Patent number: 11885272Abstract: An engine control system according to the present disclosure includes an oil temperature sensor and a waste gate valve control unit. The oil temperature sensor detects a temperature of an engine oil. The waste gate valve control unit controls opening and closing of a waste gate valve based on the temperature of the engine oil detected by the oil temperature sensor. More specifically, when the temperature of the engine oil detected by the oil temperature sensor is equal to or less than a predetermined threshold, the waste gate valve control unit controls the waste gate valve so that it opens.Type: GrantFiled: May 24, 2023Date of Patent: January 30, 2024Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shigeta Kikuchi, Tatsuya Suzuki, Hiroaki Mizoguchi, Toshiaki Otani

Patent number: 10760503Abstract: A controller for an internal combustion engine includes a controlling section that controls a variable valve actuation device such that the phase of an intake valve becomes a target value. The controlling section executes a process of setting the target value to a steady or transient state phase, a process of calculating a load change rate, and a process of setting a change amount of the transient state phase. The change amount of the transient state phase is set to a change amount when the engine operating state is a transient state and the load change rate is greater than or equal to a predetermined threshold. The change amount of the transient state phase is set to a second change amount that is less than the first change amount when the engine operating state is the transient state and the load change rate is less than the threshold.Type: GrantFiled: January 4, 2019Date of Patent: September 1, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Toshiaki Otani

Patent number: 10738719Abstract: A controller for an internal combustion engine defines a difference between a throttle opening degree target value before correction and a throttle opening degree target value after correction as a correction amount. The difference between a downstream pressure that is a pressure downstream of a throttle valve in the intake passage and a required value of the downstream pressure is defined as a pressure difference. The controller corrects the throttle opening degree target value so that the correction amount increases as the absolute value of the pressure difference increases, the correction amount is smaller when the throttle opening degree is large than when the throttle opening degree is small, and the correction amount is smaller when the flow velocity of intake air in the intake passage is low that when the flow velocity of the intake air is high.Type: GrantFiled: January 29, 2019Date of Patent: August 11, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiro Wanibe, Toshiaki Otani

Patent number: 7772568Abstract: An object of the present invention is to extract a micro foreign body of a few ?m, which may cause a product defect of a device or the like, and to subject the foreign body to a mass analysis at a favorable S/N ratio without any contamination. A micro sample heating probe includes a sample holder made up of two members different in diameter, a supporting part, and a terminal part. The sample holder includes a heating mechanism only in a limited part, and just a region extremely close to the micro sample being an analysis target is heated locally. Therefore, even when a contaminated substance is attached to the probe, such substance is not heated, thereby preventing a noise from occurring, and enabling an analysis at a quite favorable S/N ratio.Type: GrantFiled: September 5, 2008Date of Patent: August 10, 2010Assignee: Hitachi, Ltd.Inventors: Kazuhiko Horikoshi, Naotoshi Akamatsu, Toshiaki Otani
