Hella Idle Control Valve (6NW 358 192-021)

This Idle Control Valve (6NW 358 192-021) from Hella is the part of the overall idle-speed control of the engine management system that is responsible for regulating the engine speed.

If there is a sudden change to the engine load condition when in idle mode, air and fuel are also required, to prevent the engine from stopping. This could be because of creep speed in 1st gear or air-conditioning (or another electrical consumer unit) being switched on. If the engine speed falls below a certain critical value, an increased air flow rate is achieved by activating the valve.
