N2 - One of the properties of bioethanol fuel that causes a difficult initial startup is the evaporative heat of bioethanol, which is three times greater than gasoline fuel, which is 904 kJ/kg [1], requiring greater energy for ignition. One solving strategy is to provide preheat treatment to the fuel so as to reduce the energy requirement for the initial ignition. This study wants to know the effect of the amount of preheating to the initial process of ignition. This study was conducted on a dedicated bioethanol SINJAI-150 engine with a port injection fuel injection system with variations in fuel temperature before entering the injector. The heating mechanism conducted is by heating the fuel in a mini chamber with a power of 50 Watts using an electromagnetic induction heater. The fuel temperature before entering the injector is varied by 60, 70, and 80°C using a thermo-switch control system. The initial startup level is measured by the number of kick start periods required to start the engine and the heating time. The results showed that the 50 Watts heating system was able to heat the fuel to 80°C in 16.5 seconds and required a kick start period to start the engine during cold-ignition conditions. From the performance measurement indicated that the best performance resulted on heating of bioethanol fuel 70°C, that is with the increase of 6,23% and emission in HC and CO decreased 71,85 ppm and 1,48%. For the AFR value tends to rise along with the increase of fuel heating process.
