    摘要: The invention concerns an exhaust gas cleaning system for an internal combustion engine with at least one catalytically active component which is configured such that its catalytically active coating comprises at least a first region with high light-off temperature and a high temperature resistance and at least a second region with a low light-off temperature and a reduced temperature resistance (relative to the first region). The exhaust-gas-side surface of the catalytically active coating in the intake region of the catalytically active component has at least a partial diffusion layer, or is at least partially covered by a diffusion layer.

    摘要: In a two cycle internal combustion engine with uni-directional flow scavenging wherein a piston is disposed in a cylinder so as to be movable between top and bottom dead center end positions, the cylinder has fresh air inlet passages which are so arranged that their bottom walls are disposed below the piston top edge when the piston is in its bottom dead center position so that part of the piston top land is directly exposed to the fresh air flow through the air inlet passages and oil discharge bores extend from the air inlet passages and are in communication with the oil circulating system for the removal of oil wiped off the cylinder wall and collected in the inlet passages.
