A rotational combustion engine that generates force from the reciprocal motion and centripetal motion of one or more pistons that is then converted into rotational motion of a first cam and second cam wherein the cams are separated by a 2-3 degree horizontal offset and an angle of 60 degrees as well as camshaft assembly and driving shaft to provide power to an entity such as an automobile.

An engine assembly including an internal combustion engine configured to be received in an engine compartment and a heat exchanger having a first conduit fluidly connected to a fluid circuitry of the engine and a second conduit fluidly connecting an interior of the engine compartment to its environment. The first conduit is in heat exchange relationship with the second conduit. The assembly further includes a forced air system operable in use to provide an air flow from the environment to the outlet via the second conduit of the heat exchanger and the engine compartment. The assembly further includes a selector valve configurable to selectively fluidly connect an air intake of the internal combustion engine with the interior of the engine compartment in a first valve position and with the environment in a second valve position. A method for supplying air to an internal combustion engine is also discussed.

A rotary internal combustion engine includes a housing, a front cover, a rear cover, and a rotor. The rotor contains 2 or more pair of radially arranged, synchronously geared, crank shafts. The main journal of every other crankshaft has a timing gear at one end and a drive gear at the other. The timing gears mesh with a stationary sun gear fixed to the front cover. The rotor contains radial cylinder bores, each with a piston and connecting rod operably connected to each crankshaft. An output shaft with a sun gear pierces the center of the rotor and meshes with the drive gears. The rotor revolves around the output shaft within the housing which contains ports for intake, fuel delivery, spark, and exhaust. The crankshafts rotate at twice the rate of the rotor, thus producing four piston strokes per revolution of the rotor.

To control the degradation of the emission performance when starting an engine on a vehicle equipped with an engine for driving a generator, the vehicle comprises a generator, an engine, and a catalyst device, a control unit (PCU) that is configured to execute a power generating operation mode after executing an initial mode to activate the catalyst device by operating an electric heater (EHC) when the generator starts power generation by starting the engine, a connecting passage (EGR passage) that connects mutually an intake passage and an exhaust passage, and an adjusting valve (a throttle valve, an exhaust shutter valve, and an EGR valve) for adjusting a flow rate of the gas in the connecting passage. The control unit performs motoring of the engine in the reverse rotation direction by the generator in the initial mode.
