윤영춘(Young-Chun Youn),권기린(Ki-Rin Kwon) 한국자동차공학회 1997 한국자동차공학회 춘 추계 학술대회 논문집 Vol.1997 No.6_1
The purpose of this study is to prevent the stick, scuffing, scratch between piston and cylinder in advance, to obtain data for duration test in actual engine operation. Therefore, temperature gradient in peripheral and axial distribution of cylinder bore were measured in use of 800cc class gasoline engine. The results obtained are summarized as follows ;<br/> 1) The maximum reaction force by overlap is 101.97kg. The skirt length at that position is 10mm from skirt upper.<br/> 2) The rear side temperature of top dead center is 142℃ in peripheral distribution, it is about 20℃higher than thrust, anti-thrust, front side temperature.<br/> 3) The rear side temperature of bottom dead center is 125℃ in axial distribution, whereas the rear side of midway position temperature is 120℃.<br/> 4) The temperature of cylinder wall is about 20-30℃ higher than temperature of cooling water.<br/> 5) The temperature of cylinder wall at top dead center in use of SAE 30^* lubricating oil is 16℃ higher than SAE 20^# at 6000rpm.<br/>

윤영춘(Young-Chun Youn) 산업기술교육훈련학회 2010 산업기술연구논문지 (JITR) Vol.15 No.2
The movement of piston ring and the amount of blow-by gas were measured and the following results were obtained after the measurement of product linkage between rings and 2nd ring lifting up. 1) The 2nd ring was lifted up near the dead center of compressed top at the range of 2400~3200 rpm from the lower surface of the ring groove and blow-by gas was increased by the twisting of 2nd ring. 2) As the result of measuring blow-by gas, when the 2nd ring was lifted up, the blow-by gas increased too at 2400 rpm. 3) In case of inner bevel, at the point of the 2nd ring lifting up, the amount of blow-by gas increase at 2700~2800 rpm. 4) The 2nd ring stayed on the lower surface of ring groove at near the compressed top dead center till 2400 rpm. After that , the 2nd ring was lifted off from the lower surface at the engine speed of 2600rpm on the low load and 3000rpm on high load. From this result, it seems that the 2nd ring was remarkably improved in the sealing ability.
