Abstract

The invention relates to an automobile fuel pressure wireless detection device. The invention aims to overcome the defect that the existing fuel pressure test mode is not convenient and safe enough, does not have the function of analysis, and the like in the automobile running process, changes the traditional fuel pressure test mode and separates a fuel pressure signal acquisition processing unit from a signal display operating device (separates a test host computer from a pressure test module); and the fuel pressure signal acquisition processing unit and the signal display operating device exchange and transmit data through the paired wireless Bluetooth modules; after the pressure test module is connected with an automobile fuel system, the pressure signal is processed into a digital signal, the digital signal is processed by a wireless module into a wireless signal, and the wireless signal is transmitted to the test host computer; after the test host computer receives the test signal, the singlechip compares and analyzes the test signal with the standard data in a memory, judges whether the system pressure exceeds the normal working value, and digitally displays, stores and prints the test result, so that the operator can automatically analyzes the test result without the effects of space and automobile state; and thus, the working mode of the operator is more simple, flexible and intelligent.

Description

technical field

[0001] The invention relates to an automobile fuel pressure test device, in particular to an automobile fuel pressure test device with the functions of printing, storage and analysis while transmitting data wirelessly. Background technique

[0002] The fuel pressure of the automobile fuel system is an important technical index of the fuel supply system in the electronic control system of the automobile engine. It is a basic parameter that must be tested in the process of automobile maintenance. Under normal circumstances, the fuel pressure should be a constant standard value. If it is too large, the fuel injection volume will be increased, the combustion will be incomplete, the fuel consumption will increase, the exhaust will emit black smoke, and the environment will be polluted; if the fuel pressure is too small, the engine power will be insufficient, and the car cannot even be started. At the same time, with the continuous advancement of automotive diagnos...
