Abstract

PURPOSE:To reduce the amount of unburned HC in the main combustion chamber by providing a spark plug in a sub-chamber and by forming ajet nozzle connecting the main chamber and the sub-chamber in a manner that it is pointed in the circumferential direction of the main chamber so that the jet of flame from the sub-chamber promotes the combustion in the neighborhood of the cylinder wall. CONSTITUTION:To a cylinder head 3 is fitted a sub-chamber 6 in an eccentric position, therein is formed a sub-chamber area 7. A jet nozzle 8 connecting the main chamber 5 and sub-chamber 7 is formed in a manner that it is pointed in the circumferential direction of a cylinder 2 and a spark plug 9 is placed in the sub-chamber. when the spark plug 9 in the sub-chamber 7 is fired approximately at the same time or a little later than the ignition in the main chamber, the air-fuel mixture in the sub-chamber 7 burns to turn into high-temperature and high-pressure gases, which are forced into the main chamber 5 through the jet nozzle 8. Thus the jet stream of gases proceed at a very high speed and collide with the wall of the main chamber 5 to cause violent disturbances to the quenching layer so that it is separated from the wall to get mixed with the high-temperature burned gases. this makes it possible to achieve better combustion of the air-fuel mixture, thus so much reducing the amount of unburned HC.
