HCCI Combustion Research

A test stand for instructional and research purposes has been designed and built to investigate the homogeneous charge compression ignition (HCCI) combustion process.  A single-cylinder diesel engine (10 hp rating) was retrofitted to operate with an intake air heater and gasoline port fuel injection.  The stock piston head was redesigned to provide an adequate compression ratio for auto-ignition of the gasoline-air mixture near top dead center.  An in-cylinder pressure transducer linked to a crankangle encoder allow the engine operator to study instantaneous pressure-volume, pressure-crankangle data.  By varying fuel air equivalence ratio and intake heating characteristics, combustion stability limits are analyzed.

  • Founded by inventor, industrialist and philanthropist Peter Cooper in 1859, The Cooper Union for the Advancement of Science and Art offers education in art, architecture and engineering, as well as courses in the humanities and social sciences.

  • “My feelings, my desires, my hopes, embrace humanity throughout the world,” Peter Cooper proclaimed in a speech in 1853. He looked forward to a time when, “knowledge shall cover the earth as waters cover the great deep.”

  • From its beginnings, Cooper Union was a unique institution, dedicated to founder Peter Cooper's proposition that education is the key not only to personal prosperity but to civic virtue and harmony.

  • Peter Cooper wanted his graduates to acquire the technical mastery and entrepreneurial skills, enrich their intellects and spark their creativity, and develop a sense of social justice that would translate into action.
