Patent number: 10970601Abstract: In the intermediate process state estimation method, two generators are used, and as well as inputting a common input noise to the respective generators, a label corresponding to a certain step is input to one generator and a label corresponding to a step different from the certain step is input to the other generator. Then, one of generation data and training data generated by the respective generators is randomly input to a discriminator, and the generators and the discriminator learn in an adversarial manner from the discrimination result in the discriminator. Then, an input noise corresponding to a desired final state and a label corresponding to a step where it is desired that an intermediate process state be estimated are input to the learned generator to estimate the intermediate process state based on the generation data generated by the generator.Type: GrantFiled: May 1, 2019Date of Patent: April 6, 2021Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, TOYOTA SCHOOL FOUNDATIONInventors: Tetsuya Kajimoto, Yutaka Sasaki, Makoto Miwa, Yuta Hayashida

Patent number: 8850877Abstract: In a reforming driving mode, while the EGR valve is opened to recirculate a part of exhaust gas into the intake pipe, a reforming-fuel injector injects a reforming-fuel into an exhaust gas flowing through an EGR pipe. The injected reforming-fuel is vaporized and flows into the fuel-reforming catalyst. The fuel-reforming catalyst reforms the fuel in the exhaust gas into the fuel having high combustibility. In the reforming driving mode, the computer determines whether an air-fuel ratio within the normal range. Based on this result, the computer determines whether the reforming-fuel injector has a malfunction. When the reforming-fuel injector has a malfunction, a fail-safe processing is conducted to prohibit the reforming-fuel injector from injecting the reforming-fuel.Type: GrantFiled: June 6, 2012Date of Patent: October 7, 2014Assignee: Denso CorporationInventors: Hiroyuki Inuzuka, Makoto Miwa

Patent number: 8712670Abstract: When a driving region of an engine is in a specified self-ignited combustion region, a valve timing is controlled in such a manner as to establish a negative valve overlap period in which an exhaust valve and an intake valve are closed. During the negative valve overlap period, a direct injection is performed to reform a fuel. After the direct injection, a port injection is performed to control an output. Thereby, a self-ignited combustion control is performed. During the self-ignited combustion control, a fuel reform degree of the fuel injected by the direct fuel injection is detected, and a self-ignited combustion condition in a present combustion cycle is estimated based on the fuel reform degree detected in the present combustion cycle. A fuel injection quantity of the intake port fuel injection is corrected according to the estimated self-ignited combustion condition in order to stabilize the self-ignited combustion condition.Type: GrantFiled: December 23, 2009Date of Patent: April 29, 2014Assignee: Denso CorporationInventors: Masahiro Shigenaga, Kimitaka Saitoh, Masatoshi Basaki, Kiyohiko Watanabe, Makoto Miwa

Patent number: 8478508Abstract: An ON-ignition signal is outputted from an ignition control portion in a period from a posterior time point of the power stroke to an valve opening timing of an exhaust valve so that a capacitor is charged. Then, when it is determined that the maximum value of an ion-output value detected during a negative valve overlap period becomes greater than or equal to a threshold, it is determined that the applied voltage between an center electrode and a ground electrode of a spark plug is dropped. The ON-ignition signal is outputted again to charge the capacitor before the intake valve is opened.Type: GrantFiled: July 22, 2010Date of Patent: July 2, 2013Assignees: Nippon Soken, Inc., Denso CorporationInventors: Masahiro Shigenaga, Kimitaka Saitoh, Masatoshi Basaki, Makoto Miwa

Publication number: 20120291424Abstract: A diagnostic apparatus for a catalyst in a fuel-property reforming system includes an inlet-side temperature sensor disposed upstream of the fuel-reforming catalyst and an outlet-side temperature sensor disposed downstream of the fuel-reforming catalyst. In a reforming driving mode, while the EGR valve is opened to recirculate a part of exhaust gas into the intake pipe, a reforming-fuel injector injects a reforming fuel into the EGR gas. A fuel-reforming catalyst reforms the fuel into a fuel having high-combustibility. A differential temperature between a temperature detected by the inlet-side temperature sensor and a temperature detected by the outlet-side temperature sensor is compared with a deterioration-determination threshold, whereby a computer determines whether the fuel-reforming catalyst is deteriorated.Type: ApplicationFiled: May 18, 2012Publication date: November 22, 2012Applicant: DENSO CORPORATIONInventors: Hiroyuki INUZUKA, Makoto MIWA

