Description	This contribution is focused on an investigation of two well-known techniques, i.e. the modified Atkinson working cycle with a late intake valve closing (LIVC) and the Miller working cycle with an extreme early intake valve closing (EIVC) in order to increase the fuel economy of a throttled SI engine at a part load (high throttled mode). A commercial 1-D code was utilized in order to calculate the in-cylinder pressure and the fuel economy improvement for both unconventional cycles with and without mixture heating. A predictive turbulent flame model for SI engine, as a part of applied 1-D code, was used for combustion calculation. Data from experiments carried out on the SI engine with the Otto cycle were used for calibration of the engine model. Based on results from simulations, a significant increase in fuel economy improvement has been observed compared to the Otto cycle, especially due to the application of the Miller cycle. Further fuel economy improvement has been achieved due to a combination of both unconventional cycles and the mixture heating.
