Title:
TWO-STROKE ENGINE HAVING INDEPENDENT COMBUSTION CHAMBER AND SPECIAL PISTON AND WITH SYNCHRONOUS BOOSTING
Document Type and Number:
WIPO Patent Application WO/2020/164395
Kind Code:
A1
Abstract:
Disclosed is a two-stroke engine having an independent combustion chamber and a special piston and with synchronous boosting. A high-pressure gas synchronously compressed by a larger end face of a special piston passes through a compressed gas channel (8) and is stored in an independent combustion chamber (10), fuel combusts in the independent combustion chamber (10), and a high-temperature high-pressure gas expanded after combustion does work on a smaller end face of the special piston, thereby solving problems, such as fuel requirements being too high, engine knock and the non-adjustable compression ratio of the existing engine, mixing combustion of engine oil and fuel oil of a two-stroke engine, serious emission pollution, and a low working efficiency defect of a four-stroke engine. Under the same existing conditions, the power of an engine approximately doubles (or about half of fuel is economized), and the engine has a thermal efficiency of about 50%, thereby realizing full combustion and saving on energy.
