AN INTERNAL COMBUSTION ENGINE, TWO STROKE AND WITH ALTERNATIVE PISTON.

摘要

The invention relates to a two-stroke reciprocating piston internal combustion engine with inlet port and outlet port controlled by the piston, in which in the cylinder wall a connecting duct, similarly controlled by the piston and of relatively small cross-section is provided, which is provided in the form of an inclined bore or groove running parallel to the cylinder axis in order to connect the bottom area of the compression chamber in the cylinder to the overflow duct or also to the outlet duct, by means of which a very low-speed starting process to be undertaken manually by means of a cable is made essentially easier, whilst only a negligible loss of output occurs in the operating speed of the engine.
