Title
(EN) GASOLINE ENGINE AND COMBUSTION CONTROL METHOD THEREFOR
(FR) MOTEUR À ESSENCE ET MÉTHODE DE CONTRÔLE DE LA COMBUSTION
(ZH) 一种汽油发动机及其燃烧控制方法
Abstract
(EN)
A gasoline engine and a combustion control method therefor. The gasoline engine comprises a cylinder cover (22); the cylinder cover (22) is provided with a gas inlet passage (19), an exhaust passage (21), a backflow passage (20), and an exhaust gas recirculation pipeline (14); the gas inlet passage (19) is connected to a gas inlet pipe (1) of the engine, and comprises an axial gas passage is provided in a top center region of an engine combustion chamber (10); the backflow passage (20) comprises a tangential gas passage tangent to a cylinder wall of the engine; exhaust gas discharged from the exhaust passage (21) flows back to the backflow passage (20) by means of the exhaust gas recirculation pipeline (14). The gasoline engine enables the interior of a cylinder to form columnar partitioned gas distribution in which the center is a fresh mixed gas combustion zone, and the periphery is exhaust gas, thereby reducing the heat dissipation loss of the engine and improving the thermal efficiency.

L'invention concerne un moteur à essence et une méthode de contrôle de la combustion. Le moteur à essence comprend un couvercle de cylindre (22); le couvercle de cylindre (22) est pourvu d'un passage d'entrée de gaz (19), d'un passage d'échappement (21), d'un passage de reflux (20) et d'une conduite de recirculation des gaz d'échappement (14); le passage d'entrée de gaz (19) est relié à un tuyau d'entrée de gaz (1) du moteur, et comprend un passage axial de gaz disposé dans une région centrale supérieure d'une chambre de combustion de moteur (10); le passage de reflux (20) comprend un passage de gaz tangentiel tangent à une paroi de cylindre du moteur; les gaz d'échappement évacués du passage d'échappement (21) s'écoule en retour vers le passage de reflux (20) au moyen de la conduite de recirculation des gaz d'échappement (14). Le moteur à essence permet à l'intérieur d'un cylindre de former une distribution de gaz cloisonnée en colonne dans laquelle le centre est une zone de combustion de gaz mixte frais, et la périphérie estconstituée de gaz d'échappement, ce qui permet de réduire la perte de dissipation de chaleur du moteur et d'améliorer l'efficacité thermique.
