Strict emission limits have forced the automotive industry to reduce the carbon dioxide emissions produced by internal combustion engines. Emissions can also be reduced by increasing the efficiency of internal combustion engines by implementing technologies such as cylinder deactivation, the main benefit of which is a reduction in fuel consumption. However, there are some negative effects associated with this technology. There are two approaches to cylinder deactivation - selective and rolling. This paper focuses on the constraints of the technology and compares the two methods of cylinder deactivation in terms of torsional vibration, friction losses and load on the main bearings. The results for the selective and rolling cylinder deactivation are obtained from a verified multibody simulation of a four-cylinder engine.
