| description | This paper experimentally investigates the thermal balance and performance of a turbocharged gas spark
ignition engine. The First Law of Thermodynamics was used for control volume around the engine to
compute the output power, transferred energy to the cooling fluid, exhaust gases and also unaccounted
losses through convection and radiation heat transfer. Thermal balance tests were performed for various
operational conditions including full and half loads and different cooling fluid temperatures. Results
indicate that by increasing engine load and coolant temperature, the percentage of transferred energy to
the exhaust gases increased while the percentage of coolant energy decreased. Also, experimental data
reveals that using gaseous fuel and a turbocharger (TC) in the engine leads to 4.5% and 4% more thermal efficiency than gasoline and natural aspirated (NA), respectively. Also, second law analysis reveals that using a turbocharger leads to a 3.6% increase in exergetic efficiency of the engine, averagely. Based on experimental results, an empirical correlation was suggested for computing the energy of exhaust gases which shows good agreement with the experimental data for the majority of operating conditions. |
