IDLE CONTROL

Perfect Power Articles.

 

Idle control is defined as controlling the idle fuel and idle air by monitoring the RPM. This is required if an automatic transmission or an air-conditioner is used.

All Perfect Power Stand Alone Engine Management Systems have idle control.

The idle control (motor, valve!) is a device, which is installed "parallel/bypassing" the butterfly, thus providing an extra air pass when the butterfly is closed.

The idle motor is operated by the fuel injection system in response to the RPM, and the fuel is adjusted in accordance with the manifold pressure airflow.

 


TWO IDLE CONTROL MOTORS ARE ON THE MARKET:

  • 2-wire device: It is a spring loaded to the closed position, and has two connections.
  • 3-wire device: It has three wires, and is electrically driven to any position is sometimes also referred to as a stepper motor.

 

The XMS4 ranges of standalone engine control systems are only compatible with the two wire idle motors.

 

IDLE CONTROL CAN BE DONE BY THE FOLLOWING UNITS:

  • XMS4A Stand Alone range
  • XMS4B Stand Alone range
