Diesel and DieselLTCCombustion

Abstract

Conventional and low temperature diesel combustion systems are reviewed from a broad perspective, beginning with a summary of practical design considerations. This material will provide practicing engineers a comprehensive review, and for those new to the field, an overview of what is essential and references for further information. The practical considerations are followed by a description of the fundamental physical processes controlling the combustion process. With this background, an overview of the evolution of the combustion process is provided and the impact of various design parameters on this evolution is discussed. Our objective is to provide the combustion system designer a strong physical understanding to guide his development of modern, low emission, high efficiency diesel combustion systems.

A review of design considerations for light-duty diesel combustion systems

“…This article is a highly condensed version of a more complete work, to which we refer the reader interested in linking these more practical aspects of combustion system design to the fundamental physics governing the combustion process. 72…”

Materials Design for the Improvement of SiC Field Effect Gas Sensor performance in High Temperature Process Control applications

“…Still, technological improvements such as reduced heat transfer and frictional losses as well as optimized turbocharging and fuel injection systems have demonstrated the possibility to increase fuel efficiency by up to 10% [91]. For a more elaborate treatment on the impact of engine design and operation on the efficiency of diesel engines as well as on future potential options to improve from best-in-class 45% thermal efficiency today to over 50% see [92] and [93].…”

Effects of a CFD-improved dimple stepped-lip piston on thermal efficiency and emissions in a medium-duty diesel engine

“…9 SL pistons also have smaller surface area-to-volume ratio than re-entrant bowls, therefore, the heat losses through the piston surfaces are also reduced. 10 On the other hand, wall heat loss was determined to not be as effective as the degree of constant volume combustion at improving thermal efficiency. 8 Such SL pistons are readily available in modern production diesel engines.…”
