ABSTRACT:
An accumulator fuel injection system for automotive vehicles is provided which includes an accumulating chamber storing therein fuel under a given pressure, a plurality of fuel injectors communicating with the accumulating chamber for injecting the fuel stored therein into engine cylinders of an engine, and a pressure regulator for regulating the pressure of fuel flowing through a drain passage from the accumulating chamber to a fuel tank. When a throttle valve is fully closed during a high-load engine operation, the fuel regulator opens the drain passage to decrease the pressure of fuel within the accumulating chamber to a target pressure level speedily. This allows an actual fuel injection pressure to follow a change in the target pressure level quickly according to an engine operating condition when the throttle valve is reopened.
