Ok so a nitro engine works in much the same way as a 2 stroke engine and runs on nitro-methanol.
Nitro methanol is normally made up of 25%nitro 9-15% oil and the rest methanol.
Nitro engine do not use a spark to ignite the fuel instead they use a glow plug which is much like a heater plug in any diesel engine. The fuel is compressed against the hot plug and the explosion happens. Now when the engine is running the heat from the explosions keeps the glow plug hot enough to ignite the next lot of compressed fuel. Before the engine will start the glow plug needs to be hot and with no on-board power source we use a glow clip to power in then remove it once the engine is running
as simple as i can put it really
