Step motor-based electronic fuel injection car nozzle cleaning machine

Abstract

The invention discloses a step motor-based electronic fuel injection car nozzle cleaning machine which comprises a power circuit module (1), a control module (2), a timing alarm module (3), an external storage module (4), a human-machine interface module (5) and a software execution mechanism (6), wherein the power circuit module (1) is connected with each of the control module (2), the timing alarm module (3) and the software execution mechanism (6). By connecting connectors with an oil supply pipe and an oil return pipe of the engine, the cleaning machine can be used for cleaning the electronic fuel injection car nozzle under the condition that the engine goes right. The step motor-based electronic fuel injection car nozzle cleaning machine is divided into five modules: the power circuit module, the control module, the timing alarm module, the external storage module and the human-machine interface module. According to the step motor-based electronic fuel injection car nozzle cleaning machine, a single-chip microcomputer is adopted to control a step motor; in the single-chip microcomputer-controlled step motor system, the step motor is driven through controlling the CP pulse waveform output by the single-chip microcomputer; the method is simple and less in occupied resource; the control method can be realized by software; and through calling the clock subprograms of different periods, the control of the rotating speed of the step motor can be realized.

Description

Technical field [0001] The invention relates to a nozzle cleaning machine, in particular to an electronic injection automobile nozzle cleaning machine based on a stepping motor. Background technique [0002] The fuel injector is an important component that affects the EFI car engine, and its performance status will directly determine whether the EFI engine can work normally. But nowadays, many car owners don't pay much attention to the cleaning of engine injectors. Most people think that the cleaning of engine injectors does not need to be too frequent. They don't know that if the injectors are blocked, it will greatly affect the performance of the engine. These deposits will seriously affect the fuel system of the car. The deposits will block the fuel injection nozzle, affect the normal operation of the fuel injection nozzle, and then affect the operation of the car engine, and ultimately affect the driving performance of the car. Sediment will form solid matter at the nozzle i...

But now many car owners do not pay much attention to the cleaning of the engine fuel injectors. Most people think that the cleaning of the engine fuel injectors does not need to be too frequent, but they do not know that if the fuel injectors are blocked, the performance of the engine will be greatly affected.

These deposits will seriously affect the fuel system of the car. The deposits will block the fuel injector, affect the normal operation of the fuel injector, and then affect the operation of the car engine, and finally affect the driving performance of the car

Deposits will form solid matter at the inlet nozzle, which will directly cause the needle valve of the fuel injector to be closed tightly, which will cause unstable speed of the engine during acceleration, increased fuel consumption, and deterioration of exhaust emissions; at the same time, deposits will be on the inner wall of the cylinder A hard shell is formed on the top of the cylinder. This shell has high capacity and poor thermal conductivity, which will affect the thermal conductivity of the inner wall. When the engine is running, the internal temperature of the cylinder will rise sharply, and in severe cases, it will cause major accidents such as cylinder explosion or engine shock; From this we can say that the work of the fuel injector will directly determine whether the EFI engine can work normally.
