Abstract

The objective of this report is to compile and report all information, findings, data and other gains from the research of this topic which is the study on operating engine temperature in relation with engine performance. One of the important systems in engine vehicle is cooling system. Cooling system is designed to provide optimum temperature in order to reach operating temperature quickly and also maintain that particular temperature. Cooling system is also responsible to remove excess engine heat. This research is conducted to study relationship between engine temperature and engine performance. In order to study that particular relationship, experiment must be conducted to know the standard condition of the vehicle operating temperature which is the moment the vehicle has already warm up and radiator fan already function. Then this vehicle will undergo the chassis dynamometer test to know the relation between the temperature and performance through a few series of dynamometer test run. After the standard condition has already known, DC motor speed controller is developed whereby it will be used in the next chassis dynamometer test to observe the relationship of the input which is voltage and the output temperature. The input voltage is related to the radiator fan. Therefore, from this experiment, we can notice the relationship of variable fan speed of radiator fan to the temperature of the engine using this DC motor speed controller as a medium to give variable input voltage. Finally, a concept study of Fuzzy Logic controller is conducted in order to develop the simulation model using this type of controller and also the automatic variable fan speed cooling system in future.
