Summary :
|
|
IN THIS ARTICLE A SMALL INTERNAL COMBUSTION ENGINE OPERATING IN OTTO CYCLE IS ANALYZED. A RATIONAL USE OF THE POWER SUPPLIED BY THE FUEL HAS BEEN THE HEAT RECOVERY OF JACKET WATER AND EXHAUST GASES, TO ALLOW FOR THE PRODUCTION OF USEFUL HEAT. THIS PAPER SHOWS THE EXPERIMENTAL STUDY OF AN ENGINE ASSOCIATED WITH TWO HEAT EXCHANGERS FOR THE PRODUCTION OF HOT WATER AT 50OC. BASED ON EXPERIMENTAL DATA THE PRODUCTION POSSIBILITIES OF HOT WATER ARE SIMULATED. THE STUDY CONSIDERS THE TEMPERATURE OF THE EXHAUST GASES, EXIT WATER TEMPERATURE, FLOW OF EXHAUST GASES AND REFRIGERATION WATER AS FUNCTION OF THE ENGINE ROTATIONAL SPEED, RANGING BETWEEN 1,000 TO 2,000 RPM. AS A CONCLUSION A SANKEY DIAGRAM WAS EVALUATED TO INDICATE THE LEVEL OF PERFORMANCE OF THE SYSTEM OPERATING IN COGENERATION VERSION AND THE LEVELS OF RECOVERY CAPACITY OF THE RESIDUAL HEAT FOR HOT WATER PRODUCTION. |
