ABSTRACT:
A fuel injection apparatus for a multicylinder gasoline engine controls average engine output torque by omitting fuel from a proportion of the cylinder cycles. This system eliminates the need to heavily throttle the air intake, thus easing engine design and allowing the engine to be operated near its throttle point of peak efficiency. The engine has an electrically actuated fuel injector valve for each cylinder; skipping of fuel rations is controlled electronically.
In order to reduce atmospheric pollution, a special cylinder is exempted from inhibition of its fuel rations in order that it may be used to completely reburn the blowby gases from the other cylinders.
During powered operation, blowby gases from all cylinders accumulate in the crankcase. When the engine power is to be shut off, inhibition of fuel rations to the special cylinder is delayed in order to give it time to reburn the accumulated pollutants in the crankcase.
