Equipment for doubling power of four stroke engine, comprises inlet valves which are located at base and side of cylinders and are driven by separate camshafts also exhaust driven fuel compressor

摘要

Each cylinder retains overhead valves (s2) for exhaust and has in addition two admission valve (s1) at the side and base. The spring loaded valves are shaped such that they do not disturb the cylinder shape or lubrication and are driven by separate camshafts (AC1). A first turbine abstracts exhaust gases and uses their energy to drive a second turbine which compresses the fuel supply permanently
