摘要
Disclosed is a method of controlling the air fuel mixture of an internal combustion engine following a cold restart. The method comprises determining a control parameter based on the measured or modelled input parameters of the value of current coolant temperature at the time of the engine start, the value of the coolant temperature at the time of the previous engine start, a calibratable reference temperature, the total accumulated fuel mass injected during the previous engine run time, the time the engine was off before the restart and the time the engine was run after previous start. The method then controls the air fuel mixture based on the control parameter. The invention enables adjustment the air fuel mix supplied to the internal combustion engine to allow for the colder temperature of the engine at and immediately following cold start of the engine.
