Bir dizel motorda dışı plazma sprey yöntemiyle Cr3C2 kaplanmış egzoz borusunun incelenmesi

Öz

Bu çalışmada, içten yanmalı, tek silindirli dizel bir motorun manifold çıkışından susturucuya kadar olan egzoz borusunun dış kısımları plazma sprey yöntemiyle krom karbür (Cr₃C₂) malzeme ile 100 mikron kalınlığında kaplanmıştır. Kaplanmış ve kaplanmamış egzoz borularının emisyon değerleri kayıt altına alınmıştır. Dışı kaplanmış egzoz borusu, standart egzoz borusu ile karşılaştırılmıştır. Dizel motorun egzoz borusunun dış kısmı kaplanmıştır. Egzoz borusunun dış kısmının kaplanmasıyla dışarıya olan ısı transferi azaltılarak zararlı egzoz emisyonları üzerindeki etkileri araştırılmıştır. Deneyler sonucunda; uygulanan kaplamanın egzoz gazlarının soğumasını geciktirmesinin bir sonucu olarak, karbon monoksit (CO), hidrokarbon (HC), karbondioksit (CO₂) emisyonlarının azaldığı, egzoz gaz sıcaklığının (EGS) ve NOx emisyonun ise arttığı tespit edilmiştir.
