Abstract

[Valve control strategy exerts an impact on combustion and emission characteristics to a large extent through changed in-cylinder charge motions and turbulence intensity. Quite many zero/quasi-dimensional models have been proposed for the prediction of in-cylinder flow properties, as introduced in Section 2.2.1. However, these models are either targeted at gasoline engines or need further extensions to meet the latest application requirements in diesel engines, e.g., variable valve train. On these grounds, a quasi-dimensional (QDM) flow model is developed for the diesel engines with a fully variable valve train.]
