Paper 2: The Nature and Cause of Diesel Emissions

Abstract

The purpose of this paper is to review, necessarily rather superficially, the broad question of emissions from diesel engines and their relation to combustion as seen from an engineer's point of view.

From the previous paper it will be realized that smoke is the emission currently under strongest scrutiny. Nevertheless, as gasoline engine emissions are brought under more rigorous control there also will be pressure to control unburnts, oxides of nitrogen, and other emissions from diesel engines.
