During testing, engine components are examined on various test stands. Tests are carried out on the following:
- Vehicles
- Operating engines with and without brakes
- Externally-driven engines (powered by electric motors)
- Towed components
- Special test stands
The following testing methods are used to develop and approve engine elements:
- Operational strength tests
- Dynamic tests
- Function tests
- Misfire tests
- Gear-change tests
- Wear tests
- Friction measurements
- Durability tests
- Special tests
