Abstract

The invention provides a performance detection system for an automotive electronic fuel pump, which comprises a fixture for being connected with a machine frame and an industrial PC (Personal Computer) and performance analysis and test software arranged in the machine frame,wherein the PC and performance analysis and test software is connected with an analog signal conditioning module, a power amplifying module and a proportional control module through an embedded USB (Universal Serial Bus) interface synchronous data acquisition device; the analog signal conditioning module is connected with a pressure sensor, a flow sensor, a current sensor and a voltage sensor; the power amplifying module controls a solenoid valve driving control; the proportional control module is connected with a system pressure regulator and a system voltage regulator; and the proportional control module controls a system oil line. Through the system, the test and the analysis of oil pump pressure flow characteristic, current flow characteristic and pressure current characteristic of the automotive fuel pump can be realized,so that the performance of the automotive fuel pump is evaluated.

Description

【Technical field】 [0001] The invention relates to a detection system, in particular to a performance detection system applied to automobile fuel pumps. 【Background technique】 [0002] Automotive electronic fuel pump is a new industry. Before 2001, the Chinese market did not need this product, because the Chinese government wanted to improve environmental protection in 2001. Mandatory for all cars to be electronically injected. So the era of carburetors in China is over. As a major component of the automotive EFI system, the function of the electronic fuel pump is to deliver the fuel stored in the fuel tank to the fuel line of the injector. It should be known that the fuel system must maintain a certain pressure, only in this way can the fuel sprayed by the injector be better atomized and combustible. But when the engine is turned off, the pressure of the fuel system will be lost. Once there is no residual pressure, it is easy to generate air lock in the pipeline at high ...
