    Abstract: An internal combustion engine is described comprising a cylinder having an intake port (14), and two manifolds (24, 34) having branches (22, 32) that are configured to supply two gas streams to the intake port (14) of each cylinder. The two streams enter the cylinder separately so as to produce a stratified charge within the engine cylinder. The first manifold (24) supplies a metered quantity of air within which the fuel to be burnt is despersed and the second manifold (34) supplies dilution gases. A flow obstructing throttle (23) is arranged in each branch (22) of the first manifold to reduce the risk of back-filling of the branches (22) of the first manifold (24).

    Abstract: 電気制御装置70は、空気とインジェクタ37から噴射される燃料とを含む混合ガスを燃焼室25に形成し、その混合ガスを圧縮行程にて圧縮することにより自着火させて燃焼させる予混合圧縮自着火運転が可能な内燃機関10に適用される。電気制御装置は、圧縮行程中であって燃料の分解開始時点よりも前の所定の時期において混合ガスの温度の不均一性を増大させるように、空気などの高圧流体を空気噴射弁38から混合気に対して噴射する。これにより、燃料の分解開始峙点における混合ガスの温度の不均一性が、混合ガスを圧縮行程にて圧縮することのみにより生ずる温度の不均一性より大きくなる。その結果、燃焼が緩慢化され、燃焼音が低減する。

    Abstract: The invention relates to a method of adapting the ignition timing in an internal combustion engine to the crankshaft position depending on variations in engine r.p.m., load and overlap between the inlet and exhaust valves. The ratio between combusted and non-combusted gas in the cylinders is computed, and this ratio is utilized, in such a way that the greater the proportion of combusted gas there is, the earlier the ignition will be initiated. The invention also relates to an engine with a control unit (9) and means (11, 13, 14, 15) for computing said ratio, and controlling the ignition timing in the disclosed manner.

    Abstract: The invention relates to an internal combustion engine, especially one with spark ignition and possibly with a catalyst. On the one hand a new design is proposed and on the other this invention can be applied in certain versions to existing spark ignition engines. The main aim is to reduce the emission of pollutants and/or increase the efficiency. This is achieved by the invention by the blowing of gases which may also contain fuel into the combustion chamber. This primarily generates a controllable, efficient turbulence in the combustion chamber (especially during combustion). The mixture is preferably blown in in pulses and its quantity is controllable depending on the working point. Thus especially cold-starting and warming up and the partial load range of the internal combustion engine are to be improved. In addition, it is proposed to produce a stratified charge by the blowing process.
