  • Patent number: 10458324
    Abstract: A rotary piston engine having a rotor with an output shaft and a plurality of longitudinally extending cylinder-forming bores, each having a slidable piston disposed therein. The rotor is contained in a housing that contains an elliptical cam track that interacts with the pistons, upon combustion, to cause rotation of the rotor. An opening in the housing end cap admits air into the cylinders on the rear side of the pistons and a port delivers air driven by the rear side of the pistons to an intake port in the side of the housing where, in response to the angular position of the rotor, the air is admitted to the front side of a piston for compression with injected fuel. The compressed fuel-air mixture is ignited and an exhaust port in the side of the housing opens to discharge the products of combustion.

  • Patent number: 10443484
    Abstract: In an intake air cooling device, a heat-exchanging core portion in an intercooler has an intake-air downstream-side core portion and an intake-air upstream-side core portion located upstream of the intake-air downstream-side core portion in a flow of intake air. The intake-air downstream-side core portion is located upstream of the intake-air upstream-side core portion in a flow of a cooling fluid. The intercooler has a U-turn portion at which a flow direction of the cooling fluid turns around between the intake-air downstream-side core portion and the intake-air upstream-side core portion. A flow rate control device intermittently supplies the intercooler with a predetermined volume of the cooling fluid at a time. The predetermined volume is a value determined on basis of a volumetric capacity of a cooling fluid channel in the intake-air downstream-side core portion.
