State the lower action of signal control of control module 1.The motor drive module 2 is connected with acceleration cable 4, for controlling throttle.Institute
It can be single line or double structure to state acceleration cable 4, can set 2 patterns of auto idle speed and manual idling.The control
Module 3 is connected with function wire harness 5.The function wire harness 5 is opened including throttle motor wire harness, IS Idle Switch line 52 and motor knob
Line 51.The throttle motor wire harness includes main track, negative wire, key line, pressure switch line and proportioning valve line etc..
The motor drive module 2 includes motor, reduction box and bracing wire seat, and the motor is connected by reduction box and bracing wire seat
Connect, the bracing wire seat is connected with acceleration cable 4；Locator is set on the bracing wire seat, for control the operation of acceleration cable away from
From, it is possible to achieve automatically control.The motor drive module 2 is fixed on the inner side of panel 11, and the panel 11 is arranged on the machine
One end of shell 1.
The control module 3 is fixed on the inner surface of bottom 12, and the bottom 12 is arranged on the other end of casing 1.Institute
State and 2 adjustable switchs and 2 charactrons be provided with control module 3, the charactron controllable parameter numerical value between 0-99,
The range size of output current can be changed by adjusting this 2 adjustable switchs and shown on charactron, and feed back to liquid
On the proportioning valve of press pump, the control to hydraulic pump proportioning valve is finally realized.
The utility model is applied on various direct-injection excavators (EFI excavator can not use or need secondary modification),
In use, motor drive module is by DC24V power voltage supplies, locator is by DC 0-5V power voltage supplies, output voltage 0.5-4.5V,
