Gotoh Masato, Katoh Kenji, Asanuma Takamitsu: An exhaust gas purification device for an internal combustion engine. Toyota Motor, October 7, 1998: EP0869267-A2 (13 worldwide citation)

The exhaust gas purification device includes a NOx absorbent disposed in an exhaust gas passage of an internal combustion engine. The engine is mainly operated at a lean air-fuel ratio. The NOx absorbent absorbs NOx in the exhaust gas from the engine when the exhaust gas flowing into the NOx absorbe ...

First combustion mode and second combustion mode are selectively performed. During the first combustion mode, a combustion chamber contains EGR gas of an amount larger than an amount where a generation amount of soot reaches its peak, so that soot is hardly generated. During the second combustion mo ...

Gotoh Masato, Sasaki Shizuo, Yoshizaki Kouji, Ito Takekazu, Murata Hiroki: Internal combustion engine system. Toyota Motor, April 12, 2000: EP0992668-A2 (8 worldwide citation)

An internal combustion engine system is capable of reducing soot and NOx simultaneously, and prevents the occurrence of an undesirable situation where a generation amount of soot is increased in accordance with frequent transitions between a first combustion mode and a second combustion mode. In the ...

Yoshizaki Kouji, Sasaki Shizuo, Gotoh Masato, Ito Takekazu, Murata Hiroki: Internal combustion engine. Toyota Motor, May 17, 2000: EP1001154-A2 (8 worldwide citation)

First combustion and second combustion are selectively switched. During the first combustion, a combustion chamber (5) contains inactive gas of an amount larger than an amount where a generation amount of soot reaches its peak, so that soot is hardly generated. During the second combustion, the comb ...

In a fuel injection control system, a throttle valve is provided on the intake air passage of a diesel engine and an EGR control valve is provided for recycling a part of the engine exhaust gas to the intake air system of the engine. An engine control unit (ECU) controls the intake air amount of the ...

Sasaki Shizuo, Yoshizaki Kouji, Gotoh Masato, Ito Takekazu: Internal combustion engine and method for recirculating exhaust gas. Toyota Motor, January 2, 2002: EP1167727-A2 (7 worldwide citation)

An internal combustion engine performs a second mode of combustion where the EGR is less than the EGR gas that peaks the production of soot. The engine then performs a first mode of combustion where the EGR is greater than the EGR that peaks the production of soot. During the second mode, the engine ...
