Study of the Effect of Gasoline Components on Lubricity

Due to each country’s energy policy, various types of gasoline such as ethanol blended gasoline, high/low aromatic content gasoline, etc. are sold in the market. As the production of engines and their part supply chains become more globalized, it is important to develop engines that can be compatible with various types of gasoline. To maintain engine durability, it is necessary to clarify the effects of these gasoline components on engine durability. To understand the friction of metal to metal contact, which are directly connected to engine durability, we examined synthetically the relationship between gasoline components and lubricity.
