Diesel Injector Fuel Injector 0445120380 compatible with Bosch injector Yuchai Machinery YC6J

The general compromise is. The center line of the combustion chamber in the piston top is between the center line of the cylinder and the projection of the nozzle end on the piston top plane. In this way, there is often a deviation between the installation position of the injector and the center line of the combustion chamber in the top of the piston, and the center line of the two also has an Angle.

In order to process the injector hole in the process of simple, efficient, and reduce the processing error, it is generally hoped that the center line of each hole of the porous nozzle converge on the same conical surface, that is, intersect at the common cone top. The top of the cone usually lands on the injector. Center line. The cone composed of the center line of each jet hole as a bus is called the jet cone.

In the design of jet hole and injection of modern high-speed diesel engine, the principle of "uniform distribution of top jet (close), equal height of main sight drop point, and convergence of holes in the same cone" is often used. The same plane formed by the equal points of each injection on the combustor wall is usually parallel to the bottom plane of the cylinder head. The distance between the plane composed of the landing points (referred to as the landing point plane) and the plane of the living castell (when the piston is at top dead center) depends on the size of the cone Angle of the injection, the form of the mixture (mainly space combustion or oil film combustion), and the airflow in the combustion chamber (including whether there is extrusion eddy current, etc.) and other factors.
