Gasoline Direct Injection
Saturday, November 16, 2024: Garage GURUs Trailer
Duration: 4 hours
The demand for more efficient, smarter and environmentally cleaner liquid-fueled spark ignition (SI) engines is a primary focus of today’s vehicle manufacturers. GDI SI (Spark Ignited) engines have overcome many limitations and are now becoming commonplace. This workshop provides a comprehensive overview of GDI engines. Various engine operating modes (start-up injection, late injection, operating mode transition) are explored. An explanation of mixture preparation leading to the combustion process is outlined. An emphasis on operational strategies for both homogenous and stratified charge fuel control is reviewed. Issues related to the direct injection of gasoline into the combustion chamber are highlighted. Fuel injection system requirements for optimal spray characteristics are discussed. Emission of pollutants, fuel economy and effects of some key design and operating parameters are also covered. After completing this workshop, the student will have the knowledge to:
- Describe the operating characteristics behind GDI engine operation
- Analyze the important criteria leading up to maximum performance in GDI engines such as proper operation of the Fuel Delivery system
- Explain injector spray and atomization requirements for successful GDI operation
- Utilize service tools and techniques to properly disassemble and reassemble GDI fuel systems
- Analyze important scan tool data parameters in verifying proper GDI engine performance
- Understand effects of key engine design and operating conditions on performance, combustion, and emission within GDI engines
