Alcohol is considered one of the effective alternative fuels, with the intention of reducing air pollution and ensuring a stable energy supply. It is known that valve surfaces in fuel injectors are worn for methanol fueled engines. It is important to make the wear mechanism clear in methanol for the practical use of methanol fuel vehicles. In this study, a steel bearing ball was collided repeatedly with a fiat hard plate in three kinds of alcohol which are methanol, ethanol, propanol and three kinds of paraffin hydrocarbon which are pentane, hexane, heptane. Electric resistance between the ball and the plate, which is corresponded to metallic contact rate, and collision load were measured. Undergoing the impact, squeeze film was formed, and whose characteristic was investigated by examining the relation between the metallic contact rate and the mean contact pressure. It revealed the impact load carrying capacities of alcohol and paraffin hydrocarbon.
