Abstract

The engine performance and durability effects of a barium smoke suppressant additive, Lubrizol 565, and an ashless polymeric additive, Lubrizol 552, in a 25-75 blend (v/v) of alkali refined sunflower oil with diesel fuel were investigated. The study was performed on a direct injected, turbocharged, and intercooled diesel engine. These additives were tested in an attempt to reduce carbon buildup problems observed while using an untreated 25-75 blend of sunflower oil and diesel fuel. Compared to the engine tests on the untreated 25-75 mixture, the barium smoke suppressant additive proved effective in cleaning the inside of injection nozzles (no needle sticking, no carbon build-up inside the orifices), reducing diesel exhaust smoke, and increasing engine power output. However, there was increased residue accumulation in the combustion chamber and on the exterior of the injection nozzle tips. The ashless dispersant additive also improved nozzle cleanliness but did not demonstrate any effect on engine power or cause excessive carbon buildup on the nozzle tips, top of the pistons, and cylinder head. The Lubrizol 552 dispersant looks very promising as an additive for vegetable oil diesel fuel blends for controlling excessive carbon and lacquer deposits.
