摘要
A method of controlling an internal combustion engine (10) of a motor vehicle, wherein the engine (10) is capable of injecting fuel into the cylinder (30) several times during a cycle, characterized in that the method comprises: operating the engine (10) in at least two modes, including a first mode wherein at least exhaust gas recirculation is used to reduce NOx emissions, said at least two modes also including a second mode, said second mode having at least first and second fuel injections per cycle which are supplied to the cylinder (30), and dynamically selecting between at least said first and second modes during vehicle operation based on a prediction of NOx exiting the engine (10).
