Performance and emissions of lemon peel oil biodiesel powered single cylinder direct injection diesel engine loaded with ceria nanoparticles additives and stabilized zirconia coating

The main aim of the present work is to examine the performance and emission characteristics of single cylinder direct ignition diesel engine powered with 3 proportions of lemon peel biodiesel (B10, B20 and B30) using ceria nanoparticles and yttria-ceria-stabilized zirconia as fuel additive and thermal barrier coating (TBC) materials, respectively, using pure diesel as base fuel. From the results of the engine per-formance and exhaust analysis, the volumetric efficiency and friction power increases whereas specific fuel consumption decreases for coated engine and observed insignificant deviation for CO and CO2 emis-sions between coated and uncoated engines. Hence lemon peel biodiesel could be employed in diesel engine with ceria nano particle additive and yttria-ceria-stabilized zirconia TBC.Copyright (C) 2022 Elsevier Ltd. All rights reserved.

Automated summary

The main objective of this study was to investigate the performance and emission characteristics of a diesel engine powered by lemon peel biodiesel and using nanoparticles and thermal barrier coatings (TBC) as fuel additives. The results showed an increase in volumetric efficiency and friction power, as well as a decrease in specific fuel consumption for the coated engine. The CO and CO2 emissions showed insignificant deviation between the coated and uncoated engines.
