Common Rail Diesel Fuel Injection
I.D. # C0920 Duration 1 Day

The improved efficiencies of the modern diesel engine have led to its increased use within the mobility industry. The vast majority of these diesel engines employ a high-pressure common rail fuel injection system to increase the engine's fuel-saving potential, emissions reduction, and overall performance.

This one-day seminar will begin with a review of the basic principles of diesel engines and fuel injection systems. Diesel and alternative fuels will be discussed, followed by current and emerging diesel engine applications. The majority of the day will be dedicated to the common rail system itself, beginning with a comprehensive overview of the complete system. The instructor will then introduce the main subsystems, including hydraulics and controls. Finally, the subsystems will then be broken-down into their respective components.
Learning Objectives
By attending this seminar you will be able to:
  • Identify the basic principles of diesel engines and diesel fuel injection
  • Distinguish the main properties of diesel and diesel alternative fuels
  • Compare and evaluate various diesel engine applications
  • Describe the main systems and sub-systems of common rail diesel fuel injection and how these systems interact
  • Identify the main design features of the common rail components
  • Discuss basic common rail control strategies
Who Should Attend
This course will benefit engineers and other individuals involved in the design, application, and service of common rail diesel engines utilized in passenger cars, light/medium/heavy-duty trucks, and off-highway vehicles, including marine and farm machinery.
Prerequisites
Familiarity with basic engine design and operation theory is recommended.
