Reciprocating piston machine for spark ignition engine i.e. four-cylinder engine, has cylinder with wall having signal generator corresponding with signal receivers, where piston rod is provided with annular groove and pressure oil line

摘要

The machine (1) has a piston bolt bearing (7) with an outer thread staying in contact with a piston inner thread (8) of a piston (4) with lower and upper limit stoppers (10, 25). The piston has turbine rings (11, 15) with turbine blades (17, 20), where wall in a cylinder (2) has oil pressure nozzles (12, 18) that are shifted to each other around 180 or 120 degrees. The wall has a signal generator (14) corresponds with signal receivers (13), and a crankshaft and a crank arm have a circular groove. A piston rod (22) is provided with an annular groove and a pressure oil line.
