Introduction to Advanced Engine Diagnostics

Abstract

In last two decades, advancements in automotive engines and after-treatment technologies have resulted in better engine performance, lower fuel consumption, and lower emissions; however, system complexity and higher number of control parameters have led to optimization issues. Implementation of advanced combustion diagnostic techniques/strategies in internal combustion (IC) engines further reduced the tail-pipe emissions, especially oxides of nitrogen (NO_x) and particulates; however, these combustion strategies have generated a new set of control parameters, which need to be optimized for superior engine performance and emission characteristics. To resolve these complex issues, researchers have combined different techniques such as advanced combustion strategies with after-treatment systems, and experimental research supported by simulations using computational fluid dynamics (CFD) tools . This monograph covers all these topics including advanced fuels and combustion, emission control techniques, after-treatment systems, simulations, and fault diagnostics.
