Abstract

PROBLEM TO BE SOLVED: To solve problems of the mechanism of a conventional diesel engine having a limit to an air intake quantity, which results in leaving a large quantity of noxious substances due to incomplete combustion in exhaust gas after explosive burning and also causes air pollution. SOLUTION: An air injection nozzle is installed in a cylinder head of the engine besides a conventional fuel injection nozzle for supplementing the air shortage, which is a cause of the incomplete combustion in the explosive burning. Right after the explosion of the engine, the compressed air is directly injected to a main combustion chamber so as to supplement the air shortage in burning.
