Problems solved by technology

In the design state of the existing technology, the horizontal component force Fh is transmitted to the injector through the injector pressure plate. As a result of the long-term action of this force, it will cause partial wear of the injector parts, which will affect the reliability of the injector. , resulting in the engine not working properly

Abstract

The invention discloses a fixed device for a motor fuel injector and the motor with the device and the fixed device of the injector comprises an injector press plate and an injector fixed screw, wherein the injector fixed screw fixes the injector on a cylinder lid of the motor via the injector press plate, characterized in that the device also comprises a press plate heel block which is arranged below the injector press plate and on a cap of a cylinder screw, and the dip angle between the press plate heel block and the contact face of the injector press plate is same to the assembling angle ofthe injector. The invention delivers the horizontal force of the injector press plate as being pressed to the cylinder lid screw to make the cylinder lid screw bearing the force, therefore the injector only can bear the down packing force without any horizontal force, thereby eliminating grinder phenomenon of coupling parts in the injector.

Description

technical field [0001] The invention relates to a fixing device for a fuel injector of an automobile engine, in particular to a fixing device capable of eliminating eccentric wear of a pair of fuel injectors of an automobile engine. Background technique [0002] The engine injector is installed on the engine cylinder head, and its injection end extends into the engine combustion chamber, and the maximum pressure in the combustion chamber can reach more than 120 bar. Therefore, in order to ensure sealing, the fuel injector needs to be fastened on the cylinder head of the engine with bolts. For the fixing device of the fuel injector of the engine, the existing technology simply considers the fixing function, but does not pay attention to the stress of the fuel injector under the condition of bolt fastening, especially does not consider the force of the fuel injector assembly. For example, the Chinese Patent Publication No. is the comparative document of CN1158384, which discl...
