Abstract
PURPOSE: To control knocking and to improve the fuel cost at the time of high-load operation by providing a squish area in a combustion chamber and by extending the lower deck of a cooling-water jacket out to a position inside a cylinder bore.
CONSTITUTION: A suction valve 7, an exhaust valve 7 and two ignition plugs 9 are arranged in positions located nearly in point symmetry to the center of the cylinder bore 3. Squish surfaces 11 and 12 are formed of a cylinder head 4 and the head part of a piston 5, while the lower deck 15 of the cooling-water jacket 14 is extended out to the position inside the cylinder bore 3. Since the squish flow of unburnt mixture gas produced at the time of completion of a compression stroke of the engine can be controlled to be at low temperature by this cpnstitution, knocking can be controlled.
