The present invention discloses a two-dimensional engine, including a driving device, a two-dimensional gas compressor, a gas outlet pipe, a refueling device, a safety device, an electric ignition device, an axial-flow gas compressor, and a crank connecting rod mechanism, wherein the electric ignition device is arranged on a left side of the gas outlet pipe; the crank connecting rod mechanism is arranged below the gas outlet pipe; the driving device includes a first motor, a first gear, a first dowel bar and a first rack that is arranged on the first dowel bar; the first rack is meshed with the first gear; and the two-dimensional gas compressor includes an upper pressure plate, a first cylindrical plate, a second cylindrical plate, a fixing rod, a first pressure-bearing plate, a second pressure-bearing plate and a shell. The present invention has the beneficial effects of simple structure and relatively high energy utilization rate.

A cylinder head assembly for an internal combustion engine includes a cast cylinder head and a turbocharger housing integrally cast with the cylinder head and having an integrally cast wastegate housing. The turbocharger housing is configured to receive a turbocharger cartridge rotatably supporting a shaft coupled between a compressor wheel and a turbine wheel. The integrally cast wastegate housing defines a wastegate chamber configured to receive a wastegate valve, a flow of exhaust gas from the turbine wheel, and a flow of wastegate exhaust gas.

A product may include a bearing housing in which a shaft may be supported by a bearing so that it may rotate. A compressor wheel may be disposed on the shaft. A compressor cover may be connected with the bearing housing, which may form a compressor body and may define a chamber within which the compressor wheel may rotate. A diffuser may extend radially outward from the chamber and may receive gas from the compressor wheel. An inlet may be provided to the compressor body, which may receive a supply of exhaust gas. An EGR distribution cavity may be defined within the compressor body and may extend around the shaft. An EGR inlet channel may extend into the bearing housing from the inlet to the EGR distribution cavity. An EGR passage may extend from the EGR distribution cavity to the diffuser.

A venting system for a turbocharger may include a bearing housing. The bearing housing may include an inner member. A housing wall may extend from the inner member and may include at least one vent disposed therethrough. A partition may be sealed to the housing wall and the inner member. The partition, the housing wall, and the inner member may collectively form a thermal dam.

A method for controlling a supercharger of a vehicle includes: determining, at a first determination step, whether or not an engine operates in a cylinder deactivation (CDA) mode; calculating, at a second determination step, a difference value between a target boost pressure of a turbocharger and a current boost pressure of intake air boosted by the turbocharger, and determining whether or not the difference value is equal to or greater than a reference difference value; determining, at a third determination step, based on a current operating condition of the engine whether or not the supercharger is allowed to operate; determining, at a fourth determination step, a target rpm of the supercharger, and determining whether or not the target rpm is equal to or greater than a reference rpm; and operating the supercharger at an operating step.
