	abstract = {Turbocharged engines exhibit the so called turbo lag phenomenon causing a disadvantageous response comparing to atmospheric or mechanically supercharged engines. There are many solutions developed to reduce the lag effect although each of them has some disadvantages. This paper investigates a booster module that injects compressed air to increase the response of turbocharged compression ignition engines of commercial vehicles. The investigations applied 3D computational fluid dynamic (CFD) simulations in stationary and transient manner as well. The transient simulations were applied as standalone and coupled calculations to a 1D engine simulation code to capture more accurate boundary conditions (BC). The drawbacks and problems of this new and advanced approach are emphasized in the paper. Due to the deformation of the flow field boundary surface during the dynamic process a deforming mesh method has been applied here. Instant shape of flow field boundary has been obtained by solving the equation of motion of the actuator rotor. By applying the above methods it was possible to validate the booster module design variants and to identify the main characteristics of the complete system including the engine.},

This paper presents a flexible computational simulation tool being applied in industrial research and development related to complex mechanical and fluid dynamical aspects in such devices. The numerical model has been created with AMESim, a commercial simulation environment, and then validated by simplified experiments. The comparative numerical and experimental study confirmed that the validated numerical model is able to predict the oscillatory behavior appearing in certain setups, and the system parameter alterations suggested by the simulation successfully eliminated the harmful vibration in the experimental setups as well.},

	abstract = {Electro-pneumatic (EP) components are frequently used in brake systems of commercial vehicles. The simulation of EP brake systems is of great importance in order to understand their dynamics for developing a control logic being robust but fulfilling the modern functional demands. On the other hand, the simulation aids the design of EP components being able to execute the commands of a precision control. The paper presents a flexible computational simulation tool being applied in industrial research and development related to complex mechatronics in brake systems for commercial vehicles. The Electric Braking System (EBS) case study presented herein comprises an air supply unit, an EBS modulator, piping, a diaphragm brake chamber, and the connected brake mechanism. The simulation environment is AMESim® 3.0. Considering the complexity of the EP components and the related phenomena, special models have been elaborated for the solenoid valves, piping, and the diaphragm brake chamber. The simulation results show good agreement with measurement data. The comparative numerical and experimental study confirmed that the simulation tool can be effectively used in design, research and development of EP brake systems.},
