An Experimental Study on Effect of Piston Friction and Lubricating Oil Consumption on Lower Tension Piston Rings

Event: JSAE Spring Conference
This study was aimed at clarifying the effect of lower tension piston rings on piston friction and lubricating oil consumption (LOC). Floating liner method and sulfur tracer method were applied simultaneously to measure the piston friction and LOC with gasoline engine. This paper described the ratio that each ring tension acts on both piston friction and LOC. In order to verify the reasons, oil film behavior around the piston and rings were observed by the engine with optical glass window.
