Abstract

A simple mechanical CVVA system as a four-bar linkage mechanism is characterized by compactness, and it offers certain benefits in terms of adaptation to various cylinder head configurations, which is conducive to improve engine performance greatly is introduced in this paper. The CVVA mechanism consists of a four-bar linkage, a rotating first cam and two oscillating second cams in addition to the conventional overhead camshaft valve train system. The construction of the model and the dynamic analysis is also fully proposed in VALDYN software. The simulation results demonstrate that the CVVA mechanism has the capacity to sustain proper performance in the valve lift and valve timing across the whole speed range.
