THE EFFECT OF COOLANT TYPES AND THE ADDITION FANS TO THE RADIATOR WORKING TEMPERATURE OF THE YAMAHA AEROX ENGINE

Abstract

The cooling system functions as a heat absorber generated by the engine during the combustion process inside the cylinder. This research focuses on the effect of coolant type variations and the addition of a fan to the radiator on the operating temperature of the Yamaha Aerox engine. In this context, the researcher will conduct tests using various types of coolant and the addition of a fan to measure the engine's operating temperature. For example, the researcher can describe the characteristics of engine operating temperatures using different coolant types. The lowest radiator temperature was recorded when using coolant with a 50/50 ethylene glycol mixture, reaching 70°C. The results also showed that adding an extra fan to each coolant variation led to a decrease in temperature. The lowest temperature was found with a 40/60 ethylene glycol mixture, at 60.7°C. For the engine block temperature without a fan, the coolest result was with the 50/50 mixture at 57.6°C, and when the fan was operating, it remained the same 50/50 mixture, reaching 53.3°C
