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.
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.
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
it is ignited due to the high temperature caused by the pressure inside cylinder, when it is compressed.
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.
You have a mixture that can be easily ignited to form water vapor.
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.
This reaction is called combustion.
This reaction is called combustion.
diesel
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.
