METHOD AND DEVICE FOR DETERMINING AND ADJUSTING THE UPPER DEAD-CENTRE POSITION IN PISTON ENGINES

摘要

A device for determining and adjusting the upper dead-centre position in piston engines, in which the position of the piston (5) is measured by means of an electrically operated sensor (1). The sensor (1) is an eddy-current sensor. The combustion chamber volume is adjusted by displacing the cylinder part in relation to the crankcase part.