Publication number: 20120285400Abstract: An ECU computes a quantity of reforming-fuel which the reforming-fuel injector injects based on an engine driving condition and an EGR quantity. The injecting quantity of the reforming-fuel is properly adjusted according to an EGR gas temperature or an alcohol concentration of the reforming-fuel, whereby it can be restricted that temperature of a fuel-reforming catalyst and the EGR gas temperature are decreased due to a vaporization heat of the reforming-fuel. Also, an injecting time period of the reforming-fuel is properly adjusted, so that a maldistribution of the reforming-fuel is restricted. Furthermore, an injection cycle of the reforming-fuel is varies according to an engine speed, so that a supplied quantity of the reforming-fuel is made uniform for each cylinder.Type: ApplicationFiled: April 24, 2012Publication date: November 15, 2012Applicant: DENSO CORPORATIONInventors: Hiroyuki Inuzuka, Makoto Miwa

Publication number: 20120222407Abstract: A catalyst warming-up controller executes a catalyst warming-up control in which an ignition timing is retarded to warm-up a catalyst and performs a compression-stroke injection in which a fuel is injected into a cylinder in a compression stroke. While the catalyst warming-up control is executed, a variable valve timing controller controls a valve timing of an intake valve and/or an exhaust valve to establish a negative-valve-overlap period in which both of the exhaust valve and the intake valve are closed. A fuel injector injects the fuel into a cylinder in this period and a quantity of the compression-stroke injection is decreasingly corrected according to the injection quantity in the above period.Type: ApplicationFiled: March 2, 2012Publication date: September 6, 2012Applicant: DENSO CORPORATIONInventors: Makoto MIWA, Hiroyuki INUZUKA

Publication number: 20120221225Abstract: When an engine is driven in a compression self-ignited combustion region, a fuel injector injects a fuel into a cylinder in a negative-valve-overlap period where an exhaust valve and an intake valve are both closed. Then, the fuel is injected into the cylinder in an intake stroke. The injected fuel is compressed in a compression stroke to be self-ignited. When it is determined that a steep combustion occurs and a fuel injection quantity in the negative-valve-overlap period is greater than a lower determination threshold, the fuel injection quantity in the negative-valve-overlap period is reduced. When the fuel injection quantity is not greater than the lower determination threshold, an oxygen quantity in the cylinder is reduced.Type: ApplicationFiled: February 23, 2012Publication date: August 30, 2012Applicant: DENSO CORPORATIONInventors: Masahiro SHIGENAGA, Motomasa Iizuka, Masatoshi Basaki, Makoto Miwa

Publication number: 20110307163Abstract: A controller performs compression self-ignition combustion control for combusting a mixture gas by injecting fuel into a cylinder in a negative valve overlapping period (NVO period), in which both of an exhaust valve and an intake valve are closed, and by causing self-ignition of the mixture gas using compression in a compression stroke. If knocking is detected during the above control, the controller performs knock suppression control for correcting a fuel injection quantity in the NVO period to suppress the knocking. If a pressure increase rate of cylinder pressure during the combustion is lower than a threshold value, the controller performs increase correction of the fuel injection quantity in the NVO period. If the pressure increase rate is equal to or higher than the threshold value, the controller performs decrease correction of the fuel injection quantity in the NVO period.Type: ApplicationFiled: June 15, 2011Publication date: December 15, 2011Applicants: NIPPON SOKEN, INC., DENSO CORPORATIONInventors: Takehiko KATO, Masahiro SHIGENAGA, Masatoshi BASAKI, Kimitaka SAITO, Makoto MIWA
