Description

US Engine Production, Inc have been around a long time—more than a 20 years from now. Manufactured in 1990, these engines continue to be used in ground, marine and boats worldwide. Unlike traditional four-stroke engines. This eliminates the cylinder head and valvetrain—considered among the most complex and costly components in conventional engines and the primary contributors to heat and friction losses. Instead of employing poppet valves for the gas exchange, US Engines are intake and exhaust ports located at either end of the cylinder enabling efficient uniflow air scavenging.
