Title
(EN) INJECTION DEVICE FOR STRATIFIED INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF D'INJECTION POUR MOTEUR À COMBUSTION INTERNE STRATIFIÉ
(ZH) 分层内燃机的喷射装置
Abstract
(EN)
An injection device for a stratified internal combustion engine, comprising two air inlet pipes, at least one air cylinder, a flow stratification device and a fuel injector, the two air inlet pipes being respectively a high oxygen content air inlet pipe and a low oxygen content air inlet pipe; the flow stratification device is arranged between the high oxygen content air inlet pipe and the low oxygen content air inlet pipe and the air cylinder, and the flow stratification device enables high oxygen content gas and low oxygen content gas entering the air cylinder to be axially or transversely stratified in the air cylinder, and the fuel injector injects fuel into the low oxygen content gas. The device realizes the simultaneous reduction of nitrogen oxide and carbon black emission generated by the injected fuel, and there is no or little reduction in combustion efficiency.
(FR)
La présente invention concerne un dispositif d'injection pour un moteur à combustion interne stratifié, comprenant deux tuyaux d'entrée d'air, au moins un cylindre à air, un dispositif de stratification d'écoulement et un injecteur de carburant, les deux tuyaux d'entrée d'air étant respectivement un tuyau d'entrée d'air à haute teneur en oxygène et un tuyau d'entrée d'air à faible teneur en oxygène ; le dispositif de stratification d'écoulement est disposé entre le tuyau d'entrée d'air à haute teneur en oxygène et le tuyau d'entrée d'air à faible teneur en oxygène et le cylindre à air, et le dispositif de stratification d'écoulement permet à un gaz à haute teneur en oxygène et à un gaz à faible teneur en oxygène entrant dans le cylindre à air d'être stratifié axialement ou transversalement dans le cylindre à air, et l'injecteur de carburant injecte du carburant dans le gaz à faible teneur en oxygène. Le dispositif réalise la réduction simultanée des émissions d'oxyde d'azote et de noir de carbone générées par le carburant injecté, et il n'y a pas ou peu de réduction de l'efficacité de combustion.
