Title:
FUEL SUPPLY OF SUPERCHARGED ENGINE
Document Type and Number:
Japanese Patent JP3044077
Kind Code:
B2
Abstract:
PURPOSE: To improve the extent of engine power so effectively by setting the injection timing of fuel in a proper manner, and preventing any blow-by from occurring as improving the carburetion and atomization of fuel spray.
CONSTITUTION: It is provided with a supercharger 10, installing a fuel injection valve 12 spraying and supplying fuel to an intake port 8 at each cylinder 2. Fuel is sprayed and supplied from each fuel injection valve 12 after synchronizing with the inlet-exhaust timing of each corresponding cylinder 2. In this constitution, there are provided a judging means, which detects load of an engine 1, and on the basis of this detection, judges whether it is in an engine supercharging driving range or not, and a control means which controls each fuel injection valve 12 so as to spray the fuel during a valve overlap period when an intake valve 9 and an exhaust valve 16 both are opened at the time of the supercharging driving range, and also controls the valve 12 so as to make the injection start timing advance earlier than the injection start timing at the supercharging driving range at the time of a nonsupercharging driving range, respectively.
