Embodiment Construction

[0013] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0014] see figure 1 , a simple electronically controlled fuel injector test bench, the test system includes a fuel tank 1 for storing test oil, a pressure operating rod 2 for providing pressure for the test oil is installed on the fuel tank 1, and a pressure gauge 3 is installed on the fuel tank 1 for use The installation bracket 5 of the fuel injector 4 is installed. The fuel injector is connected to the fuel tank 1 and the test oil recovery device 6 through the oil pipe 8. The test oil recovery device adopts a recovery device that is more common in the market. The test oil is recovered and reused, and the above-mentioned structure belongs to the main structure of the known fuel injector test bench; the present invention also includes an ele...

Abstract

The invention relates to a simple electronic control testboard, which comprises a fuel tank; a pressure operating rod for providing pressure for test fuel is arranged on the fuel tank; the fuel tank is provided with a pressure gauge and a mounting bracket used for mounting the fuel injector; and the fuel injector is connected with the fuel tank and a test fuel recovery unit through a fuel pipe. The simple electronic control testboard is characterized in that the test system also comprises an electronic control mechanism for controlling the atomization of the fuel injector. By adopting the structure, an operator can operate the pressure operating rod and a motor switch simultaneously, and observes whether the fuel injector injects fuel and the fuel atomizing condition at any time so as to determine whether the fuel injector fails. Therefore, a trouble that the fuel injector is brought to a monitoring station specially is eliminated, and the supplementary cost is reduced. The conventional fuel injector testboard is modified; the modification cost is reduced to the maximum on the premise of not wasting resources, and the simple electronic control testboard is easy to promote and use in various service stations; besides, the simple electronic control testboard can complete tests and obtain test results in short time, so the time and human resource are saved.

Description

technical field [0001] The invention belongs to the technical field of electronic control supply diesel engine manufacturing, in particular to a simple electronic control fuel injector test bench. Background technique [0002] At present, with the increasingly sophisticated diesel engine technology, the use of common rail electronically controlled diesel engines is increasing. However, the detection of electronically controlled fuel injectors has become a difficult problem: to detect electronically controlled fuel injectors, when the oil pressure reaches the specified pressure value, the solenoid valve on the fuel injector needs to be powered by 24V (or 12V) to open the valve , so that the fuel injector sprays the fuel atomized. The inspector confirms the fault point of the fuel injector according to whether the fuel injector is injecting oil and the atomization condition. However, the existing fuel injector testing station can only provide oil pressure, but cannot provide...
