Abstract: A rotary internal combustion engine with a housing having a fluid passage defined therethrough opening into a portion of its inner surface engaging each peripheral or apex seal of the rotor. An injector has an inlet for fluid communication with a pressurized lubricant source and a selectively openable and closable outlet in fluid communication with the fluid passage for delivering the pressurized lubricant to each seal through the fluid passage. A housing for a Wankel engine and a method of lubricating peripheral seals of a rotor in an internal combustion engine are also discussed.

Abstract: Intake and exhaust cam shafts are disposed a cylinder head in a vertical direction. The cylinder head comprises a first through hole and a second through hole. The first through hole penetrates an upper surface deck from a deck surface towards a lower surface of the cylinder head. The deck surface is a surface constituting an upper surface deck of the cylinder head. The second through hole opens to a side surface of the cylinder head in which cam pulleys of intake and exhaust cam shafts are provided. The second through hole penetrates the upper surface deck along an axial direction of the intake and exhaust cam shafts. The second through hole is positioned vertically below an opening in the deck surface of the first through hole.

Abstract: Disclosed is lubrication for a slow-running two-stroke engine, especially marine diesel engines. The lubrication uses Swirl Injection Principle by locating the lubricant injectors closer to the TDC than ⅕ of the full stroke of the piston, which is closer than in typical marine diesel engines. This can be achieved by reconstructing cylinder liners or by adding new mounting holes to the cylinder. In case that such reconstruction is not possible, an improvement of SIP principles can also be achieved by directing the spray towards the TDC or to a location on the cylinder liner closer to the TDC as compared to the location of the SIP valves, for example under an angle of more than 30 degrees or even more than 60 degrees when measured from a plane normal to the cylinder axis.

Abstract: This oil return structure is provided with a flow passage body configured to return oil into an engine body which communicates with an oil storage section of the engine, the oil having been separated from a blow-by gas by an oil separation means. The upstream end of the flow passage body is connected to the oil separation means, at least a portion of the downstream side of the flow passage body protrudes into the engine body from the inner wall thereof, and an oil discharge opening at tire downstream end of the flow passage body is disposed at a position not immersed in oil within the oil storage section.

Abstract: A crankcase includes: a main body portion aligned with a drive motor in a direction perpendicular to a motor drive shaft; and an extended portion continuous with the main body portion and located lateral to a motor housing, the extended portion receiving insertion of one end of the motor drive shaft. A power transmission mechanism that transmits power from the motor drive shaft to an input shaft is located partly in a first region defined by the main body portion and partly in a second region defined by the extended portion and communicating with the first region.
