  • Patent number: 9670881
    Abstract: A supercharger-equipped internal combustion engine in the present invention includes a turbo-supercharger (20) which includes, at some point in an intake passage (26), a centrifugal compressor (20b) having an impeller section (20b4) for housing a compressor impeller (20b3). In the supercharger-equipped internal combustion engine, EGR gas and blow-by gas are introduced into an intake system in such a way as to flow into the centrifugal compressor (20b) via an EGR gas introduction section (40a) and a blow-by gas introduction section (48a). The supercharger-equipped internal combustion engine further includes a partition wall (52) which guides the EGR gas and the blow-by gas toward the centrifugal compressor (20b) so that the EGR gas and the blow-by gas are not mixed with each other until the EGR gas and the blow-by gas enter into the impeller section (20b4).

  • Patent number: 9541016
    Abstract: Provided are a throttle control device for an internal combustion engine and a throttle control method for an internal combustion engine, which are capable of avoiding occurrence of overshoot of a supercharging pressure at the time of deceleration to improve durability of components in an engine equipped with a supercharger. The engine equipped with the supercharger includes a bypass passage which bypasses a turbine of the supercharger. In the bypass passage, a wastegate valve for adjusting a flow-path area of the bypass passage by a wastegate actuator is provided. An ECU (50) increases the flow-path area of the wastegate valve for deceleration to be started during a high-load operation and closes a throttle valve after confirming that a throttle-valve upstream pressure becomes lower than a predetermined value. As a result, the overshoot of the throttle-valve upstream pressure can be avoided reliably.

  • Patent number: 9482146
    Abstract: A system, apparatus and method for maintaining power in an internal combustion typically turbocharged aircraft engine is disclosed. During descent, air pressure and temperature in the manifold can fall to dangerous levels. This is because engine power is low and likewise turbocharger output is also low. The system and method provide for a bypass of the heat radiator during low power periods, or with low ambient temperature or both. A parameter is measured, often manifold pressure or temperature and the degree of bypass is adjusted commensurately.
