摘要： An internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via a mixture passage. An accumulation valve is arranged in the mixture passage and opened during the compression stroke. The mixture passage is connected to the combustion chamber at an opening formed on the peripheral inner wall of the cylinder head. The opening of the mixture passage is covered by the rear face of the raised portion formed on the top face to the piston when the piston reaches the top dead center.

摘要： An internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The accumulation chamber is filled with catalyzer pellets for reforming the combustible mixture accumulated in the accumulation chamber. The accumulation valve is opened during the compression stroke. In the first half of the compression stroke, a jet of the reformed combustible mixture is spouted into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber where the combustible mixture accumulates under high pressure, and the mixture is then spouted into the combustion chamber at the next cycle, from the accumulation chamber.

摘要： An internal combustion engine is provided with an auxiliary piston reciprocating within an auxiliary chamber for generating turbulence in a gas mixture contained within a main combustion chamber. Forward motion of the auxiliary piston causes the injection of a gas into the main combustion chamber through a communicating passageway when the main piston approaches top dead center of the compression stroke.

摘要： An internal combustion engine comprises a cylinder block and a cylinder head. A combustion chamber is formed in the cylinder block and the cylinder head. An accumulation chamber is formed within the cylinder head and communicated with the combustion chamber via an operating valve. The accumulation chamber is disposed adjacent to an exhaust port of the engine and is heat exchangeable with the exhaust port. The operating valve is opened approximately at the time the compression stroke is commenced and is closed approximately at the time the compression stroke is completed. A cap is disposed at the entrance of the accumulation chamber and has a plurality of jets formed thereon. The compressed combustible gas mixture is accumulated within the accumulation chamber, heated by the heat transmitted from the exhaust port and spouted out into the combustion chamber, so that approximately uniform turbulences are generated in the combustion chamber and the flame speed is increased.

摘要： Disclosed is an internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The opening operation of the accumulation valve is controlled so that the accumulation valve remains opened during the compression stroke. Fuel is fed into the accumulation chamber to form therein a rich mixture. In the first half of the compression stroke, a jet of the rich mixture is spouted out into the combustion chamber from the accumulation chamber to stratify the inside of the combustion chamber so that the rich mixture is collected around the spark plug. In the latter half of the compression stroke, a lean mixture in the combustion chamber flows into the accumulation chamber to accumulate the mixture under high pressure, which is spouted out into the combustion chamber at the next cycle, in the accumulation chamber.

摘要： An internal combustion engine with an exhaust gas accumulation chamber, a valve for controlling the flow of the exhaust gas into and from the exhaust gas accumulation chamber and a communicating passage for communicating the cylinder bore of the combustion chamber with the exhaust gas accumulation chamber, along which cylinder bore the piston is reciprocated. The valve is open from a first time in the compression stroke to a second time in the succeeding expansion stroke. Due to the combined operation of the valve and the movement of the piston, the exhaust gas is accumulated within the accumulation chamber only near the end of the expansion stroke and is spouted from the accumulation chamber only in the beginning of the compression stroke. The communicating passage is so arranged that the exhaust gas spouted from the accumulation chamber into the combustion chamber generates a swirl motion in the combustible gas mixture.
