Abstract

DC60 (03/07/44) This is a two-stroke engine with a separate intake chamber, a lubricant-free two-stroke design. It utilizes volume changes in the crankcase, air compression, and intake chambers to primarily charge the fuel-air mixture (or intake air). A diaphragm or wind deflector prevents the mixture from flowing into the crankcase and also prevents lubricating oil from flowing into the combustion chamber. A pressure control valve helps balance the pressure in the air compression and crankcase chambers, resulting in efficient intake charging. Furthermore, it eliminates the need for two-stroke lubricating oil or autolube, leading to more complete combustion and effectively reducing white smoke in the exhaust gases. This two-stroke engine with a separate intake chamber, a lubricant-free two-stroke design, uses volume changes in the crankcase, air compression, and intake chambers as its main function in charging the fuel-air mixture (or intake air) via a diaphragm or wind deflector to prevent the mixture from flowing into the crankcase. To prevent lubricating oil from flowing into the crankshaft chamber and into the combustion chamber, a pressure control valve is used to regulate the pressure in the air compression chamber and crankshaft chamber. This balances the pressure, resulting in efficient intake and eliminates the need for two-stroke lubrication or autolube. Consequently, it leads to more complete combustion and effectively reduces white smoke in the exhaust gases.
