The Effect of a homogeneous combustion catalyst on diesel consumption in south african engines

Fuel performance catalyst (FPC) is the homogeneous combustion catalysts supplied and distributedby GreenThermo Energy Pty Ltd (GTE) in South Africa. The FPC is a ferrous picrate water butanolsolution with additives. These additives are mainly short chained alkali benzenes used to stabilize thecatalyst mixture. The influence of fuel performance catalyst in diesel engines is investigated to createseamless Green fleet solutions by reducing fuel consumption within business environments. Fueleconomy in internal- combustion engines aim to convert chemical energy is to the maximum amount ofuseful work. This paper presents experimental results that provide the optimum fuel performancecatalyst (FPC) dose in Nissan UD60 diesel direct ignition trucks, rolled out at Premium Packaging PtyLtd. The fuel consumption was measured as a function of catalyst dosing ratio and distance travelled.The FPC was able to reduce fuel consumption through the field testing method and it was concluded.The FPC integration strategy recommended suggested that an opportunity exists for PremierPackaging, if the trucks were representative of the median population in their truck fleet, an averagegeneral fuel consumption of 24L/100Km within 12 months could be achieved. The results werecompared to baseline performance of 27L/100Km prevalent at the beginning of FPC dosingimplementation, which is within 95% prediction interval. An improvement of up to 3L/100Kmrepr esents 11% reduction in fuel cost impact year - on-year.
