POWER AND PROPULSION
• Estimate and predict effects of key engine design and operating conditions on performance, combustion, and emission in GDI engines • Communicate effectively with engineers working on fuel injection, combustion and emission aspects of the GDI engine in your firm or with customers • Effectively contribute to the design of critical components such as combustion chambers, injectors, and emission reduction strategies • Explain and utilize trade-offs between increasing engine performance and maintaining low emission characteristics Who Should Attend This seminar will be especially valuable for engineers, technical and project managers, researchers, and academicians. Engineers working on the design of components for high efficiency and performance of GDI engines as well as those directly and indirectly involved in mixture preparation and emission reduction of harmful pollutants from these engines will highly benefit from this course. Environmental engineers desiring to expand their understanding of fuel spray formation, combustion and emissions from GDI engines will benefit, as well as, engineers active in the development and application of software for the modeling and design of combustion chambers, fuel spray dynamics, combustion and emission issues. Prerequisites Attendees should have general knowledge of engine operation especially in-cylinder combustion processes. However, a very concise review of the subject is presented.

Gasoline Direct Injection (GDI) Engines 3 Days | Classroom Seminar I.D.# C1009 The quest for more efficient, smarter, and environmentally cleaner liquid-fueled spark ignition (SI) reciprocating engines is more alive and intense now than ever before. GDI SI engines have overcome many of the original limitations and are now becoming commonplace. This seminar will provide a comprehensive overview of GDI engines. Mixture preparation and the combustion process, with an emphasis on strategies for both homogenous and stratified charge operation and control, including issues related to the direct injection of gasoline into the combustion chamber, and fuel injection system requirements for optimal spray characteristics will be explored. Emission of pollutants, fuel economy and effects of some key design and operating parameters will also be covered. The seminar concludes with an overview of a select list of production and prototype GDI engines. Learning Objectives Upon completion of this seminar, you will be able to: • Describe the rationale behind the GDI engine operation • Analyze the important processes in GDI engines • Explain liquid atomization, sprays, and injector requirements for successful GDI operation • Utilize the technology and the logic behind gasoline direct injection
