Homogeneous Charge Compression Ignition Engines     


I.D.# C1010Printable Description
Duration: 2 Days

The potential benefits of the Homogeneous Charge Compression Ignition (HCCI) engine are numerous and have the potential to combine some of the best features of the Compression Ignition engine with that of the Spark Ignition engine. These benefits include overall engine efficiencies available with compression ignition and the substantially lower emissions of PM and NOx available with spark ignition systems. However, the commercial viability and wide-spread use of the HCCI engine has been slow to materialize due to significant technical challenges.

This two day seminar will provide attendees a comprehensive overview of the benefits of HCCI combustion and the main challenges to its acceptance and use in vehicles. Current technologies will be examined along with recent developments in HCCI engines. The characteristics of several commercial engines that use HCCI combustion during a portion of their operating range and the future directions for HCCI research will also be examined.

Learning Objectives
By attending this seminar, you will be able to:

  • Evaluate the benefits of HCCI combustion
  • Identify the primary challenges in the development of commercially viable HCCI engines
  • Identify recent developments in HCCI technology
  • Describe the characteristics of several commercial engines that use HCCI combustion during a portion of their operating range
  • Evaluate current research being performed and with support from governmental agencies
