Title: I.c. engine air intake system
Inventor: HALL KEITH GORDON
IPC: F02D9/08
Filed: 1990-03-02
Abstract: Each cylinder has an individual air intake pipe 1-4 and the pipes are connected in cluster formation to a primary air intake duct 8 whose volume is greater than three times that of the individual cylinder volume and provides a flow velocity of less than 20 m/s at maximum engine speed. The construction provides unidirectional flow and minimises inertial fluctuation of the air column and directional changes at the junction. The inertial supercharging may further be enhanced by ensuring that the volume of each air intake pipe is at least 1.25 times that of the individual cylinder volume. The air intake pipes may be arranged in the cluster in engine firing order or, if the engine has an even number of cylinders, with pairs of pipes in anti- phase. The throttle valve 6 is located adjacent the cluster of air intake pipes in the air intake duct and is of the butterfly type so adapted to seal the bore of the air intake duct when fully closed. The periphery of the throttle plate engages ridges or steps (12, 13, Fig. 3) around the bore of the air intake duct when fully closed. The throttle plate closes an opening in a wall (20, 21, Fig. 4) dividing the bore of the air intake duct when in the full throttle position to effect separate streams of air through the throttle body on either side of the throttle spindle. <IMAGE>
