Energy is widely regarded as one of the key contributors to economic development and personal comfort. Economic expansion and energy use are closely related to one another. The availability of affordable, environmentally acceptable energy sources is necessary for the growth of an economy and for it to remain competitive on a global scale. Conversely, the level of economic development is considered to be affected by energy consumption. Due to rising population and economic development, consumption has recently increased. We are fortunate to have both moderate and renewable energy resources. We lack resources with a high energy density, such as nuclear power plants and fossil fuels. Diesel engines have slowly become more popular over the past century as a fuel-efficient and dependable form of transportation for commodities and the general public, as well as for other essential social needs, including small-scale power generation and other similar activities. They often have advantages over spark-ignition engines due to their reduced regulated emissions of CO, unburned HC & carbon dioxide (CO2) and better thermal efficiency. Diesel engines also have the advantage of using low-energy alternative fuels like biogas since they can run at a higher compression ratio. On the other hand, diesel engines generate dangerous pollutants, including PM and NOx. Because of their potential health hazards and effect on visibility, these emissions are a hazard. When exposed, particulate emissions have the potential to cause occupational cancer and have a number of other negative health effects. Diesel engines, when used as part of a transportation system, are widely acknowledged as a significant source of ambient particulate matter. Natural gas, a widely recognized gaseous alternative fuel, consists of various gas species and is derived from fossil sources. It is possible to find fossil natural gas either by itself or in conjunction with other fossil fuels (eg, coal in coal beds and crude oil in oil fields). Natural gas's properties are fundamentally identical to those of methane (CH4) which is its principal composition.

In today’s global context, there has been extensive research conducted in reducing harmful emissions to conserve and protect our environment. In the automobile and power generation industries, diesel engines are being utilized due to their high level of performance and fuel economy. However, these engines are producing harmful pollutants that contribute to several global threats including greenhouse gases and ozone layer depletion. Professionals have begun developing techniques to improve the performance and reduce emissions of diesel engines, but significant research is lacking in this area. Recent Technologies for Enhancing Performance and Reducing Emissions in Diesel Engines is a pivotal reference source that provides vital research on technical and environmental enhancements to the emission and combustion characteristics of diesel engines. While highlighting topics such as biodiesel emulsions, nanoparticle additives, and mathematical modeling, this publication explores the potential additives that have been incorporated into the performance of diesel engines in order to positively affect the environment. This book is ideally designed for chemical and electrical engineers, developers, researchers, power generation professionals, mechanical practitioners, scholars, ecologists, scientists, graduate students, and academicians seeking current research on modern innovations in fuel processing and environmental pollution control.

This book discusses all aspects of advanced engine technologies, and describes the role of alternative fuels and solution-based modeling studies in meeting the increasingly higher standards of the automotive industry. By promoting research into more efficient and environment-friendly combustion technologies, it helps enable researchers to develop higher-power engines with lower fuel consumption, emissions, and noise levels. Over the course of 12 chapters, it covers research in areas such as homogeneous charge compression ignition (HCCI) combustion and control strategies, the use of alternative fuels and additives in combination with new combustion technology and novel approaches to recover the pumping loss in the spark ignition engine. The book will serve as a valuable resource for academic researchers and professional automotive engineers alike.

The main driving force behind this research was the need for cleaner and more efficient engines to meet the ever-increasing demands on the modern automobile's emissions. In recent years different studies have been carried out to analyze the combined effects of high-pressure injection, boost pressure, multiple injections, included spray angle and combustion chamber geometry. Though considerable research has shown these technologies can meet the low emission regulations, the careful optimization of the engine operating conditions is still required in order to get the full benefit of the different strategies. With these issues as motivation, the first important objective of this study was to gain a detailed understanding of the mechanisms through which fuel injection interacts with other engine parameters and influences diesel combustion and emissions, and hence to attempt to generalize the adoption of multiple injection strategies with regards to improving diesel engine performance. For this purpose, a modified parameter called "Homogeneity Factor of in-cylinder charge" (HF) was introduced and proposed as a new measure in combustion theory to analyze the combustion characteristics and air-fuel mixing process of diesel engines in more detail. The second part of this research builds upon a detail investigation on the included spray cone angle concept and explores further their use in conjunction with multiple-injection strategies in diesel engines. In addition, an investigation was performed in third phase of this research to analyze the effects of piston geometry on combustion, performance and exhaust emission characteristics. The results showed that employing a post-injection combined with a pilot injection results in reduced soot formation from diffusion combustion and enhances the soot oxidation process during the expansion stroke, resulting in decreased soot emissions, while the NOx concentration is maintained in low levels. It was also found that spray targeting is very effective for controlling the in-cylinder mixture distributions especially when it accompanied with advanced injection strategies. Moreover, the results confirmed that a narrower width of piston bowl has a higher unburned fuel air mixture region and hence results in higher soot emissions but with slightly larger piston surface area the optimum operating point could be obtained.
