Abstract

Viene descritto un procedimento per il controllo del carico di un motore a combustione interna a quattro tempi a compressione di miscela, il cui scambio di gas viene controllato da almeno una valvola di ammissione e una valvola di scarico. In questo procedimento, il momento di chiusura della valvola di ammissione viene spostato, in presenza di carico decrescente, in direzione "presto". Per ottenere, specialmente nel limite di carico parziale minore e medio, una riduzione dell'emissione di veleni viene proposto di aprire, in questi limiti di carico dopo il decorso di un determinato lasso di tempo dopo la chiusura della valvola di ammissione, brevemente la valvola di scarico.A method is described for controlling the load of a four stroke internal combustion engine with mixture compression, the gas exchange of which is controlled by at least one admission valve and one exhaust valve. In this procedure, the closing moment of the admission valve is shifted, in the presence of decreasing load, in the "early" direction. To obtain, especially in the lower and medium partial load limit, a reduction in the emission of poisons is proposed to open, in these load limits after the elapsing of a certain period of time after the closing of the admission valve, briefly the valve of discharge.
