摘要： A rotary engine side housing is provided that includes a side plate portion, a side housing body portion, a coolant chamber, and a plurality of posts. The side plate portion has exterior and interior surfaces. The coolant chamber is disposed internally within the side housing body portion. The coolant chamber is defined by a chamber base surface, the peripheral side walls, and the side plate portion interior surface. The chamber base surface and the side plate portion interior surface are spaced apart from one another and the one or more peripheral side walls extend there between. The plurality of posts extend between the chamber base surface and the side plate portion interior surface. The side plate portion, the side body housing portion, and the plurality of posts are integrally formed with one another.

摘要： An internal combustion engine includes a housing defining an internal cavity, an inner body sealingly moving within the internal cavity for defining at least one combustion chamber of variable volume, a pilot subchamber in communication with the at least one working chamber, an ignition element in communication with the pilot subchamber, a main injector communicating with the at least one combustion chamber, and a pilot injector having a tip in communication with the pilot subchamber. The tip of the pilot injector includes at least a first injection hole defining a first spray direction and a second injection hole defining a second spray direction different from the first spray direction. The first spray direction extends toward the communication between the pilot subchamber and the at least one working chamber. A method of performing combustion in an internal combustion engine is also discussed.

摘要： A method of controlling an air intake flow in a rotary engine having primary and secondary inlet ports, including positioning the secondary inlet port rearwardly of the primary inlet port and forwardly of the exhaust port along a direction of a revolution of the rotor, and controlling air intake flows communicating between an air source and the primary and secondary inlet ports. During engine start-up, a primary valve is closed to prevent the intake air flow between the primary inlet port and the air source and a secondary valve is opened to allow the intake air flow between the secondary inlet port and the air source. A rotary engine defining different compression ratios through actuation of a valve is also discussed.

摘要： An engine includes a housing having a single wall, where the wall has a rib and a flange, and the wall provides a primary structure and cooling for the engine. A closeout is attached to an outer surface of the wall, and the closeout and the wall form a cavity. The closeout provides a secondary structure for containing a coolant fluid flow within the cavity. The closeout may be corrugated, and the ribs may be exposed to the cavity.
