Reduction of NOx emission on NiCrAl-Titanium Oxide coated direct injection diesel engine fuelled with radish (Raphanus sativus) biodiesel

Abstract

The main aim of this study is the experimental investigation of single cylinder DI diesel engine with and without coating. Diesel and radish (Raphanus sativus) oil Methyl Ester are used as fuels and the results are compared to find the effect of biodiesel in a thermal barrier coating engine. For this purpose, engine cylinder head, valves, and piston crown are coated with 100 lm of nickel-chromealuminium bond coat and 450 lm of TiO 2 by the plasma spray method. Radish oil methyl ester is produced by the transesterification process method. From the experimental investigation, slight increase in specific fuel consumption in thermal barrier coating engine is observed when compared with the uncoated engine, whereas NO x , HC, Smoke, and CO emissions decreased with coated engine for all test fuels used in the coated engine when compared with that of the uncoated engine.

Energy recovery of waste plastics into diesel fuel with ethanol and ethoxy ethyl acetate additives on circular economy strategy

“…Additionally, the oxygen in the fuel aids in fuel combustion, reducing smoke output. Ravikumar and Senthilkumar 39 found an 8.6% to 21.28% reduction in smoke in the coated engine than a standard diesel engine. Compared to diesel, waste plastic fuel produced an 18.8% to 39% greater amount of smoke.…”

Titanium Dioxide as a Catalyst in Biodiesel Production

“…Optimized conditions in continuous flow, resulted improved by modifying parameters such as temperature, pressure, and residence time and also allowed a possible recovery and reuse of [59], with the permission of AIP Publishing).…”

“…The application of TiO 2 coating slightly increased Specific Fuel Consumption (SFC), emissions of CO, smoke density, HC and NOx and decreased brake thermal efficiency. From the above experimental results, it was demonstrated that B25 with TiO 2 -coated mode of engine operation gave better performance and lower emission characteristics including NOx, without requiring any major modification of engine [59]. Consumption (SFC), emissions of CO, smoke density, HC and NOx and decreased brake thermal efficiency.…”

Nd katkılı Seramik Malzeme ile Kaplanan Bir Dizel Motorda Yanma Karakteristiğinin Araştırılması

“…Düşük ısı kayıplı motor uygulaması ile motor testlerinde, özgül yakıt tüketiminde % 4-7,1 oranında azalma, egzoz gazı sıcaklıklarında % 3,5-6,8 artış ve hacimsel verimde % 0,9-2,6 artığı tespit edilmiştir. Ayrıca motor performansındaki bu pozitif etkilerin deney motorunun izolasyonu ile ilgili olduğu tespit edilmiştir[13] [16]…”
