An Overview of Modern Fuel Injection Strategies for Automotive Diesel LNG and Hydrogen Engines: Towards better Performance and emissions

<p>The purpose of this book is to provide consolidated insights related to the modern fuel injection system &#40;more specifically strategies&#41; and its implications on Performance (Fuel Economy Torque) emissions and combustion noise to the engineering students researchers and professional community (Automotive industry). It also focuses on the vehicle-level performance of the Engine with multiple fuel injections. The major parts of the book are the extended version of research conducted by the author during his PhD course. This book is the culmination of extensive research on multiple fuel injection strategies in combination with EGR on a medium-duty engine equipped with CRDI (Common Rail Direct Injection) technology for commercial vehicles as well as exposure to various R&D projects. It brings key insights into the Quadruple Injection Strategy which comprises double pilots (early and pilot) and one-post injection pulse in combination with high EGR-LTC on a diesel engine. The influence of multiple injection strategies upon vehicle-level fuel economy and noise performance has also been reported in this book.</p><p>Further Hydrogen and LNG-based engines are also getting attention nowadays. Globally these fuels are beneficial for reducing emissions and supporting the decarbonisation goals of the Automotive industry. The two chapters of this book provide insights into dual-fuel (Diesel -LNG and Diesel- Hydrogen) based Automotive diesel engines and their fuel injection strategies. High-Pressure Direct Injection (HPDI) technology is used here for both engines. These engines also have a Quadruple injection strategy with post-injections.</p>
