摘要
A fuel system for a mixture-compressing, spark-ignited four cycle internal combustion engine with charge stratification of the type wherein a major portion of the charge is introduced into a main combustion chamber as a lean fuel-air mixture by a main mixture forming system such as a carburetor and wherein the remainder of the charge is introduced into an auxiliary combustion chamber joined to the main combustion chamber via a firing channel by an auxiliary combustion chamber injection pump and injection nozzle is improved by the provision of only a single fuel feed pump which is connected to the fuel tank and supplies fuel from the tank directly to the injection pump at a first pressure and supplies fuel to the main mixture forming system via a pressure reducing valve at a second pressure that is lower than the first pressure. According to a preferred embodiment, the single fuel feed pump supplies fuel to the injection pump at a pressure of 1 bar and the pressure-reducing valve is a pilot valve that reduces the pressure of fuel supplied to it to 0.2 bar.
