When we apply more efficient combustion profile using advanced mechanisms to ICEs, vehicles with ICEs can exceed BEVs from the view of total environmental performance. This paper illustrates SimulationX, a Modelica simulation tool, can be a tool for the developments of advanced mechanical systems such as new valve trains and cranking systems. This paper also shows a case of FMI co-simulation of a cam phaser between the tool and another hydraulic simulation tool which is used to model a conventional hydraulic system of an existing ICE.
