In this paper, the necessary grey sns nails in-cylinder conditions for the transition from spark ignion (SI) to homogeneous charge compression ignition (HCCI) are analyzed.The hereby important factors for ignition time are investigated analytically.A control oriented combustion model, that is validated by experimental data, is used for sensivity analysis and a Monte-Carlo approach is taken to identify the important factors for transient HCCI and combustion mode switch.As a result, it was shown that the in-cylinder temperature plays a major role, exceeding other factors, such as the air-fuel ratio.The analytical conclusions are illustrated by numerical simulations after which the feasibility for actuation will be discussed.
Final goal knesko coupon code is to ensure a stable combustion in each cycle without crossing unstable combustion conditions.
