Abstract
A two-stroke or four-stroke internal combustion engine operates by admitting a carburated mixture or by admitting fresh air with the direct or indirect injection of fuel. The engine has at least one cylinder, which defines a variable-volume combustion chamber in which an engine piston, coupled by a connecting rod to the wrist pin of a crankshaft, executes a reciprocating movement. A compressor associated with each cylinder to supercharge the cylinder with carbureted mixture or with fresh air has at least one stage and, in the compression chamber, a compressor piston moves and is coupled to the crankshaft by a link rod articulated to an eccentric mounted on the shaft of the crankshaft.
