Abstract

A fuel gasoline engine classified based is octane number, test for octane number using CFR engine with RON (Research Octane Number) ASTM D 2699 and MON (Motor Octane Number) ASTM D 2700. Bioethanol can booster octane number if blended to gasoline. A fuel to a higher octane can be run at a higher compression ratio without causing detonation or knocking engine. Compression is directly related to thermodynamic efficiency but to blended bioethanol can decrease the heating value of the fuel. The design engine on the market had compression ratio specified and needed octane number minimum specified. The experimental using CFR engine and using fuel gasoline in the market with blended bioethanol start from 5% -20% and analysis the relationship octane number after blended bioethanol with value compression ratio gasoline engine at the market. The objective of this research was the effect of blended bioethanol of varying gasoline forward octane number. The effect of blended bioethanol of gasoline between 5%-20% could increase to 11% of gasoline octane 88, 2% of gasoline octane 98.
