Patent number: 6968825Abstract: A control device for a spark-ignition engine, in which a mixture in a combustion chamber is fired by compression ignition in a part-load range under warm-running conditions, includes an EGR controller incorporating a valve operation controller for controlling internal EGR of hot burned gas and a cold EGR controller for controlling external EGR of cold burned gas. The EGR controller performs EGR control operation to leave the hot EGR gas in the combustion chamber in a lower-load, lower-speed region within a compression ignition combustion range and to introduce the cold EGR gas into the combustion chamber in a higher-load, higher-speed region within the compression ignition combustion range. The control device further includes a firing assist unit for inducing the compression ignition at least when ignitability of the mixture decreases due to introduction of the cold EGR gas in the compression ignition combustion range.Type: GrantFiled: June 3, 2004Date of Patent: November 29, 2005Assignee: Mazda Motor CorporationInventors: Mitsuo Hitomi, Takayoshi Hayashi, Kouji Sumida, Masahisa Yamakawa, Satoru Matsuzaki, Hiroyuki Maeda
