Özet
İçten yanmalı motorlarda enerji kaynağı olarak genellikle fosil kökenli yakıtlar kullanılmaktadır. Fosil kökenli yakıtların mevcut rezervlerinin azalması ve şehirlerdeki hava kirliliğinin hızla artması, mevcut rezervlerin verimli bir şekilde kullanılması ve/veya çevre dostu yeni alternatif yakıtların geliştirilmesinin önemini artırmaktadır. Alternatif yakıt kullanımı emisyon kontrolünde kullanılan yöntemlerden biridir. Bu çalışmada, çift yakıtla (Ağırlık olarak %30 LPG ve %70 dizel yakıtı) çalışmamn tek silindirli, direkt püskürtmeli bir dizel motorunda egzoz emisyonlarına etkileri araştırılmıştır. Deneyler sırasında motor hızı (1650 d/d) sabit tutulmuştur. Deney sonuçları çift yakıtlı çalışmada NO_x ve duman emisyonlarının azaldığını göstermiştir.
Generally fossil based fuels are used in internal combustion engines as an energy source. Excessive use of fossil based fuels diminishes present reserves and increases the air pollution in urban areas. This enhances the importance of the effective use of present reserves and/or to develop new alternative fuels, which are environment friendly. Use of alternative fuel is a way of emission control. In this study, reduction of exhaust emissions from diesel engines were investigated. For this purpose a single cylinder, direct injection diesel engine was modified to operate with dual fuel operation (30% LPG and 70% diesel fuel by weight). During the experiments engine speed was kept constant (1650 rpm) and load was changed. It was obtained that; NO_x and smoke emissions were reduced with dual fuel operation in the experiments.
