1. What ignition engine
common spark ignition engine ignition and compression-ignition two kinds.
A spark ignition
spark ignition, the full name “spark-ignition”, “spark ignition,” it is a way of forced ignition. An arc between two electrodes of the spark plug discharge principle, igniting the combustible gas mixture ignition and combustion rapidly. When near the end of the compression stroke, the combustible gas mixture consisting of fuel and air is compressed within the cylinder of the piston to a certain pressure and temperature, high voltage immediately 1C? 15kV flow into the ignition plug mounted on the cylinder head, the cylinder spark in the ignition and combustion of combustible gas mixture.
a compression-ignition
is a compression ignition diesel engine ignition. Diesel engines as diesel fuel compared to gasoline, diesel fuel self-ignition temperature is low (about 220 deg.] C), and is not readily evaporate large viscosity. Does not have a spark plug and the diesel engine, the compression ratio should be greater than gasoline engines, diesel engines rely on the compression stroke and therefore the mixed gas is compressed to ignition, it automatically fire, so that this ignition is compression-ignition.
