Abstract
In order to realize stable oil consumption to the engine mode of operation in a market, the mechanism in a broad operating range needs to be grasped. Various evaluations of the piston ring motion, piston land pressure, and visualization in the operation range of a slowdown, a low speed, and high-speed fixed load were carried out. About visualization evaluation, it carried out drawing oil film distribution from image analysis. Examination and prediction of the oil action were performed for how it results in oil consumption generating.
