The correct answer is dependent on the model engine.

But in general the spark starts several degrees before the piston arrives at Top Dead Centre.

In a diesel engine the air fuel mixture is ignited by?

It is ignited by compression. The air fuel mixture is compressed by the piston going up. Some diesels have glow plugs too that heat up the air fuel mixture so it is more easily ignited.


How is the engine ignited?

A petrol engine is ignited by a spark plug, and a diesel engine is ignited by the heat produced from the air/ fuel mixture being compressed in the cylinder


In a diesel engine the airfuel mixture is ignited by?

it is ignited due to the high temperature caused by the pressure inside cylinder, when it is compressed.


What is internal-combustion engine?

An internal combustion engine is one where a gas/air mixture is ignited and burned in a closed cylinder, and forces a piston to move. In other words, all piston engines in cars, trucks, bikes aircraft.


In what type of engine is the air and fuel mixture ignited by the heat created during the compression stage?

The air and fuel mixture is ignited by the heat created during the compression stage in a compression ignition engine, also known as a diesel engine.


If you have a container with hydrogen gas and oxygen gas what do you have?

You have a mixture that can be easily ignited to form water vapor.


How does a jet engine work in a fighter aircraft?

The air passes through the air intake in the front area of the aircraft and then mixes with the fuel which is ignited and then sent out the back causing its thrust. A slightly more complicated answer follows the standard operation of Suck, Squeze, Bang, Blow. Air is actually SUCKed into the intake by a rotary air compresser at the heart of the engine. The compressor vanes SQUEEZE the air to high pressures where it is then mixed with fuel. The mixture is then ignited (BANG) where it is BLOWn out of the back of the engine creating thrust.


What is a chemical reaction that occurs when a mixture of gasoline and air is ignited by a spark called?

This reaction is called combustion.


What liquid and gas can create a mixture?

Fuel and air can create a mixture in an internal combustion engine, where the fuel (liquid) is mixed with air (gas) before being ignited to power the engine.


How does a nitro engine work?

The operation of a nitro engine is similar to a normal gas/diesel engine, where a fuel mixture is ignited, and the energy drives cylinders back and forth in a cycle, all the while keeping an element hot so that the fuel stays ignited. The only difference is that a nitro mixture is more complicated, so a hole has to be bored into the engine so the mixture can keep flowing in a certain way.

What does the intake valve do?

Intake valve allows the atomized fuel mixture to enter the combustion chamber to be ignited by spark plug creating detonation
