Problems solved by technology

However, what this fuel saver controls is the power supply of the engine of the electronic injection vehicle (ECU). Once the ECU is powered off, all the information stored on the ECU will be lost, such as the brake anti-lock braking system (ABS), power steering, and air conditioning system. etc. many electronic systems will not work properly

Embodiment 1

[0011] figure 1 The car engine EFI control fuel economizer shown is composed of three control switches K1, K2 and K3 connected in parallel. K1, K2 and K3 are respectively the normally open control switch linked with the accelerator pedal and the normally open control switch linked with the clutch pedal. The control switch and the control switch linked with the gear position and normally closed only in neutral. The control fuel economizer can be used in series with the electronic injection control circuit of the automobile engine to achieve the purpose of saving fuel.

[0012] When the car is running, step on the clutch pedal, the control switch K2 is closed and conduction, and at the same time put into gear, the control switch K3 is closed, the fuel injector is powered and works normally; The switch K1 is closed and turned on, the clutch pedal is lifted, the control switch K2 is disconnected, the fuel injector can still receive power and work normally; If it is disconnected,...

Embodiment 2

[0015] figure 2 The shown car engine EFI control fuel economizer, its three control switches are relay switches, the main contact of relay J1 is normally open contact, the main contact of relay J2 is normally open contact, the main contact of relay J3 is normally open contact The normally closed contacts, the trigger switches K1', K2' and K3' of the three relay switches are respectively linked with the accelerator pedal of the car, linked with the clutch pedal and linked with the gear position. The control fuel economizer can be used in series with the electronic injection control circuit of the automobile engine to achieve the purpose of saving fuel.

[0016] When the car engine is started, since J3 is in the normally closed state, the fuel injector works normally at this time; The control switch K3' is closed, J3 is disconnected, the fuel injector is powered and works normally; while the clutch pedal is slowly released, the accelerator pedal is pressed, the control switch ...

Abstract

The invention discloses an electronic injection control fuel economizer for an automobile engine. The electronic injection control fuel economizer is composed of three control switches in parallel. The three control switches comprise the normally open control switch body linked with an accelerator pedal of an automobile, the normally open control switch body linked with a clutch pedal and the control switch body linked with gears, wherein the control switch body is normally closed only in the neutral position. The fuel economizer is connected with a fuel spray nozzle power supply of the automobile engine, an electronic control system and a fuel spray nozzle in series, so that the effect of controlling the opportunity of electronic fuel injection for the engine is played during driving of the automobile, and thus the purpose of saving fuel is achieved.

Description

technical field [0001] The invention relates to an electric fuel injection control fuel economizer for an automobile engine, which is mainly a fuel economizer with three control switches connected in parallel to control the timing of the electric fuel injection fuel injection of the engine. Background technique [0002] At present, in the existing automobile engine circuit, a computer-controlled fuel economizer is generally installed, which is used to control the timing of the electric injection fuel injection of the engine, so as to achieve the purpose of saving fuel. This kind of fuel economizer is generally connected in parallel with a micro switch and a temperature control switch. The micro switch is linked with the accelerator pedal, clutch pedal and transmission gear position switch to send out signals. The temperature control switch is installed in the engine cooling system and changes with the operating temperature. Changes, so as to realize the comprehensive control...
