In this study, the effects of oxygen enriched
intake air on engine performance and exhaust emissions were investigated
experimentally. All experiments were carried out in a warm-up period of a LPG
spark-ignition engine by delivering the oxygen to the intake air at different
mass ratios. The oxygen enriched intake air improves combustion efficiency
which has positive effects on engine performance, HC and CO emissions but on
the other side it has been observed that NOx emissions are adversely affected
by oxygen enrichment.

LPG YAKITLI BUJİ ATEŞLEMELİ MOTORUN ISINMA PERİYODUNDA OKSİJEN İLE ZENGİNLEŞTİRİLMİŞ EMME HAVASININ PERFORMANS VE EGZOZ EMİSYONLARINA OLAN ETKİLERİNİN İNCELENMESİ

Öz

Bu çalışmada, oksijence zenginleştirilmiş emme
havasının motor performansı ve egzoz emisyonlarına olan etkileri deneysel
olarak incelenmiştir. Tüm deneyler; LPG’li buji ateşlemeli motorun ısınma
periyodunda kütlesel olarak farklı oranlarda oksijenin emme havasına sevk
edilmesi suretiyle gerçekleştirilmiştir. Emme havasının oksijence
zenginleştirilmesinin yanma verimini iyileştirerek motor performansı,  HC ve CO emisyonları üzerinde olumlu etkilere
neden olduğu tespit edilirken NOx emisyonlarının olumsuz etkilendiği
gözlemlenmiştir.
