The Assisted air control valve has the task of supplying the air surrounded injectors with air. This results in better volumetric efficiency, more effective combustion and therefore cleaner exhaust emissions. The valve is also used for idle air trim but is also slightly open at higher engine speeds and is then held in standby mode.
