Engine Mechanics and Computation

We use cutting-edge methods and tools for designing, computing and testing engines and components for application in commercial vehicles

Developing new and advancing existing commercial-vehicle engines normally demands optimizing efficiency while sharply reducing emissions. We do this using perfected methods and state-of-the-art facilities.

Computational analysis, component layout and simulation of strength/stiffness, kinematics/kinetics, dynamics, material behavior, acoustics, gas exchange, combustion process, cooling system, intake system, mixture formation and exhaust gas system are firmly established as integral components in the engine development process at IAV.

Our activities in developing engine mechanics focus on optimizing structures, saving weight and reducing friction. In heavy-duty engines today the trend is toward downsizing and downspeeding while increasing in-cylinder peak pressure. Here, we offer our clients constructive solutions.

Our experienced development engineers use numerical design and simulation techniques, such as the finite-element method (FEM) and multi-body simulation (MBS). To conduct powertrain studies of a more complex nature, we generate MBS models for simulating every aspect of 3D multi-body engine-component dynamics while incorporating elastic bodies from FEM modeling. The portfolio is complemented by state-of-the art machinery for producing everything from individual assemblies to full prototype engines.

We validate components, subsystems, engines or the entire powertrain on our own test facilities. These include:

  • Component test benches for injection systems, flow visualization, coolant circulation, mechanical components, turbocharger, air-conditioning system, heating etc.
  • Engine dynamometers
  • Single-cylinder test bench (external charge-air system and conditioning)
  • Indoor commercial-vehicle bay for providing support with test and fleet vehicles
  • Commercial-vehicle roller dynamometer
  • Climate chambers
