Abstract
In the fuel cylinder injection engine with the supercharging machine, the ignitability deteriorates because the density of the fuel at the spray center becomes excessive due to the shrinkage of the fuel spray under the supercharging. As a result, the density of the smoke and the hydrocarbon exhaust rate increase. The mixture of the fuel and the air under the supercharging is promoted by the control by TCV installed in the suction port which is a divided spray and air flow generation mechanism and the valve timing control of the suction and exhaust valve, etc.
