摘要: An exhaust gas purification system has a first accumulation quantity estimation device that estimates an of particulate matters collected by diesel filter (DPF) based on flowing state and second the operating engine. The is employed only when flow rate equal to or greater than predetermined value engine in steady state. Otherwise, employed. increased if continues for long time. Thus, opportunity perform with increased, accuracy improved.
