol. They call them bifuel engines. Old farmer tractors used to have this kind of engines.


Why is diesel is not used in petrol engines?

Because diesel is ignited of heat and high high compresion not a spark on lower compresion petrol engine. If you use diesel in a petrol you will end up with your engine knocking and pre-detonation followed by your engine blowing up pretty bad.


Why in petrol engine spark plug is used but not in diesel engine?

Diesel engines run much higher compression than petrol engines. The higher compression makes the air in the cylinder so hot that the fuel self ignites. A petrol engine doesn't get warm enough for self ignition, so you have to add a spark from the spark plug to ignite the fuel.


What phenomenon occurs if petrol is used in diesel engine?

What do you mean phenonmenon? Nothing of a phenomenon occurs. Your engine will simply fail and you will need to get the whole tank cleaned out and system it will cost a fortune. This is why people put diesel stickers on the inside of their petrol cap to remind them. And prob saving them money in the long run!


Why petrol engines are faster than diesel engines?

Petrol engines are widely considered to be the most efficient of engines, because they are more refined than diesel. Since diesel is not completely refined, it cannot completely combust and so does not (in theory) produce as much energy per litre of fuel as a petrol engine. However, some diesel engines can be made to be much more efficient than petrol engines because they have a different type of fuel, and burn it in a different way.

How does a car engine convert petrol to power?

The petrol is burned in the engine where part of the energy released (roughly one-fourth) is used in moving the car, while the rest is lost as heat and sound energy.


Which property of a liquid is used when petrol is pumped in the tank to the engine of a car?

Ah, what a lovely question! When petrol is pumped from the tank to the engine of a car, we are relying on the property of liquids called "flowability." This allows the petrol to move smoothly through the fuel system and reach the engine where it can be used to power the vehicle on its journey. Just like how paint flows on our canvas, petrol flows through the car's system to keep us moving forward on our own unique path.
