Engine design controls

Internal combustion engine system simulation

Develop internal combustion engine systems and controls.

Accurate physical engine and component models

Evaluate, design and optimize complete internal combustion engine systems, from air management and combustion to exhaust after-treatment and engine controls, by using accurate physical engine and component models. The capabilities for internal combustion engine simulation are developed in close collaboration with IFP Energies nouvelles.

By applying a system simulation approach using Simcenter, you can now study integration with fuel injection subsystems, engine thermal management, electrical devices, powertrain and various other components, as well as adapt model definitions to a wide range of scenarios. Simcenter allows you to analyze the impact of advanced technology choices and gives you a powerful toolset to investigate alternative engine architectures and concepts.

Internal combustion engine system capabilities

Air path & charging

Develop innovative air path architectures, including actuators, charging and cooling systems, and rapidly analyze their impact on gas management, combustion and emissions. In addition to a broad set of component models that enable you to design advanced air path systems and study the engine performance, Simcenter provides powerful application-oriented analysis tools, a Simulink interface, and generic co-simulation to allow integration with computational fluid dynamics (CFD) software.

Combustion

Offer your customers better engine response and lower fuel consumption. Simcenter supports the design and optimization of conventional and innovative combustion processes as well as the adoption of alternative fuels. You can optimize engine parameters, such as spark advance, turbulence, lambda control or injection split for different fuel types and assess the benefits in terms of efficiency, torque production and emissions.

Engine controls

Address the growing complexity of engine control strategies using the multiphysics plant modeling capabilities of Simcenter. Engine control engineers in charge of controls design, validation (offline or real-time) and calibration can use the state-of-the-art Simcenter engine, after-treatment and powertrain models at every development stage. An efficient Simulink interface and straightforward export workflows ease the integration of the models in your processes.

Exhaust after-treatment

Meet emission standards including Real Driving Emissions (RDE) by optimizing exhaust systems and associated control strategies. Simcenter allows you to accurately model and analyze the conversion of nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HC) and soot filtration. You can work on exhaust system components and controls and integrate the after-treatment system in a vehicle configuration in order to evaluate the emissions for driving cycles.
