OPERATION

There are two channels in each intake manifold for each cylinder. A charge air intake passage (3) and a swirl intake passage (2). The swirl passage (2) incorporates a blade (2) that is continually adjusted through linkage (4) and an actuator (5) when ever the engine is running. The actuator (5) is controlled by the ECM through a PWM signal. As engine speed and load increase the swirl channels adjust for optimized air turbulence and air mass requirements. When the engine is not running, the swirl channel blades (2) are held open by and integrated spring .
