近几年来在一些小型柴油机上(如LR100/105、ZH1100W、ZH1105W、ZS1105、TY1110、ZS1110等机型),使用直喷式燃烧室。所谓直喷式燃烧室是指由气缸盖底面、活塞顶面和气缸壁面所构成的燃烧室为单一的空间,没有主、副燃烧室之分,喷油器直接把柴油喷在该容积内。活塞顶大多做成W形或ω形凹坑,气缸盖底面为平面,喷油器的轴线与气缸中心线重合或呈一定的角
In recent years in some small diesel engines (such as LR100 / 105, ZH1100W, ZH1105W, ZS1105, TY1110, ZS1110 and other models), the use of direct injection combustion chamber. The so-called direct injection combustion chamber means the combustion chamber composed of the bottom surface of the cylinder head, the top surface of the piston and the wall of the cylinder is a single space. There is no branch between the main combustion chamber and the auxiliary combustion chamber. The injector injects the diesel directly into the volume. Most of the top of the piston made of W-shaped or ω-shaped pit, cylinder head bottom plane, injector axis coincides with the center line of the cylinder or a certain angle
