<p>The inlet manifold for an internal combustion motor, with a single valve at each cylinder with a large valve head, draws in the combustion air without suction from the motor. Air is drawn in from wind flow at the front of the vehicle or a fan/turbine powered mechanically or electrically. The center of the valve drive cam has a flat to retract the valve slightly for the piston to reach a higher top dead center position.</p> |
