Internal combustion engine

摘要

An internal combustion engine operating with applied ignition and with minimum-quantity-injection into an ignition chamber terminating in a main combustion space which is variable in volume, and in which the main combustion space is additionally supplied with fuel; the minimum-quantity injection nozzle coordinated to the ignition chamber is thereby connected in a fuel circulatory system into which is fed a substantially constant fuel quantity exceeding the injection quantity for the minimum-quantity injection nozzle; a throttle cross section is provided in the return of the fuel circulation downstream of the minimum-quantity injection nozzle while the supply of the fuel to the main combustion space takes place by way of a suction-pipe injection system, whereby the suction-pipe injection quantity is branched off from the return of the fuel circulation and is controlled as a function of load by the adjustment of the throttle cross section in dependence on the load.
