the HOME-PG combination caused by the improper air utilization during
combustion. In case of dual fuel mode of operation, incomplete combustion
is mainly due to the higher viscosity of HOME, lower oxidation caused
by the replacement of air by producer gas. This factor could affect the air-
fuel equivalence ratio significantly. In addition, combined effects of lower
energy content of HOME and producer gas, lower adiabatic flame tem-
perature of producer gas, and lower mean effective pressure are respon-
sible for higher HC and CO emission levels. From the Figs. 11.23 and
11.24, it was noticed that combustion of HOME+FO-PG combination
was improved with RCC, and hence, lower HC and CO levels resulted
compared to HCC. Enhanced energy content of blend reduced viscosity
