The Effect of a Homogeneous Combustion Catalyst on Diesel Consumption in South African Engines / Bir Homojen Yanma Katalizörünün Güney Afrika Motorlarında Dizel Yakıtı Tüketimine Etkisi

Fuel performance catalyst (FPC) is the homogeneous combustion catalysts supplied and distributed by GreenThermo Energy Pty Ltd (GTE) in South Africa. The FPC is a ferrous picrate water butanol solution with additives. These additives are mainly short chained alkali benzenes used to stabilize the catalyst mixture. The influence of fuel performance catalyst in diesel engines is investigated to create seamless ‘Green fleet’ solutions by reducing fuel consumption within business environments. Fuel economy in internal-combustion engines aim to convert chemical energy is to the maximum amount of useful work. This paper presents experimental results that provide the optimum fuel performance catalyst (FPC) dose in Nissan UD60 diesel direct ignition trucks, rolled out at Premium Packaging Pty Ltd. 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 Premier Packaging, if the trucks were representative of the median population in their truck fleet, an average general fuel consumption of 24L/100Km within 12 months could be achieved. The results were compared to baseline performance of 27L/100Km prevalent at the beginning of FPC dosing implementation, which is within 95% prediction interval. An improvement of up to 3L/100Km represents 11% reduction in fuel cost impact year-on-year. Özet: Yakıt performans katalizörü, homojen yanma katalizörü olup Güney Afrika’da GreenThermo Energy Pty şirketi tarafından tedarik edilip dağıtılmıştır. Bu katalizör, katkı maddeleri ile demir pikrat su butanol çözeltisidir. Bu katkı maddeleri başlıca katalizör karışımını sabitlemek için kullanılan kısa zincirli alkali benzenlerdir. Dizel motorlarda yakıt performans katalizörünün etkisi, iş çevresinde yakıt tüketiminin azalması ile çözümlenen kesintisiz ‘Green Fleet’in meydana gelmesi ile araştırılmıştır. Kimyasal enerjiyi dönüştürme amaçlı içten yanmalı motorların yakıt ekonomisi maksimum kullanılalabilir iş içindir. Bu makalenin deney sonuçları, Premium Packaging Pty Ltd şirketi tarafından üretilmiş olan Nissan UD60 direkt enjeksiyonlu dizel motorunda optimum yakıt performans katalizörünün sağlandığını sunmaktadır. Yakıt tüketimi, katalizörün bir fonksiyonu olarak seyahat mesafesi ve oran ile ölçülmüştür. Yakıt performans katalizörü, test metodu alanı boyunca yakıt tüketimini düşürmüş ve sonuçlandırılmıştır. Yakıt performans katalizörü entegrasyon stratejileri, Premier Packaging için filodaki ortalama yoğunluğu temsil eden kamyonlarda 12 ay içinde genel olarak ortalama 24L/100Km yakıt tüketimi elde edildiği fırsatını sunmuştur. Sonuçlar tahmini %95 aralıkta uygulanan yakıt performans katalizörünün başlangıçtaki 27L/100Km performansına göre karşılaştırılmıştır. 3L/100Km’e kadar bir gelişme yakıt maliyeti etkisinin yıl yıl %11 azaldığını göstermiştir.
