Abstract:
This paper presents an experimental study for estimate the waste heat energy from the exhaust gases of a 1 ton pickup, from the statistics of department of transportation showed that the proportion of using the pickup is 301,942 units in 2012. Experimental study of waste heat was tested via dynamometer at the speed from 700 to 3,000 cycles/minute. At the same time, measured value of Engine speed, Exhaust pipe temperature, Exhaust temperature, Air temperature into intake manifold, Fuel consumption, Air flow rate into intake manifold and the exhaust gases component. After that the data from the measurements were used to calculate the equations to estimate waste heat energy from the exhaust gases. From the result found that the waste heat from the exhaust gases is increasing when velocity is increased compared with the thermal energy of the fuel input. As the result, waste heat energy ratio is up to 84.52 percent.
