ABSTRACT:
One or more cylinders of an engine or machine have the pattern (2) connected to the crankshaft (8) by connecting arm (4) and bearing block (7). Locking and unlocking mechanism (8, 9 and 10) locks the connecting arm and the bearing block when the cylinder is in the active mode; and unlocks them allowing free relative movement between them under conditions of part-load or no-load, to save on mechanical losses even while crankshaft continues to rotate at required machine R.P.M. Locking and unlocking is performed either at the top or the bottom dead center positions of the piston, which is also the parking place for the piston whenever the connecting arm and the bearing block have free relative movement. Auxiliary functions related to the working cylinder are also suspended when the piston is parked.
