Abstract

PURPOSE:To increase the combustion efficiency, by independently admitting oxygen gas and nitrogen gas from a gas generator to a charging passage at a position upstream of an intake valve, and independently effecting the strong activity of the oxygen gas, the abnormal combustion prevention by the nitrogen gas and the medium layer of the mixed gas. CONSTITUTION:An oxygen gas inlet pipe 2a, a nitrogen gas inlet pipe 2b and an air inlet pipe 2c are independently connected to an inlet portion of an intake pipe 2 of a Diesel engine 1 in such a manner as to be directed to an intake valve 1a. That is, a supercharged gas from an exhaust turbocharger 4 is partially fed to a gas generator 5, and is separated into oxygen gas and nitrogen gas by the gas generator 5. Then, both the gases are independently supplied through the inlet pipes 2a and 2b toward the intake valve 1a. The remainder of the supercharged gas is directly supplied through the mixed gas inlet pipe 2c toward the intake valve 1a.
