The DME control unit calculates the throttle position from the accelerator pedal location and other parameters, and monitors the throttle position in the electric throttle regulator by 2 potentiometers (N45TU2N46TU2: through the magnetoresistive sensor, contactless monitoring). The electric throttle regulator is electrically opened or closed by the DMI control unit.

(1) control the throttle regulator on the electronic valve control system for the following functions

Engine starting (warmer running), used for q45TU2.

Idle speed control. Full load operation. Emergency operation.

(2) the adaptive function of the electric throttle regulator

In order to balance the tolerance of the components, the control of the engine control rigid unit and the throttle need to be adjusted. At this time in a prescribed emergency air point (the interruption of the throttle position) the throttle is completely closed) to study self.

The reset spring is also checked, and the task of the reset spring is to close the throttle in the case of failure.

(3) implementation conditions

In order to adjust the school, the following conditions must be met. The battery voltage is >1V.

The engine speed is <32r/min. The speed of the vehicle is <2km/h. The intake temperature is >-1 C.

The temperature of the engine is >-1 C, <142 C. In addition, the throttle potentiometer is not allowed to fail.

(4) the step of adjustment

When switching to the ignition switch position 2 each time, check the throttle setting in the case of electricity. The throttle must be in an emergency air point at this time. At the emergency air point throttle, because a single spring force still opens a gap, so that when the throttle door is closed, it can still get enough air for the engine's emergency trip. If the measured point of emergency air outside allowed range, will be home a fault memory.

Open the door and then closed solar term, can check whether the location of the reset spring to return to the solar term door Penghu emergency air point. There is also a self-contained fault code here. To avoid the throttle of the throttle in the operation of the lower part of the mechanical limit, but also to learn about this. If the measured lower mechanical limit is beyond the allowable range, there will also be a fault word reservoir.

If the adjustment condition is not satisfied, the adjustment has been successfully carried out, and the 4 adjustment will be interrupted in the case of no fault input. The number of adjustments used here last time is applicable.

If the condition of the adjustment is not satisfied, and the adjustment is never carried out successfully, for example, the engine control unit or throttle should be changed, then the adjustment will be interrupted under the condition of malfunction input. The engine is only allowed to perform an emergency operation under all conditions of failure, as the function of the throttle is good.
