The effect of changing in ambient temperature plays an important role to the performance of machine and equipment. Therefore increasing of surrounding temperature in the world nowadays will effect the performance and the quality of air especially related to internal combustion engine. Internal combustion engine also known as heat engine depends so much to the changes in temperature. This thesis present the simulation study and experimental result on the performance of internal combustion engine at different ambient temperatures on small four-stroke spark ignition engine. It also investigated the level of emission released to the environment due to increase in ambient temperature. A small four stroke spark ignition engine attached to dynamometer has been used in this study. This thesis constructed to provide the data of engine performance parameters such as brake power, specific fuel consumption, brake mean effective pressure etc and exhaust emission by using GTPower simulation data and supported by result from an experimental work. While, the exhaust emissions are of CO2, HC and O2 that were measured by using gas analyzer. The data were taken at four different ambient temperatures 30 °, 35 °, 40 ° and 45 °C. Increasing in the ambient temperature resulting to small improvement in the engine performance. The higher the ambient temperature, the lower emission were produced.
