TİTANYUMUN ESASLI YAKIT KATKI MADDESİNİN DİZEL MOTOR PERFORMANS VE EMİSYONLARI ÜZERİNDEKİ ETKİSİ

Yakıt katkı maddeleri, yakıt özelliklerini iyileştirmekte ve yanma verimini arttırmaktadır. Bunun sonucu olarak içten yanmalı motorların performans ve egzoz emisyon değerlerinde önemli iyileşmeler sağlanmaktadır. Bu çalışmada titanyumun içerikli yakıt katkı maddesinin dizel motor performans ve emisyonları üzerindeki etkisi deneysel olarak incelenmiştir. Titanyum (diizopropoksit bis) yakıt katkı maddesi, dizel yakıtıyla (D) 25, 50, 75 ve 100 ppm değerlerinde karıştırılmış ve hazırlanan her bir karışım tek silindirli bir dizel motorda, tam yük şartlarında performans ve emisyon testlerine tabi tutulmuştur. Yapılan testler sonucunda karışım yakıtların tork ve güç değerleri, dizel yakıtı değerleriyle benzerlikler gösterirken, özgül yakıt tüketimi değerlerinde hafif düzeyde düşüşler saptanmıştır. Egzoz emisyon değerlerinde önemli derecede azalmalar gerçekleşmiştir. Özellikle CO ve is emisyonu değerlerinde sırasıyla %64,56 ve %45,19lara varan azalmalar olmuştur.

INFLUENCE OF TITANIUM BASED FUEL ADDITIVE ON DIESEL ENGINE PERFORMANCE AND EMISSIONS

Fuel additives provides an increase on engine performance and a reduction in the amount of the exhaust emissions as a result of improving fuel properties and combustion efficiency of internal combustion engines. In this experimental study, it is investigated the effect of using titanium (diizopropoksit bis) as a fuel additive on diesel engine and emissions. Titanium fuel additive and diesel fuel (D) were mixed with 25, 50, 75, 100 ppm values. In order to determine the performance and exhaust emissions characteristics, a single cylinder diesel engine was fuelled with blended fuels and tested at full load conditions. In conclusion, engine torques and power values of blended fuels were found to have similar values of diesel while specific fuel consumption values decreased. The use of titanium as a fuel additive has led to significant reductions in engine emissions. In particular, CO and soot emissions decreased up to 64.56% and 45.19% respectively.
