Abstract

A fuel injector flow detection device is used for detecting the flow of fuel sprayed out of fuel injectors and comprises a sample conveying unit, a fuel supply unit and a collecting and weighing unit, wherein the sample conveying unit is used for conveying fuel injector samples to a preset detection position; the fuel supply unit is fixedly arranged on a sample feeding unit and moves up and down to make contact with the fuel injector samples which are conveyed to the preset detection position so as to supply the fuel to the fuel injector samples and trigger the fuel injectors to spray out the fuel; and the collecting and weighing unit is arranged at the positions, corresponding to the fuel supply unit, below the sample conveying unit and used for collecting the fuel sprayed out of the fuel injector samples and measuring the weight of the fuel. An electronic oil injector flow tester comprises a rack and a detection device which is arranged on the rack, wherein the rack is any fuel injector flow detection device.

Description

technical field [0001] The invention relates to a detection device and a tester for detecting the flow rate of a fuel injector, which belong to the field of automation. Background technique [0002] The fuel injector is a key component in the gasoline injection system for accurately metering fuel and forming spray. The electronic control unit adjusts the fuel supply of the engine by controlling the fuel injection time of the fuel injector, and further precisely controls the air-fuel ratio. The flow characteristics of the injector directly affect the fuel injection effect, and have a direct impact on the matching of the gasoline engine and the electronic control system and the performance of the electronic control engine. Therefore, the flow consistency of all products must be ensured during the production process. [0003] In the past, the flow test of the injector in the production process was completely completed by manual operation, which was labor-intensive and low in p...
