<p>The oval combustion chamber cavity (9) in the piston (3) widens out in a tapered manner towards the cylinder head (1) and is surrounded on all sides by a squish region (18, 18a). The sparking plug (20) is offset by a distance (s) from the median line (37) of the combustion chamber (9) and is disposed in the half of the combustion chamber which contains the exhaust port. When the combustion chamber (9) is used for a four-cylinder, in-line internal combustion engine the sparking plugs (20) of the two outer cylinders (27, 29, Fig. 5) are positioned offset to the outside by the distance (s) with respect to the combustion chamber median lines (37) and the sparking plugs (20) of the two inner cylinders (26, 28, Fig. 5) are positioned offset to the inside towards the median plane (25) of the engine, in order to achieve equally long air induction paths for all the cylinders and an optimum combustion process. <IMAGE></p> |
