Engine oil sprayer base connecting system

Abstract

The invention discloses an engine oil sprayer base connecting system. An oil sprayer is hermetically connected and fixed with a cylinder cover by using a large bolt through an oil sprayer pressure plate on an oil sprayer base; meanwhile, the oil sprayer base is connected and fixed with the cylinder cover through the large bolt; the cylinder cover is provided with hollow cavities of which the appearances are the same as those of oil sprayer bases according to the quantity of the oil sprayers; the oil sprayer base is connected and fixed with the cylinder cover through three small bolts; a high-pressure oil pipe which is connected with the oil sprayer, a small oil return pipe and an electric control wiring harness are arranged outside the cylinder cover; and the oil sprayer base is sealed together with the cylinder cover through a sealing rubber ring. The oil sprayer is fixed skillfully through a reasonable design, and meanwhile, the high-pressure oil pipe which is connected with the oil sprayer, the small oil return pipe and the electric control wiring harness are arranged outside the cylinder cover, so that great convenience is brought to assembly of the entire machine and after-sale service on the basis of effectively reducing the height of the cylinder cover, and the maintaining cost is lowered.

Description

technical field

[0001] The invention belongs to engine components, in particular to an engine fuel injector seat connection system. Background technique

[0002] As we all know, all countries in the world attach great importance to environmental protection, so the emission standards for motor vehicle exhaust are becoming increasingly strict. It is not a long-term solution to improve the exhaust emission standards of two-valve engines through technological improvement, so the production of four-valve engines will become the focus of manufacturers. . As an important part of the diesel engine, the fuel injector is generally installed upright in the middle of the cylinder head and covered with a cylinder head cover. The fuel injector will be connected with the high-pressure oil pipe, the small oil return pipe, and the electric control wiring harness of the fuel injector. Due to the large number of components, its installation and maintenance are very inconvenient, and it also i...
