LMS Imagine.Lab Air Path Management helps users to design all kinds of air path architectures - including exhaust systems - for any kind of technical choice. The solution provides a quick analysis of the impact of selected technical architectures (variable valve timing, turbo charging, exhaust gas recirculation, diesel particle filter). It accurately manages the air mass and burned gas ratio in the combustion chamber.
Engine technology focuses on how to maintain performance while reducing both emissions and fuel consumption. The main concern for cutting-edge engine design relates to NOx and CO2 emissions. Some of the major challenges that engineers are faced with today are accurately analyzing combustion by mastering injection and in-cylinder gas composition as well as managing optimized downsizing associated with turbo charging.
LMS Imagine.Lab Air Path Management is based on the AMESim multi-domain system simulation approach and on a set of libraries and component models, which provide the necessary tools to design advanced air path management strategies: mechanical, IFP-engine and thermal libraries, powerful analysis tools, turbo map pre-processing, linear analysis, Simulink interface, generic co-simulation to allow coupling with CFD tools.
LMS Imagine.Lab Air Path Management helps to design all kinds of configurations and provides detailed modeling of air path actuators like valves, VVT, and VVA. Moreover, with the phenomenological combustion model the impact on torque, emissions and consumption can be analyzed. Furthermore, the interaction between air path and other engine subsystems can be detailed and examined.
With LMS Imagine.Lab Air Path Management, engineers can efficiently test new technologies and designs, and take advantage of a balanced compromise between required simulation accuracy and calculation times. Finally, LMS Imagine.Lab Air Path Management directly evaluates the system’s behavior and helps to define associated control strategies when coupled to the LMS Imagine.Lab Engine Control solution. Engineers can focus on real issues rather than on the development and maintenance of engine models. The solution’s flexibility and modularity makes it possible to implement and integrate the latest technological innovations.
LMS Imagine.Lab Air Path Management has been developed in close collaboration with IFP, ensuring the delivery of cutting-edge, innovative solutions.
