THERMAL PERFORMANCE ANALYSIS OF A STIRLING ENGINE ENERGIZED WITH EXHAUST GAS OF A DIESEL ENGINE

Theoretical and experimental investigations indicate that at high loads such as 3/4 throttling or more speeds 3000 rpm more, the exhaust gas temperatures of Internal Combustion engines are about 900-1000 K. The amount heat wasted with is equivalent to power them. By considering this feature engines, a Hybrid engine consisting an (IC) gamma type Stirling was proposed analyzed from thermodynamic point view. formed by combining IC via common crankshaft cylinder. may be four stroke Diesel having unconventional piston crown rod. Via using kind pistons, two chambers created in same cylinder where one them take part above crown, while other taking below crown. In combined presented here, chamber used expansion volume being operational engine. study performance investigated statistical values engines. For engine; 800 K heater surface temperature, 392 cooler W/m2K transfer coefficient regenerator, 300 heater, 250 rad/s speed 12.5 bar air charging pressure were principal inputs. output assumed 120 kW which provides areas cooler, regenerator optimized 0.33 m2, 0.6 m2 4.6 respectively. optimum thermal efficiency determined 47 % 24 kW. total expected increase 6 compared stand-alone average engine, working fluid mass 17g
