Application of carbon nanotubes as additives improving the environmental performance of diesel engine

Abstract

The actuality of the article is due to the need to improve the toxicity indicators of dieselengines exhaust gases. One of the modern ways to achieve the required indicators of exhaustgas toxicity is to add eco-friendly additives to the fuel. An opportunity of using carbonnanotubes as eco-friendly additives to petroleum diesel fuel is considered. Experimentalstudies of the D-243 diesel engine running on petroleum diesel fuel with the addition of 125,250 and 500 mg/l nanotubes were carried out. Mixing of petroleum diesel fuel with nanotubeswas performed with the usage of an ultrasonic apparatus. A possibility of improving theenvironmental performance of a diesel engine when adding nanotubes to the fuel is shown. Ina full-load mode, the addition of 500 mg/l carbon nanotubes to the fuel reduced the exhaustsmoke from 26.0 % to 11.2 % according to the Hartridge scale.
