This paper presents a status report on a preliminary survey of strategies that might be employed to meet US-EPA 1991 heavy duty diesel emission standards without the use of a particulate trap. Although the survey of strategies is not yet complete, that portion dealing with the swirl supported diesel combustion process is sufficiently advanced to allow this status report to be published. It is anticipated that future related reports will provide a view of the complete survey, including quiescent combustion process. This report describes the techniques employed for the steady state approximation of the heavy duty transient test cycle and the analytical procedures used to characterize the particulate composition in terms of insolubles, and the fuel and lube oil related components.read more

Multi-dimensional modeling of thin liquid films and spray-wall interactions resulting from impinging sprays
TL;DR: In this article, a multi-dimensional, fuel film model is proposed to simulate thin fuel film flow on solid surfaces of arbitrary configuration, which is achieved by solving the continuity, momentum, and energy equations for the two-dimensional film that flows over a three-dimensional surface.

Fuel Composition Effects on Heavy-Duty Diesel Particulate Emissions
J. C. Wall,S. K. Hoekman +1 more
TL;DR: In this article, the effects of fuel composition on diesel exhaust particulate emissions have been studied at several steady-state operating conditions using a heavy-duty laboratory engine, and the results showed that fuel sulfur was the dominant fuel factor in particulate formation.
