Numerous customer projects prove it: Our experts can provide support in developing engines from initial concept studies to the start of production and after a vehicle goes on sale – from the single-cylinder engine to commercial-vehicle application. To do this, we have four teams of specialists.
This team attends to all aspects of engine mechanics, such as the dynamics of valve train, timing gear and engine-component friction – we can measure all components and entire engines with extreme precision on our friction-loss test bench. We have a unique test bench for conducting primary research on friction bearings: This is where we can analyze individual friction bearings in isolation under loads similar to those encountered in the engine. The results are channeled into developing IAV’s own simulation tools.
Engine Function Systems
This team examines cross-component systems, such as the oil, cooling and ventilation circuits – even under the harshest of climatic conditions. On our low-temperature test bench and our low-temperature roller dynamometer, engines must demonstrate that their systems also work perfectly at low temperatures. We also develop these mechatronic systems, including the interfaces to the engine electrics and calibration – from component testing to validation in vehicle tests.
Endurance Testing and Exhaust System Development
This team can also examine and test individual components or entire vehicles. For example, manifolds, turbochargers and catalytic converters must prove on our test benches that they still perform properly after many thousands of miles. We have encountered the particular aspects of hybrid powertrains with their specific load profiles in many projects.
Acoustics and Vibration
On our acoustics test bench we locate individual noise sources inside the engine and identify those components that give rise to unwanted noises and vibrations. Together with our colleagues from Design and Computation, we develop countermeasures to find the optimum engine sound.
