Patent number: 10180103Abstract: Disclosed herein is a technique for providing an engine supercharger allowing an exhaust gas to efficiently act on a turbine in a wide operating range. A turbine for use in a supercharger includes a turbine housing, a turbine scroll formed inside the housing continuously with a turbine lead-in route, and a turbine wheel to turn on an axis of rotation close to a tongue portion. The turbine lead-in route is partitioned by a partition wall into first and second lead-in routes. Exhaust variable valves are provided upstream of the second lead-in route in order to change the flow rate of the exhaust gas to be introduced. When viewed in the direction in which the axis of rotation extends, a downstream end of the partition is aligned with the axis of rotation and the tongue portion.Type: GrantFiled: February 2, 2017Date of Patent: January 15, 2019Assignee: MAZDA MOTOR CORPORATIONInventors: Yoshiyuki Uehane, Junji Umemura, Hideya Horii, Tomoaki Fujiyama

Patent number: 8033272Abstract: There is provided a method of controlling an engine system having an internal combustion engine, a supercharger arranged in an intake air passage of said internal combustion engine and a motor capable of driving the supercharger. The method comprises, driving the motor to operate the supercharger to boost airflow inducted into the internal combustion engine when the internal combustion engine is in operation. The method further comprises driving the motor to determine a state of the supercharger when the internal combustion engine is stopped and indicating the determined state of the supercharger. According to the method, by driving the motor of the supercharger to detect a state of the supercharger when the internal combustion engine is stopped, the state of the supercharger can be more accurately detected because the condition is most stable.Type: GrantFiled: August 9, 2007Date of Patent: October 11, 2011Assignee: Mazda Motor CorporationInventors: Kenichi Morizane, Hideya Horii

Publication number: 20100250103Abstract: An exemplary method of controlling an internal combustion engine system is described herein. The internal combustion engine system includes an internal combustion engine, a valve driving mechanism which reciprocally drives an intake valve and an exhaust valve for a combustion chamber of the internal combustion engine, a turbocharger including a turbine and a compressor, and a first EGR passage which communicates an exhaust passage downstream of the emission control device and an intake passage upstream of the compressor. The exemplary method includes shutting off supplying fuel to the combustion chamber under a predetermined condition, and decreasing a lift of the intake or exhaust valve for the combustion chamber during the shutting off supplying fuel to the combustion chamber compared to in a case of supplying fuel to said combustion chamber.Type: ApplicationFiled: March 25, 2010Publication date: September 30, 2010Applicant: MAZDA MOTOR CORPORATIONInventors: Daisuke Shimo, Motoshi Kataoka, Yoshihisa Nakamoto, Tatsuya Tanaka, Kota Maekawa, Hideya Horii, Takashi Hatano
