Abstract

The invention relates to the technical field of automobile engines, in particular to an installation device for an automobile engine fuel injector, which solves the disadvantages of existing percussion installations that affect the installation quality of the fuel injector, and includes a device housing whose two sides are welded There is an auxiliary handle, the bottom inside of the device housing is clamped with an active rotating rod through bearings, and the inside of the device housing is also clamped with a transmission rod through bearings. The outer bottom of the transmission rod is provided with a pressure spring, and the transmission rod The outer side of the bottom of the horizontal pressure plate is also sleeved with a horizontal pressure plate, and the middle of the horizontal pressure plate is sleeved with an expansion rod. The expansion rod is located on the top of the horizontal pressure plate. , The installation of the fuel injector does not need to be knocked, and it is not easy to shift and deform, which improves the installation quality and is more convenient during the installation process. It can be realized by twisting with a Phillips screwdriver, which is very convenient.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to an installation device for an automobile engine fuel injector. Background technique [0002] The fuel injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The fuel injector receives the fuel injection pulse signal sent by the ECU to precisely control the fuel injection quantity. [0003] Chinese patent application number: CN200420039171.7 discloses a device for installing the bushing of the fuel injector of an automobile engine. The device installs the bushing of the fuel injector by knocking. Shifting, and there is also the situation that the top of the bushing is deformed, which affects the installation quality of the injector. Contents of the invention [0004] The object of the present invention is to solve the shortcom...
