Abstract | A cylinder injection type spark ignition engine enabling a stratified combustion with high robustness without relying upon tumbling generated in a combustion chamber, comprising a fuel injection nozzle (9) directly injecting fuel into the combustion chamber (4), wherein the fuel injection nozzle injects fuel into the combustion chamber during compression stroke and the mixture is ignited by a spark plug (10) to provide the stratified combustion, the fuel injection nozzle (9) generates, separately from air flow supplied through an intake port to the combustion chamber, lead spray (13) supplied toward the spark plug prior to the subsequent fuel spray for ignition (14), and the mixture evaporated from the fuel spray for ignition at the time of ignition is fed to the spark plug by the lead of the lead spray (13).
L'invention concerne un moteur à allumage par étincelle du type à injection directe, autorisant une combustion stratifiée présentant une bonne performance, et ne dépendant pas des tourbillons générées dans la chambre de combustion. Ce moteur comprend un injecteur (9) de carburant qui injecte directement le carburant dans la chambre (4) de combustion. Cet injecteur injecte le carburant dans la chambre de combustion pendant la course de compression et le mélange est allumé par une bougie d'allumage afin de produire une combustion stratifiée. L'injecteur (9) produit, séparément du flux d'air entrant dans la chambre de combustion par un orifice d'admission, un jet (13) pilote dirigé vers la bougie, avant d'émettre le jet (14) de carburant destiné à l'allumage, et le mélange évaporé du jet de carburant d'allumage au moment de l'allumage est guidé vers la bougie par le jet (13) pilote. |
