ABSTRACT:
A multiple stage supercharging system is disclosed suitable for both two-stroke cycle and four-stroke cycle internal combustion engines. Ambient air, which is propelled by the forward velocity of the engine, enters an air cleaner housing (11) through an air filter. The air cleaner housing (11) attaches to the air intake (32) of a centrifugal compressor (12). The centrifugal compressor (12) mounts directly to the magnetic flywheel on the crankshaft of the engine. The centrifugal compressor wheel (22) pressurizes the ambient air for use in the combustion process. The outlet of the centrifugal compressor housing mates with a secondary plenum chamber (17). The outlet of the secondary plenum chamber (17) mates with a d.c. motor driven axial compressor (28). The axial compressor (28) operates on current derived from a motor driven alternator (38). The outlet of the axial compressor connects to a primary plenum chamber (18) which connects to the air intake snorkel on the carburetor. A pressure equalization tube (19) extends from the primary plenum chamber to the carburetor bowl to allow for consistent flow of the air/fuel mixture to the crankcase. The system provides for multiple compressors to generate layers of additive pressure for supercharging an internal combustion engine. The system provides air pressure to boost the power output of the engine across the entire rpm band by utilizing the centrifugal compressor (12) and the axial compressor (28) at low speeds and by utilizing forward air velocity air intake pressure plus the centrifugal and axial compressors at high speeds.
