CA 2336910

An internal combustion engine, wherein a fuel injection valve (6) and an ignition plug (7) are disposed in a combustion chamber (5), fuel is injected from the fuel injection valve (6) at the end of a compression stroke, the amount of soot produced reaches a peak when the amount of EGR gas is increased and, when the amount of EGR gas is increased further, to the contrary, no soot is produced, whereby, because the amount of EGR gas in the combustion chamber (5) is increased over that produced when the amount of soot produced reaches a peak, the production of soot in the combustion chamber (5) is suppressed.

L'invention concerne un moteur à combustion interne, dans lequel une soupape d'injection de carburant (6) et une bougie d'allumage (7) sont disposées dans une chambre de combustion (5), le carburant étant injecté à la fin d'une course de compression depuis ladite soupape d'injection de carburant (6). La quantité de suie produite atteint son maximum lorsque la proportion de gaz EGR augmente, alors qu'une progression de cette proportion de gaz EGR ne produit pas de suie. En effet, la proportion de gaz EGR dans ladite chambre de combustion (5) est plus importante lorsque la quantité de suie produite est à son maximum, ce qui empêche toute production de suie dans cette chambre de combustion (5).
