| Abstract:The low temperature reformed products of PRF50 operation at different reforming temperature and their effects on engine combustion and emission characteristics under medium load were investigated by using a reformer and an engine test bed. Results show that the use of PRF50 fuel releases a small amount of heat in the low temperature reaction at the reforming temperature of 450 K to 750 K, while the temperature inside the reformer remains essentially unchanged. The light hydrocarbon molecules in the reformed products can promote the engine combustion to advance the angle of 50% mass fraction burned(CA50), and the CO and CO2 in the reformed products have an inhibitory effect on combustion. As the reforming temperature increases, the promoting effect of the reformed products increases first and then decreases gradually after reaching the highest value. Moreover, at the same injection timing, as the reforming temperature increases, the indicated thermal efficiency increases first and then begins to decrease after reaching a peak of 2%. |
