The variation of exhaust gas temperature with brake power for Diesel and producer gas on dual fuel operation is
portrayed in Fig. 4. The exhaust gas temperature of Diesel at full load is found to be 330 C while the exhaust gas
temperature at full load for D+PG4lpm, D+PG6lpm and D+PG8lpm are found to be 365, 378 and 388 C respectively. It can
be observed from the figure that the exhaust gas temperature in dual fuel mode is always higher than Diesel. This is due to
