摘要：The invention concerns a process for the operation of a slow-running multi-cylinder diesel engine, in which a first mean rpm value n &cir& NOt , averaged over

virtually the whole of the engine cycle, is determined, as well as a second mean rpm valuen alpha averaged only over a sector of the cycle corresponding to the distance betweentwo top dead centres. This sector is staggered by an rpm-dependent angle with respectto the top dead centre. The difference n* - n &cir& NOt in rpm is controlled by a slow-acting controller and the difference n*-n alpha is controlled by a quick-acting controller.Both controllers act on the fuel-injection parameters. The slow-acting controllerproduces only small changes in fuel admission while the quick-acting controller enablesaction to be taken rapidly in the event of a fault occurring.
