Direct Injection Systems for Spark-Ignition and Compression- Ignition Engines

The book presents both a synthesis of modular concepts based on function characteristics and a system classification following the physical model. Topics are focused on the injection system itself, and specific technical solutions for new concepts are concretely described.

Chapters cover:

• Direct Injection as Element of the Mixture Formation Concept
• Direct Injection Methods - Physical Possibilities and Limits
• Direct Injection of Liquid Fuel with Damped Speed Influence on the Pressure Wave
• Direct Injection of Liquid Fuel with Quasi Constant Maximum Pressure
• Direct Injection of Liquid Fuel with Speed Independent Pressure Modulation
• Direct Injection of Fuel/Air Pre-Mixture with Mechanical Flow Control
• Direct Injection of Fuel/Air Pre-Mixture with Electronic Flow Control
• Injection Law Modulation
• Injection Systems with Speed Dependent Injection Law
• Injection Systems with Accumulated Fuel High-Pressure (Common Rail)
• Injection Systems with Speed Dependent Pressure Wave and Variable Flow Passage
• Injection Systems with Speed Independent Modulation of the Pressure Wave
• Injection Systems for Alternative Fuels
