Publication number: 20210324814Abstract: A control device and a diagnostic method according to the present invention is applicable to an internal combustion engine provided with a first fuel injection valve and a second fuel injection valve for a cylinder. When there is an abnormality that makes an air-fuel ratio of the internal combustion engine richer than a specified value, it is determined whether the first fuel injection valve or the second fuel injection valve has the abnormality, based on change of the air-fuel ratio occurring as a result of first injection control for performing fuel injection while changing a distribution ratio of a fuel injection amount distributed to the first fuel injection valve to a fuel injection amount distributed to the second fuel injection valve, and a value of the air-fuel ratio obtained as a result of second injection control for performing fuel injection while maintaining the distribution ratio at a predetermined ratio.Type: ApplicationFiled: March 12, 2019Publication date: October 21, 2021Inventors: Yuichi TOYAMA, Atsushi MURAI

Patent number: 11078861Abstract: The fuel injection control device and fuel injection control method according to the present invention allow a fuel injection device to perform fuel injection in the case where an open period of the intake valve and an open period of the exhaust valve overlap with each other, and sets the timing to start injection to the closing timing of the exhaust valve, and that sets the timing to end injection to the timing at which a deceleration rate of intake air speed becomes the local maximum. As such, the homogeneity of in-cylinder air-fuel mixture can be improved while preventing the adhesion of fuel to the inner wall of the intake port and the blow-through of fuel to the exhaust passage from occurring.Type: GrantFiled: March 12, 2019Date of Patent: August 3, 2021Assignee: Hitachi Astemo, Ltd.Inventors: Kohsuke Kanda, Atsushi Murai, Yoshitatsu Nakamura

Patent number: 10865696Abstract: The cooling device according to the present invention includes an electric water pump for circulating cooling water through an internal combustion engine of a vehicle, and controls the discharge flow rate of the electric water pump as follows. Until the cooling water temperature. TW reaches a warm-up completion determination temperature, the cooling device increases the discharge flow rate along with an increase of the cooling water temperature TW. After the cooling water temperature TW reaches the warm-up completion determination temperature, the cooling device controls the discharge flow rate so as to bring the combustion chamber wall temperature TCYL toward a target temperature. Thereby, the cooling device can warm up the internal combustion engine more efficiently, and improve the combustion performance of the internal combustion engine after the completion of warm-up.Type: GrantFiled: June 14, 2017Date of Patent: December 15, 2020Assignee: Hitachi Automotive Systems, Ltd.Inventors: Atsushi Murai, Shigeyuki Sakaguchi, Yuichi Toyama

Patent number: 10605150Abstract: The present invention provides a cooling device for an internal combustion engine of a vehicle. While the vehicle is in a decelerating state and while the internal combustion engine is in an idle reduction state, the cooling device increases the ratio of the cooling water circulation rate through a first path which extends through a heater core and a radiator while reducing the ratio of the cooling water circulation rate through a second path which bypasses the heater core and radiator. In addition, the cooling device increases the discharge flow rate of the electric water pump while the vehicle is in a decelerating state, and maintains the electric water pump in an operating state during idle reduction. Thus, the present invention allows accelerating the temperature decrease of the cylinder head during idle reduction, as well as improving fuel economy during acceleration when the vehicle is started.Type: GrantFiled: January 5, 2017Date of Patent: March 31, 2020Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Yuichi Toyama, Atsushi Murai, Shigeyuki Sakaguchi
