Abstract
An internal combustion engine equipped with an ignition chamber and with a homogeneous mixture supply of the main combustion space, in which the fuel-air ratio of the combustion is so controlled dependent on the load of the engine at least over a portion of the rotational speed range that starting from the upper limit of a lower load range, in which an approximately constant large fuel-air ratio exists, it is reduced with increasing load.
Claims30
An internal combustion engine which includes a main combustion space means, ignition chamber means terminating in said main combustion space means, and mixture supply means for supplying a fuel-air mixture to the main combustion space means, characterized in that a further mixture supply means is provided for independently supplying a different fuel-air mixture to the ignition chamber means, and in that the fuel-air ratio of the combustion is controlled by control means in dependence on the load of the engine at least over a portion of the rotational speed range in such a manner that the fuel-air ratio is reduced with an increasing load starting from the upper boundary of a lower load range, in which an approximately constant large fuel-air ratio exists.
An internal combustion engine comprising an ignition chamber means terminating in a main combustion space means, means for supplying a fuel-air mixture to said main combustion space means, means for supplying a fuel-air mixture to said ignition chamber means independently of said fuel-air mixture supplying means of said main combustion space means, and control means for controlling the fuel-air ratio of said main combustion space means to supply said main combustion space means with an approximately stoichiometric air-fuel mixture during an idling and lower partial load range, a reduced approximately constant fuel-air mixture lying approximately near an ignitable limit during a load range between the lower partial load range and an upper partial load range, and continuously increasing the fuel proportion in the fuel-air mixture during the upper partial load range until an approximately stoichiometric mixture is obtained in a full load range.
