It was established to the system, which adapted combustion system not following spark ignition system without any ignition apparatus. It was heated and controlled inlet-air into conventional single cylinder engin. Adapting the method of increasing inlet-air heating temperature made possible enhanced the compression ignition cbaIacteristics of gasoline fuel injected to intake-port. It was established the compression ignition gasolin engin. So, the system was investigated the emission characteristics of compression ignition gasolin engine. The conclusions of combustion emission chracteristics are as followed.
The gasoline compression ignition system made possible to run lean bum(over air-fuel ratio 30) the engine, and emission of carbon monoxide was emitted little about the changes of air-fuel ratio. Inlet-air heating temperature and the changes of engine speed were hardly got influenced. The emission of hydrocaIbon was increased as much as air-fuel ratio's increased
But the ranges of changes was very narrow. It was emitted little only as much as 2 ppm and 4 ppm within the changes of inlet-air heating temperature and engine speed. The emission of nitrogen oxide was decreased greatly as much as air-fuel ratio was decreased. When air-fuel ratio was over 45, the emission of nitrogen oxide was emitted little in case that the changes of inlet-air heating temperature and engine speed.
The achievements of gasoline compression ignition system could improved that the emission concentrations of carbon monoxide, hydrocarbon and nitrogen oxide were reduced greatly.
