Chapter 13 - Impact of NOx control measures on engine life

Abstract

The growth in the use of automobiles around the globe shows a highly crooked situation in many aspects, particularly polluting the environment in the form of exhaust emissions. The rigorous regulations governing permissible emissions and energy security concerns have recently triggered research interest in emission-control techniques. Hence, there is a need to focus on environmental pollution, achieve sustainable development of the economics, and develop solutions to meet the mounting demands for clean energy. In this report, a comprehensive review of the impact of nitrogen oxide emissions resulting from automobiles and their control measures on the life of the engine is presented by using conventional as well as alternate fuels. The short-term operation of the engine exhibits better characteristics of the engine in terms of performance and also emissions. But the problem occurs with the long run of the engine resulting in various problems that include lubricating oil degradation, wear of vital engine components, harmful emissions, etc. This report summarizes nitrogen oxide emissions from automobiles and the control measures adopted to control them. In addition, the impact of NOx reduction techniques implemented in automobiles on the life of the engine has been discussed. The results revealed that NOx control techniques adopted in automobiles had a great impact on the life of the engine, including wear of engine components and also degradation of the tribological properties of fuel.
