Abstract
An injection installation for internal combustion engines, especially for mixture-compressing internal combustion engines operating with charge stratification, which essentially consists of an injection pump and of injection valves coordinated to the cylinders of the internal combustion engine; a metering mechanism is thereby arranged in each injection valve which with a feed of the injection pump supplies a metered quantity of fuel to the nozzle discharge of the injection valve while the injection pump is so constructed that it always supplies a multiple of the metered quantity of fuel independently of load and rotational speed of the internal combustion engine whereby the excess quantity of fuel flows back into the fuel tank by way of a return line connected to the injection valve.
Claims21
An injection installation for internal combustion engines, comprising injection pump means and injection valve means coordinated to the cylinders of the internal combustion engine, characterized in that a metering means is arranged in each injection valve means which is operable with a feed of the injection pump means, to feed a metered quantity of fuel to the nozzle discharge of the injection valve means, the injection pump means being so constructed that it always feeds a multiple of the metered quantity of fuel independently of load and rotational speed of the internal combustion engine, the excess quantity of fuel, thus fed from the injection pump means, being discharged back to a fuel tank adapted to be connected to the injection valve means by way of a return line.
