INTERNAL COMBUSTION ENGINE AND METHOD OF ENHANCING ENGINE PERFORMANCE

Title:

INTERNAL COMBUSTION ENGINE AND METHOD OF ENHANCING ENGINE PERFORMANCE

Document Type and Number:

WIPO Patent Application WO2004109073

Kind Code:

A3

Abstract:

An apparatus and method to enhance the overall performance of engines in one or more of the following ways: by increasing the power output; by reducing the level of unwanted atmospheric emissions; and by reducing engine wear. The apparatus is an engine (e.g., 2-stroke or 4-stroke, diesel or gasoline-fueled internal combustion engine) comprising a crankshaft, crankcase, combustion chamber, oil pan, piston, connecting rod, intake port, exhaust port, and scavenging pump assembly having an air cylinder and an air diaphragm. The scavenging pump assembly allows for the control of air and fuel intake port pressure by controllably boosting an intake mixture into the combustion chamber, while minimizing the potential for engine lubricating-oil to combine with the intake air-fuel mixture.
