Study for the Effects of Fuels and Engine Load & Speed on Formation & Emitting of Diesel Nano-Particles

Abstract

It is mandatory to research of diesel engine for not only improvement of fuel consumption（Low CO₂）to realize the low carbon society but also reduction of exhaust emissions and nanoparticles to keep the air quality and human health. In this research, the number of nanoparticles and particle size distribution of diesel engine were measured by changing of the engine loads and the engine speeds in detail, when the test fuels were JIS2D and bio-diesel fuel (BDF) made by waste cooking oil. And the ratios of Elemental Carbon and Organic Carbon in nanoparticles were analyzed and also the particles were observed and the single particle size was measured by Transmission Micro Scope. Then this paper introduces those results and reveals the phenomenon for the formation and emitting of nanoparticle of diesel engine.
