In the testing department, engine components are investigated on various test rigs. Tests are carried out on:

• Vehicles
• Fired engines with or without brakes
• Externally driven engines (driven by electric motor)
• Externally driven components
• Special test rigs

The following test methods are used to develop and approve engine components:

• Fatigue tests
• Dynamic performance tests
• Functional tests
• Misfire tests
• Switching tests
• Wear tests
• Friction tests
• Durability tests
• Special tests
