Description

<p>For the 2nd generation Skyactiv-D, we have significantly improved thermal efficiency by pursuing the ideal-state of the predominant control factors of the thermal efficiency and by the new combustion approach of evolving combustion timing and duration. With the newly developed "Distribution Controlled partially Premixed Compression Ignition (DCPCI)" using a newly devised Dual Zone Egg-shaped piston bowl, we have succeeded in the extensive application of the highly efficient and combustion-clean Premixed-charge Compression Ignition (PCI) concept to the practical medium-high load range, which had been applied only to the light load range. Focusing on the combustion technology of the 2nd generation Skyactiv-D, here we report on the function development process for improving thermal efficiency, the proposed new combustion concept based on CFD analysis, and the verification results by engine experiments.</p>
