AN INTERNAL COMBUSTION ENGINE

摘要

This is an internal combustion engine. The upper part of it contains a working piston (2) which is connected through a conrod (3) to the corresponding journal (4) on a crankshaft (5) placed in the lower part of the body. The said lower part is shaped as a casing (6), whereas the compressor piston (7) is situated within the inner space of the working piston (2). The compressor piston (7) is fixed to the upper part of the body (1) through a hollow stem (8) having an inner transfer port (9) placed below the intake valve (10). The characteristic feature is that the engine is a two-stroke one but operates with pure fuel without any addition of oil, whereupon the lubrication is forced as it is with the well known four-stroke engines. This type of engine enables to be employed as a gasoline or diesel one.
