Development of a new method to measure the rotational force acting on the piston rings of a gasoline engine 2019-01-2366

Oil consumption of an engine causes particulate matter, poisoning catalysts and sometimes abnormal combustion like pre-ignition. One of the factors of oil consumption is oil transport via a piston ring-gap. Coincident of ring-gaps at a same position may cause an increase in oil consumption. It was assumed that the rotation of a ring in the circumferential direction is affected by cylinder bore shape, piston motion, distribution of ring tension and so on. The force which caused ring rotation was measured by a newly developed cantilever type of load cell which is set in the ring gap. The force was assumed to be closely related to the piston motion.
