Fuel injector structure of two-stroke horizontal opposed-piston and opposed-cylinder engine

一种二冲程水平对置活塞、对置气缸发动机的喷油器结构

Abstract

The utility model discloses a fuel injector structure of a two-stroke horizontal opposed-piston and opposed-cylinder engine. The fuel injector structure comprises an engine body and two fuel injectors, wherein two mounting holes and a cylinder hole are formed in the engine body, and the axis where the two mounting holes are located directly face a combustion chamber in the cylinder hole; the two fuel injectors are respectively mounted in the two mounting holes. The fuel injector structure of the two-stroke horizontal opposed-piston and opposed-cylinder engine has the advantages that the two fuel injectors are disposed in the combustion chamber, fuel can be well mixed with air in the combustion chamber after being injected by the two fuel injectors, and accordingly combustion is improved, and the performance index, economic index and emission of the engine are improved; meanwhile, due to the fact that the two fuel injectors are disposed in each combustion chamber, the two fuel injectors can inject fuel synchronously or asynchronously, multiple injections of fuel in a cylinder can be effectively achieved, and flexible fuel injection control strategies can be achieved.
本实用新型公开一种二冲程水平对置活塞、对置气缸发动机的喷油器结构,其中,包括一发动机机体,所述发动机机体上开设两安装孔和一缸孔,并且两所述安装孔所在的轴线正对所述缸孔内的燃烧室;两喷油器,两所述喷油器分别安装在两所述安装孔中。使用本实用新型一种二冲程水平对置活塞、对置气缸发动机的喷油器结构,在燃烧室配有两喷油器,使得燃油由两喷油器喷出后,在燃烧室内与新鲜空气充分混合,从而改善燃烧,使发动机性能指标,经济指标和排放得到改善。同时,由于每个燃烧室配有两喷油器,两喷油器可以实现同时或不同时喷油,有效地实现缸内燃油多次喷射的同时,喷油控制策略可以更加灵活。
