Summary:

Comparison of net thermal efficiency and emission in two and four stroke gasoline HCCI engine has been carried out for various valve-timings as negative valve overlap and exhaust valve double opening. The valve timings could easily be converted from a mode to another by configuring schedule of electromagnetic valve-train. Extension of operable torque with high thermal efficiency had been expected in two-stroke HCCI operation, however friction and supercharger loss curtailed about half of the gain in indicated thermal efficiency. In four-stroke operation modes, exhaust valve double opening (reinduction' or rebreathing') showed the best net thermal efficiency and emission, however the extension of high load limit could not be achieved considerably
