Effect of thermal barrier coating for the improvement of si engine performanc...eSAT Journals
Abstract As per the second law of thermodynamics the efficiency of the engine depends upon the extraction of work against the heat supplied. Minimisation of heat rejection leads to increase the work. Heat rejection takes place through the engine piston, valves and cylinder heads to the surroundings. The aim of the study is to minimise this heat rejection to the surroundings. Heat transfer through the engine parts is minimised by applying the thermal barrier coating materials on the top surface of the engine piston, cylinder heads and valves. In this study an attempt is made to reduce the intensity of thermal and structural stresses by using a layer of the ceramic material, like Yttria stabilized zirconia (YSZ) which has low thermal conductivity, high thermal resistance, chemical inertness, high resistance to erosion, corrosion and high strength was selected as a coating material for engine component. This study present the effect of coating on the piston and the performance of modified four stroke petrol engine and the emission characteristics of the exhaust gas. Key words: Yttrium – zirconium coating, Low heat rejection, Thermal barrier coatings, Engine performance and Emission characteristics
Analysis and Design Methodology for Thermoelectric Power Generation System fr...Omkar Kamodkar
This paper combines heat transfer and
thermoelectric conversion techniques to create a
thermoelectric generator device for a single-cylinder, fourstroke petrol engine. The system is made up of heat absorbers,
thermoelectric generator, Thermoelectric Generator (TEG)
modules, and an external heat sink. To achieve the goal of
absorbing heat and increasing thermoelectric conversion
efficiently, the heat exchanger surface area and heat-exchange
time could be increased. Thermoelectric generators convert
waste heat into energy directly. This technology will also help
energy conversion systems work better overall. Despite the
fact that TEG production is limited by available technologies,
feasible electricity generation is possible from waste heat
generated by automobiles. The effect of using passive heat
sinks and heat absorbers made of a flat plate with fins of
various cross-sectional areas and materials with forced
convection heat transfer, as well as how current, voltage, and
power are varied, is investigated and presented in tabular
format in the current numerical analysis. By plotting the
results of the analytical and numerical method on relevant
graph, the results of both methods were compared

Effect of thermal barrier coating for the improvement of si engine performanc...eSAT Journals
Abstract As per the second law of thermodynamics the efficiency of the engine depends upon the extraction of work against the heat supplied. Minimisation of heat rejection leads to increase the work. Heat rejection takes place through the engine piston, valves and cylinder heads to the surroundings. The aim of the study is to minimise this heat rejection to the surroundings. Heat transfer through the engine parts is minimised by applying the thermal barrier coating materials on the top surface of the engine piston, cylinder heads and valves. In this study an attempt is made to reduce the intensity of thermal and structural stresses by using a layer of the ceramic material, like Yttria stabilized zirconia (YSZ) which has low thermal conductivity, high thermal resistance, chemical inertness, high resistance to erosion, corrosion and high strength was selected as a coating material for engine component. This study present the effect of coating on the piston and the performance of modified four stroke petrol engine and the emission characteristics of the exhaust gas. Key words: Yttrium – zirconium coating, Low heat rejection, Thermal barrier coatings, Engine performance and Emission characteristics
Analysis and Design Methodology for Thermoelectric Power Generation System fr...Omkar Kamodkar
This paper combines heat transfer and
thermoelectric conversion techniques to create a
thermoelectric generator device for a single-cylinder, fourstroke petrol engine. The system is made up of heat absorbers,
thermoelectric generator, Thermoelectric Generator (TEG)
modules, and an external heat sink. To achieve the goal of
absorbing heat and increasing thermoelectric conversion
efficiently, the heat exchanger surface area and heat-exchange
time could be increased. Thermoelectric generators convert
waste heat into energy directly. This technology will also help
energy conversion systems work better overall. Despite the
fact that TEG production is limited by available technologies,
feasible electricity generation is possible from waste heat
generated by automobiles. The effect of using passive heat
sinks and heat absorbers made of a flat plate with fins of
various cross-sectional areas and materials with forced
convection heat transfer, as well as how current, voltage, and
power are varied, is investigated and presented in tabular
format in the current numerical analysis. By plotting the
results of the analytical and numerical method on relevant
graph, the results of both methods were compared
