Simultaneous reduction of NOx and smoke emissions with low viscous biofuel in low heat rejection engine using selective catalytic reduction technique

The present work offered a comprehensive investigation on engine characteristics of single cylinder Direct Injection (DI) diesel engine fuelled with Lemon oil (LO) biofuel. LO was obtained from the peels of lemon using steam distillation process. The physio-chemical properties of LO were analysed ba...

TJ Mechanical engineering and machinery The present work offered a comprehensive investigation on engine characteristics of single cylinder Direct Injection (DI) diesel engine fuelled with Lemon oil (LO) biofuel.

Consequently, LO and pyrogallol in PSZ coated engine with post treatment was considered as more advantageous than other fuel samples on account of its performance, combustion and emission characteristics. © 2019 Elsevier Ltd Elsevier 2019 Article PeerReviewed Karthickeyan, V. and Thiyagarajan, S. and Geo, Varuvel Edwin and Ashok, B. and Nanthagopal, K. and Ong, Hwai Chyuan and Vignesh, R.
