摘要
There is described a method of controlling the combustion of a direct-injection diesel engine having a common-rail injection system. The control method includes the steps of performing, at each engine cycle and in each cylinder of the engine, a first main fuel injection around the end-of-compression top dead center position, and at least one of a first auxiliary fuel injection preceding the first main injection, and a second auxiliary fuel injection following the first main injection. More specifically, the two auxiliary injections are performed close enough to the first main injection to take part, together with the first main injection, in the actual combustion of the fuel, so as to reduce the pollutant substances present in the exhaust gases, and the combustion noise produced by the engine.
