Our University, University of Windsor has an HCCI research team which is funded by GM. I knew one of the research/graduate assistants who was working on that. In one of our 3rd year courses, we actually had a class dedicated to it. The setup is huge, and they are using a modified 3 cylinder Indirect Injection GM diesel engine (He told me that the 4th cylinder was disabled, can't remember why though). Since it was a test setup, they said it took them almost 2 hours to start it up (adjusting the sensors, air/fuel ratio etc.) and it's also one of the major drawbacks of the engine. Otherwise, if they can get it right, it'll be a very efficient engine. |
