Publication number: 20120222418Abstract: An internal combustion engine system includes: a turbine disposed in an exhaust passage; a bypass passage provided in the exhaust passage and bypassing the turbine; a wastegate valve that opens and closes the bypass passage; and an air-fuel ratio sensor provided downstream of a discharge port of the bypass passage. The air-fuel ratio sensor is provided at such a position that the proportion of the amount of exhaust gas that directly strikes the air-fuel ratio sensor to the amount of exhaust gas discharged from the bypass passage changes depending on the opening degree of the wastegate valve. When the engine is in a cold-start state, the proportion of the amount of exhaust gas that directly strikes the air-fuel ratio sensor after being discharged from the bypass passage to the amount of exhaust gas discharged from the bypass passage is made smaller than when the engine is in a warm-start state.Type: ApplicationFiled: February 24, 2012Publication date: September 6, 2012Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Junji WATANABE

Publication number: 20120090578Abstract: High pressure regions (31H to 35H) and low pressure regions (31L to 34L) are created based on the exhaust gas flow at curves in an EGR pipe (30), thereby enabling the exhaust gas pressure at inlets (21b to 26b) of gas introduction passages (21a to 26a) to be adjusted. Accordingly, regardless of the number of cylinders or whether the lengths of the flow paths of the EGR pipe (30) are the same, the exhaust pressure at the inlets (21b to 26b) of the gas introduction passages (21a to 26a) can be appropriately adjusted so any difference in pressure of exhaust gas introduced into branch pipes (21 to 26) can be reduced. In this way, the EGR rates of the cylinders can be made closer or the same such that stable combustion can be achieved, thus enabling stable engine operation to be maintained. The EGR pipe (30) is arranged weaving closely between the branch pipes (21 to 26) so space efficiency can be improved and a sufficient amount of exhaust gas can be introduced evenly into the cylinders.Type: ApplicationFiled: November 28, 2008Publication date: April 19, 2012Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Akira Nakawatase, Taketo Nagasaki, Junji Watanabe
