Abstract
Gas turbine engine using turbocharger (also known as micro gas turbine engine)
is a small-scale gas turbine engine that can be used to drive a portable power generator
and has a potential to produce low emission. In this project, a small gas turbine engine
is developed using a turbocharger from a car engine.
This thesis is focused in designing and fabricating required components and
supporting/auxiliary systems for the operational of the gas turbine engine which are
ignition system, fuel injection system, lubrication system, air ducting and combustion
chamber. In this report, the designing and fabricating method for all auxiliary systems
and combustion chamber are presented. The ignition system used conventional spark
plug system to ignite the fuel-air mixture in the combustion chamber. The fuel used is
butane gas which is a type of fuel that used in cooking purpose. Lubrication system is
required since the rotating shaft inside the turbocharger which is directly connected
with compressor wheel and turbine wheel will rotate at several thousand revolutions
per minute during the operation. A simple lubrication system is designed and fabricated
to deliver an amount of lubricating oil on the rotating shaft to reduce wear and for
longer lifespan.The combustion chamber is the most crucial part. It consists of two main parts
which are flame housing and flame tube. These parts are carefully designed to get the
perfect combustion for the engine to self-sustaining the combustion process. In this
report, the method in designing the combustion chamber also presented. The designed
combustion chamber is studied to determine whether it is suitable for this project or
not. After all systems and combustion chamber are completely fabricated, the system is
assembled with the turbocharger and the engine is tested for several times. The
operational performance of all system and the gas turbine engine also are observed
during the engine operation. All problems encountered in each system and its solutions
are presented.
