Cylinder deactivation (CDA) as well as valve deactivation (VDA) technologies provides big potentials to decrease fuel consumption and emission at part load operation for SI engine. In real driving situation, an internal combustion engine operates in transient operation where the load and speed varies continuously. This part load operation leads the engine to have poor fuel consumption and emission due to throttle pumping losses. This paper will investigate the further potential of both induction strategy, cylinder deactivation and valve deactivation in extending the fuel economy at part load.
