Patent number: 7814743Abstract: In an engine 5 including an in-cylinder injector, the valve timing of an intake valve is retarded by VVT (Variable Valve Timing) controlled by an engine ECU to decompress in a combustion chamber at engine startup. In accordance with a configuration in which the valve timing of intake valve is advanced in a stepped manner from an initial set value, fuel injection from in-cylinder injector is inhibited during the time when the advance is equal to or below a predetermined standard value, and fuel injection from in-cylinder injector is allowed when exceeding the predetermined standard value, whereby degradation in the exhaust emission level in accordance with start time decompression control can be suppressed.Type: GrantFiled: January 25, 2006Date of Patent: October 19, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshio Inoue, Tsukasa Abe, Shunsuke Fushiki, Mamoru Tomatsuri, Daigo Ando, Keiko Hasegawa, Osamu Harada, Katsuhiko Yamaguchi, Keita Fukui, Yukihiro Sonoda, Koji Morita, Takuji Matsubara, Yusuke Nakayama

Publication number: 20100037860Abstract: In a predetermined low-temperature startup state (in a rich atmosphere), in principle, over-advanced ignition control for advancing ignition timing beyond MBT and intake-synchronized injection control for causing the entire amount of to-be-injected fuel to undergo intake-synchronized injection are executed. Thus, the peak of intra-cylinder temperature increases, and the amount of port-adhering fuel decreases, whereby the emission amount of unburnt HC can be reduced. However, when the PM emission amount exceeds a PM permissible amount, instead of the intake-synchronized injection control, there is performed processing for causing a portion of the to-be-injected fuel to undergo intake-unsynchronized injection and causing the remaining fuel to undergo intake-synchronized injection. Thus, the amount of intra-cylinder-adhering fuel decreases, and the partial oxidation reaction of the intra-cylinder-adhering fuel, which is a cause of generation of PM, is suppressed.Type: ApplicationFiled: February 15, 2008Publication date: February 18, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koji Morita, Yusuke Nakayama
