Apparatus and method for improving the efficiency of internal combustion engines and fluid pumping devices

摘要

This invention is directed to a novel camshaft for engine timing. The cam positions of the camshaft include secondary lobes in conjunction with normal primary lobes. The second lobes are positioned so that they precede their associated primary lobe during camshaft rotation. The secondary lobes cause an associated valve to open slightly and close completely prior to the normally expected valve opening caused by the primary lobe. This slight opening and closing creates a shock wave that aids the atomizing air and fuel mixing in the intake system prior to normal intake valve opening and enhances the scavenging of combustion gases during the exhaust cycle.
