Abstract

L'invention concerne un mode de fonctionnement d'un moteur diesel à l'aide d'une émulsion, selon lequel le moteur diesel est éventuellement piloté à l'aide d'une émulsion d'eau dans le carburant diesel, produite en amont de la pompe d'injection du moteur diesel ou à l'aide de carburant diesel exempt d'eau. Lorsqu'il tourne à bas régime et qu'il est peu sollicité, ce moteur diesel fonctionne à l'aide de carburant diesel. Lorsqu'il tourne à haut régime et qu'il est très sollicité, ce moteur diesel fonctionne à l'aide d'une émulsion. Une petite réserve de carburant diesel pur et une autre petite réserve d'émulsion se trouvent à proximité de l'arrivée de la pompe d'injection. Lorsque le moteur diesel passe du mode de fonctionnement à l'aide de l'émulsion au mode de fonctionnement à l'aide de carburant diesel et inversement, la pompe est rincée au moins à l'aide d'une partie de la réserve de carburant diesel ou de la réserve d'émulsion. La réserve d'émulsion se trouve de ce fait complétée par l'émulsion résiduelle provenant du reflux de la pompe d'injection, lors du rinçage à l'aide de carburant diesel, et la réserve de carburant diesel se trouve complétée par le carburant diesel résiduel provenant du reflux de la pompe d'injection, lors du rinçage à l'aide de l'émulsion.
