摘要： A lubricating system for a two-stroke engine is provided in which oil is more reliably pumped into the two-stroke engine. The oil travels through passages that are integrally cast into the cylinder and/or crankcase. The oil may be injected directly into the crankcase chamber or intake passage. The oil pump may be a rotary pump mounted on the crankcase concentric to the crankshaft. It is also possible to not use an oil pump, and have the oil drawn into the engine by vacuum created in the crankcase.

摘要： An engine (10) has a block with a crankcase chamber (22) and two cylinders (24, 26) extending radially from the chamber (22). A piston (56, 60) reciprocates in each cylinder (24, 26). The crankcase chamber (22) accommodates a crankshaft (64) which causes the pistons (56, 60) to move in diametrically opposite directions. At any time, both pistons (56, 60) are moving either towards top dead center or towards bottom dead center. An injector (88) is arranged to admit a fuel mixture into the crankcase chamber (22) through an inlet opening (90) whenever the two pistons (56, 60) move towards top dead center. Two transfer tubes (98, 100) extend from an outlet opening (94) in the block to the combustion chambers of the respective cylinders (24, 26). The volume of fuel mixture drawn through the inlet opening (90) when the pistons (56, 60) move towards top dead center equals the sum of the displacements of the pistons (56, 60). The greater part of this volume is forced into a combustion chamber during an intake stroke with an accompanying precompression.

摘要： The effectiveness is prolonged for catalytic oxidizers to reduce emissions of both HC and CO from two-stroke gasoline engines. A compound of a platinum group metal is added to the cylinder of the engine to make it available as an active oxidation catalyst by combustion of the fuel. Preferably, the platinum group metal compound is added with the lubricating oil, but can be added to the fuel or through a separate injection.

There is provided within an engine housing (28) an oil reservoir (126) and a valve chamber (156) which independently communicate with a crank chamber (124). A strategically placed divider (116) and passageway, located within the engine housing (28), appropriately direct lubricant within the engine housing (28) so that the internal cavity of the engine is lubricated during use in various operating attitudes, and so that the fluid flows to and is held in the proper chambers of the engine housing during storage. There is also provided a breather arrangement for an internal combustion engine (20) which includes a cam shaft (98) having a hollow passageway in communication with the crank chamber (124) and the air intake system of the engine. There is also provided an engine housing which can be utilized for engines having different horse power ratings. There is also provided a crankshaft bearing assembly (68, 70) which prevents damage to the bearing upon insertion of the crankshaft (80) into the crank chamber (124).
