Effects of Fuel Components on Thermal Efficiency in Super Lean Burn S.I. Engine

Abstract

Toward the realization of carbon neutrality, it is expected to improve engine thermal efficiency by combining combustion and fuel, as well as reduce WTW CO₂ by reducing the carbon intensity of fuel. In this study, the evaluation of the effect of fuel molecules on thermal efficiency and exhaust emissions using a highly efficient super lean burn engine of λ2 or higher is conducted, and the characteristics required for fuel is clarified.
