As the proportion of catalytic cracking oil is raised, the density of blend of oil is increased and an experimental relation is given. Meanwhile, the centane number and calorific power are reduced. Viscosity, however,has a little change. The vaporization characteristic of blend oil is satisfactory for diesel engine. The ignition delay, maximum cylinder pressure and emission of NO and HC are rais- ed. In addition, the fuel consumption is increased because the calorific power of blend oil is less than that of...

As the proportion of catalytic cracking oil is raised, the density of blend of oil is increased and an experimental relation is given. Meanwhile, the centane number and calorific power are reduced. Viscosity, however,has a little change. The vaporization characteristic of blend oil is satisfactory for diesel engine. The ignition delay, maximum cylinder pressure and emission of NO and HC are rais- ed. In addition, the fuel consumption is increased because the calorific power of blend oil is less than that of conventional oil. The above feature may be adapted to diesel engine when the proportion of catalytic cracking oil is less than 40 pe- rsent.
