| Summary: | 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. |
