METHOD FOR WARM-UP OF CATALYST OF EXHAUST GAS TREATMENT DEVICE |
摘要 |
A method of controlling an internal combustion engine for warm-up of catalyst of an exhaust gas treatment device is disclosed. The method comprises generating a warm-up demand for heating the catalyst subject to constraint on stable combustion. Based on the warm-up demand, a reduction in excess air ratio is determined. A desired value in excess air ratio is modified by the reduction to provide a modified desired value in excess air ratio. Based on the reduction, a desired value in EGR rate is modified to provide a modified desired value in EGR rate. Based on the modified desired value in EGR rate, an EGR command signal is determined. |
