Control system for a direct injection-spark ignition engine |
摘要 |
An engine control system for a direct injection-spark ignition type of engine which is equipped with a fuel injector for spraying fuel directly into a combustion chamber, an exhaust system having a lean NOx conversion catalyst for lowering an emission level of nitrogen oxides (NOx) in exhaust gas and an exhaust gas recirculation system divides a given amount of fuel into two parts which are intermittently delivered through early and late split injection respectively in a intake stroke and controls a fuel injector such that a midpoint between points at which the early and late split injection are timed respectively to start is before a midpoint of a intake stroke and the exhaust gas recirculation system admits exhaust gas partly into an intake air stream while the engine is in a lean homogeneous charge zone.
