ABSTRACT
This study shows the simulation of thermostatic valve in the cooling system of Spark Ignition (SI) Engine and the behavior of warm up period for difference ambient temperature. There is a condition in the field if there is malfunction on thermostat the fastest solutions to do is to remove it. This study result shows that the simulation without thermostat have 3 time longer than a system with thermostat to reach the working temperature. If the time to reach the optimal temperature last longer, the combustion process becomes inefficient. The experimental data will be used to calculate new equation for difference ambient temperature and the result shows the recommendation to fix the cooling system with new thermostat rather than remove it.
