Peng's project was awarded £200,000 (about $377,350) for 27 months of research on HCCI technology. Both Caterpillar and BP are backing the project while additional funding will be provided by the U.K.'s Department of Trade and Industry (DTI).
Peng expects to have a working prototype by the end of 2008, however, he summarizes HCCI's current obstacles as three-fold:
- Providing the right temperature and pressure for combustion
- Achieving a high load while avoiding knocking
- Determining the best way to start the engine, especially from cold.
