REDIV Electronic-controlled Line Pump Measurement Instrument
The measurement instrument can test the RED4 electronic governor inline pump of Japan Jack contest company, it has high reliability, debugging data consistency. The measurement instrument uses a wide lose switching power supply, high speed AMP7 main control chip, integrated circuit, can finish all the RED4 testing functions, high integration, reliable performance and is a ideal debugging instruments in the currently RED4 electronic governor.
1. Introduction:
With the development of electronic technology and people to improve vehicle emissions target, a new type of diesel engine high-pressure pump is going into the market in a growing number, which is electronically control high pressure diesel pump. The difference of this kind pump with the past mechanical high-pressure pump is regulating mechanism and pre-stroke adjusting mechanism. Ordinary mechanical pump uses flyweight and its centrifugal force to realize regulating speed. However, pre-stroke realizes it by adjusting the gasket. Electronically control high-pressure pump achieves speed regulating by using electromagnets or DC motor. Signal size can change amount of fuel injection. Pre-stroke realizes function by increasing control set on plunger or solenoid valve control cavity pressure (VE pump), which is also entirely controlled by signal size. Here, we only introduce electronically control high pressure line pump structure, principles and maintenance.
2. Structure and working principle of RED4 governor
Electron speed regulator on electrically control line pump mainly has 2 kinds: RED3 and RED4. Diesel Machine Co., Ltd of Japan has introduced RED3 electron speed regulator which is used on inline type synthesis pump s early as 1983. Thereafter, they developed RED4 type electron speed regulator.
RED4 type electron speed regulator can be variable speed governor, polarized governor, or a combination of both types. Type of work unit within the conversion process is determined. Therefore, RED4 electronic governor as a general-purpose electronic governor, when applicable, can be applied to trucks, buses, power generation equipment, engineering machinery and fire vehicles and other occasion.
RED4 electronic governor is the main constituent parts: housing, actuators, and cover.
Relative RED3 electronic governor system, RED4 type governor control circuit,
servo circuit, driver circuit, sensing circuit - arranged in the governor's executive body, the outside noise is very small.
Electronic Control Unit is equipped with a RED (RED3 or RED4) series of electronic governor’s line pump system, through computer-controlled direct fuel injection pump diesel engine volume. The system is characterized by: to ensure straight pump diesel engine, low fuel consumption, and can improve diesel engine emissions.
RED4 electronic governor control section can be divided into three parts: the input unit, calculation unit and drive unit.
1) Input unit
The various sensors and switches the output of information into the control unit, the calculation of information processing, information provided to the calculus as the basic unit.
2) Calculation unit
In the calculation unit to input information based on data from the ROM and compare the calculation process and the final result of information as the executing agency of the control information output drive unit.
3) Drive unit
Drive unit to the actuator control information (information about the target gear shift lever) into the actuator driver information, the executing agency action, the gear lever position sensor control, and always make the same target. The conduct of a series of continuous process, so you can always guarantee the best fuel injection engine in the state. RED3 and RED4 comparison of electronic governor
