Research of Fuel Components to Expand lean-limit in Super lean burn condition (part III)

In this research, we investigated the improvement of combustion and anti-knocking properties as factors that affect the lean limit in order to reflect in fuel design. First, as a basic study, characteristics such as the Laminar burning velocity and Ignition energy of hydrocarbons, which are highly effective in improving combustion speed, were examined. In addition, using the knowledge obtained in the basic study, several concept fuels were created by blending the blend- stocks of the refinery aiming to meet or exceed the current standards in Japan. Their lean limits, thermal efficiencies, and effects on CO2 emission were investigated.
