Where is the idling engine in Pu Sang?

The Pu Sang idle motor is located above the intake manifold.

Idle motor is mainly used to bear the idle speed of the car, and its purpose is to adjust the idle speed according to the engine load when idling. Idle stepper motor is installed on the throttle body and used by the engine controller to control the idle speed of the engine. When the engine speed deviates from the idle speed, it is adjusted by the throttle valve to control the amount of air entering the intake manifold, which is mechanically operated by the accelerator pedal wire rope.

The throttle body has a bypass air passage to provide air when the engine is idling (when the throttle is closed). The pivot of the automatic idle motor extends into the bypass air channel, through which the air flow is adjusted. According to the input signals of various sensors, the engine controller adjusts the engine idle speed by moving the pivot of the automatic idle motor into and out of the bypass air passage.

When the ignition key is turned to the on position, the automatic idle motor starts to work. The switch signal is input to ECU to detect whether the engine is idling. At the same time, the instantaneous position of motor is fed back to ECU through motor position sensor.

Santana fuel-saving skills:

Avoid unnecessary idling. Under normal circumstances, idling a car for more than one minute consumes more fuel than restarting it. Therefore, if the parking time is long, the engine can be turned off.

Try to avoid sudden acceleration and deceleration during driving, and try to keep the speed stable during driving to avoid sudden acceleration and deceleration. Don't slam on the accelerator to accelerate. This will only greatly increase fuel consumption and won't save you much time.

In daily driving, especially when the traffic is not smooth, waiting for a red light and changing lanes, we often see such a phenomenon: there is just a little space in the adjacent lane, and a car here suddenly accelerates to squeeze past, and then has to step on the brakes. Later, the driveway here was free, and I squeezed back as soon as I stepped on the gas pedal.
