Patent number: 9897022Abstract: An engine includes a turbocharger, an air bypass valve, a wastegate valve, and an EGR apparatus. The engine also includes an ISC passage that connects an upstream side and a downstream side of a throttle valve in an intake passage, and an ISC valve that adjusts an amount of air flowing through the ISC passage. A control apparatus for the engine performs valve opening control to set an opening of an ISC valve at a larger opening than a reference opening when a required torque required by the engine is smaller than an estimated torque that can be generated by the engine, and closes the air bypass valve and the wastegate valve for a fixed period following completion of the valve opening control when an EGR valve of a low pressure EGR apparatus is opened during execution of the valve opening control.Type: GrantFiled: January 8, 2014Date of Patent: February 20, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yasuhiro Kuze

Patent number: 9890718Abstract: A control apparatus for an internal combustion engine of this invention includes: a turbo-supercharger; an exhaust gas purifying catalyst disposed in an exhaust passage on the downstream side of a turbine; and a WGV capable of opening and closing an exhaust bypass passage that bypasses the turbine. At the time of a catalyst warm-up request, catalyst warm-up control that opens the WGV and retards the ignition timing is executed. If the sensitivity of control of an intake air amount by a throttle valve is high, the intake air amount is controlled using the throttle valve during execution of the catalyst warm-up control. If the control sensitivity is low, the intake air amount is controlled using the WGV during execution of the catalyst warm-up control. When the WGV degree of opening is controlled toward a closed side during execution of the intake air amount control using the WGV, a retard amount of the ignition timing is increased.Type: GrantFiled: January 11, 2012Date of Patent: February 13, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takashi Tsunooka

Patent number: 9869237Abstract: A turbocharger includes a two-stage serial compressor having first and second impellers, with a crossover duct for leading air from the first impeller into the second impeller for further compression. The compressor housing also defines a bypass duct from the crossover duct to the air discharge duct from the compressor, and a bypass valve disposed in the bypass duct. Under certain operating conditions (such as high-flow, low-pressure-ratio conditions) the bypass valve can be opened to bypass the second impeller, such that the compressor behaves like a single-stage compressor. At other operating conditions, the bypass valve is closed so that the compressor provides two-stage compression for higher pressure ratios.Type: GrantFiled: August 19, 2015Date of Patent: January 16, 2018Assignee: Honeywell International Inc.Inventors: Vit Houst, Daniel Turecek, Vaclav Kares, Milan Nejedly, Ondrej Lednicky, Michal Mokos, Zbynek Oslejsek

Patent number: 9759165Abstract: An upper-limit threshold value and a lower-limit threshold value of a fore-and-aft differential pressure of an EGR control valve is calculated based on an intake-air quantity detected by an airflow meter. An actual fore-and-aft differential pressure of the EGR control valve is calculated from detected values of an upstream-side pressure sensor and a downstream-side pressure sensor. Then, these threshold values are compared with the actual fore-and-aft differential pressure, and when the actual fore-and-aft differential pressure exceeds the upper-limit threshold value or when the actual fore-and-aft differential pressure is less than the lower-limit threshold value, it is determined that the pressure loss of an intake and exhaust system has changed. If it is determined that the pressure loss of an intake and exhaust system has changed, EGR is inhibited, and if not so, EGR is permitted to be performed. These threshold values are varied depending on a target EGR rate.Type: GrantFiled: May 31, 2013Date of Patent: September 12, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Daisuke Takaki, Hirofumi Tsuchida, Takeshi Tsuyuki
