Seven combustible mixtures of condensate / diesel were evaluated with the aim to delimit the extent at which the adulteration of automotive gas oil (AGO) with condensate samples from two different sources becomes harzardous to Diesel engines. Results of the quality assurance test (low CN (cetane number), low boiling point (IBP (initial boiling point), FBP (final boiling point), TR (total recovery)) ranges of atmospheric distillation, high cloud point) show that 4 100 % (v/v) of condensate in the adulterated blends are undesirable for diesel engines. Blending condensates in diesel, results in black diesel smoke from inadequate air / fuel mixing in the cylinder with locally over-rich zones, higher fuel injection rates, dirty injectors and injection nozzle tip wear resulting from over use can lead to locally over-rich zones in the combustion chamber.
