Publication number: 20170350308Abstract: Systems are provided for cooling combustion chamber gasses and increasing an amount of air entrained in an injected fuel spray. In one example, a cooling passage may be included in an internal combustion engine, the cooling passage positioned exterior to a cylinder bore of the engine and coupled to the cylinder bore at a first opening and a second opening. The cooling passage may receive gasses from the cylinder bore via the first opening, and may cool the gasses as they travel through the cooling passage before returning the gasses to the cylinder bore via the second opening.Type: ApplicationFiled: June 1, 2016Publication date: December 7, 2017Inventors: Christopher Polonowski, Eric Matthew Kurtz, Daniel William Kantrow, Jianwen James Yi

Publication number: 20170350315Abstract: A supercharging system includes a supercharger including a motor generator, and an intake-side variable cam phase mechanism variably setting a valve-closing timing (IVC angle) of an intake valve. If an operation state of the engine is within a regenerative operation region, a turbine rotation speed controller controls a turbine rotation speed to a target turbine rotation speed set to optimize turbine efficiency by controlling an opening degree of a wastegate valve toward a closing side and by adjusting an amount of power generated by the motor generator. If the operation state is within the regenerative operation region and within a supercharging operation region, a torque controller controls a generated torque to a requested torque by performing cooperative control of an opening degree of an intake bypass valve, the IVC angle and an opening degree of an intake throttle valve.Type: ApplicationFiled: June 7, 2017Publication date: December 7, 2017Applicant: Honda Motor Co.,Ltd.Inventor: Junichi KAMIO
