摘要： The invention relates to an internal combustion engine with direct injection and supercharging in which 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 of a TCV installed in the suction port which is a divided spray and air flow generation mechanism and by the valve timing control of the suction and exhaust valve, etc.

摘要： The present invention relates to an engine supercharging system and is intended to sufficiently fulfill the supercharging function at the time of either of low speed running of the engine and high speed running and realizing output improvement or fuel expense reduction. The present invention has the engine (101) having the jet mechanism for directly jetting fuel into the cylinder (101a), the first turbo supercharger (104) for supercharging the engine (101) at the time of low speed rotation, the second turbo supercharger (105) for supercharging at the time of high speed rotation, the first and second exhaust control valves (106 and 107) for selecting exhaust paths relating to the first and second turbo superchargers (104 and 105) and controlling the exhaust gas flow rate.
