Abstract
Diesel engine is preferred over its gasoline counterpart due to high torque output and better fuel efficiency. However, these benefits come at the cost of higher emissions. Engine exhaust particulates from a compression ignition (CI) engine, principally consist of combustion-generated carbonaceous soot. Production of this soot is mainly attributed to incomplete combustion of fuel. A complete understanding of diesel particulate composition is mandatory so that requisite measures can be taken to reduce the engine-out emissions of a CI engine. Information about soot composition helps in chemical and biological characterization of soluble/insoluble organic compounds. This chapter covers the basics of soot emission from CI engines and composition of soot along with its structure. Fundamentals of particle formation, oxidation, adsorption, and condensation of soot have also been discussed in the later part of the chapter.
