摘要： Controlled amounts of relatively rich mixture and relatively lean mixture are supplied separately to a combustion chamber of an internal combustion engine. The position of the intake valves, exhaust valve and spark plug are such that the rich mixture tends to remain near the spark plug during the compression stroke of the engine and does not disperse throughout the lean mixture. At the time of ignition enriched mixture near the spark plug ignites readily and the flame propagates into and through the lean mixture which fills the remainder of the combustion chamber. Several constructions are disclosed to achieve the desired mixture ratios for various operating conditions of the engine.

摘要： The auxiliary combustion chamber of a four-cycle stratified-charge piston engine is divided into a primary cavity and a secondary cavity. The primary cavity receives a relatively rich mixture which passes into the secondary cavity, and the main combustion chamber receives a relatively lean mixture. The primary cavity is in communication with a spark plug. A long torch passage connects the primary cavity with the central portion of the main combustion chamber, and one or more short torch passages connect the secondary cavity with a peripheral portion of the main combustion chamber. The purpose is to reduce emission of NO.sub.x without adversely affecting emissions of CO and HC, and to improve fuel economy.

摘要： An internal combustion piston engine has a main combustion chamber and an auxiliary combustion chamber connected by a torch passage, which is tapered end to end, the large end communicating with the main combustion chamber. Lean mixture is supplied to the main combustion chamber and rich mixture is supplied to the auxiliary combustion chamber. A spark plug ignites the mixture in the auxiliary combustion chamber, causing a torch flame to be projected through the tapered torch passage into the main combustion chamber near its center. A suction conduit, smaller in diameter and total area than any portion of the tapered torch passage, extends from a peripheral portion of the main chamber and intersects the tapered torch passage between its ends. Movement of the burning gases through the torch passage aspirates a flow of mixture from the main combustion chamber through the suction conduit into the torch passage.

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： An internal combustion piston engine has a main combustion chamber and an auxiliary combustion chamber connected by a torch passage. On the suction stroke of the piston lean mixture is drawn into the main combustion chamber and rich mixture is drawn into the auxiliary combustion chamber. A spark plug ignites the mixture in the auxiliary combustion chamber at the end of the compression stroke, causing a torch flame to be projected through the torch passage into the main combustion chamber near its center. A suction conduit, smaller in diameter and total area than the torch passage, extends from a peripheral portion of the main chamber and intersects the torch passage between its ends. Movement of the burning gases through the torch passage aspirates a flow of mixture from the main combustion chamber through the suction conduit into the torch passage.

摘要： An outboard motor includes an engine. A cowling body defines an internal cavity in which the engine is enclosed. A partition member divides the internal cavity into a first cavity and a second cavity. The first cavity communicates with outside through a first opening for introducing ambient air into the first cavity. The second cavity encloses the engine therein. The partition member has a second opening through which the air in the first cavity moves to the second cavity. The cowling body and the partition member are made of a nonferrous metal. The partition member is adhered to the cowling body.
