Abstract
This study describes the engine combustion characteristics of the gasoline surrogate fuels for Japanese market fuel, which has been studied by Gasoline Combustion Team in Cross-ministerial Strategic Innovation Promotion Program (SIP) Innovative Combustion Technology. Lean combustion characteristics and anti-knocking quality of those surrogate fuels which are consisted of 3 and 5 components show good agreement with regular and premium gasoline in Japanese market. The analysis with detailed reaction mechanism developed in the gasoline team on knocking has been conducted. The results are also introduced.
