摘要： A combustion chamber system of a kerosine internal combustion engine including a main combustion chamber and an auxiliary combustion chamber both of which are defined in a cylinder head and are spaced from each other by a partition. A plurality of communication holes through which these main and auxiliary combustion chambers communicate with each other are made in the partition. The main combustion chamber has a suction port and an exhaust port opened thereto which are adapted to be opened and closed by a suction valve and an exhaust valve, respectively. The open ends of the communication holes on the side of the main combustion chamber are pointed to the upper surface of a piston located in the vicinity of a top dead center thereof, and a mixture of a theoretical or richer fuel ratio is fed into the main combustion chamber.

摘要： An internal combustion piston engine of the torch ignition type employs an auxiliary combustion chamber connected by a torch passage to a compact main combustion chamber. A spark plug has electrodes located adjacent the upstream end of the torch passage and remote from the intake valve for the auxiliary combustion chamber. At least one suction conduit intersects the torch passage between its ends and extends from a peripheral zone of the main combustion chamber. This zone may comprise a squish zone which increases flow of air-fuel mixture into the torch passage to follow the torch flame into the main combustion chamber. A cavity in the engine head may receive the torch flame from one or more torch passages.

摘要： Exhaust gas from an internal combustion piston engine is recirculated through a rich mixture auxiliary intake passage leading to an auxiliary combustion chamber. A valve controls the relative proportions of exhaust gas and air supplied to the auxiliary intake passage, and the valve is controlled by means responsive to suction pressure downstream from the auxiliary throttle valve, and is also responsive to movement of that throttle valve.

摘要： An internal combustion piston engine employs a stratified charge. Separate carburetor throats are provided for directing rich air-fuel mixture to a prechamber and lean air-fuel mixture to a main combustion chamber. The rich mixture is heated by the engine exhaust gases and then delivered to the prechamber. A spark plug ignites the rich mixture and causes a torch flame to project laterally through a torch slot in the prechamber wall into the main combustion chamber to ignite the lean mixture contained therein. In this way, the amount of unwanted emissions such as carbon monoxide may be reduced in the exhaust gases discharged into the atmosphere.
