After the gear unit has been tested, it is often shipped to another factory where the whole power package is put together and tested. The power package involves a prime mover, a gear unit, and a driven unit. Some examples are the following: Turbine, gear unit, electric generatorTurbine, gear unit, compressorDiesel engine, gear unit, pumpElectric motor, gear unit, fan

The ambient temperature was chosen as 827, 806, 787, 768, 745, 725, 707 K to mimic the cold start in-cylinder environment with different injection timing, different environmental temperatures, cycles at different starting stages, and engines with different compression ratios. The injection pressure was chosen at 60 MPa, which is a typical level of electronic unit pump used in heavy duty diesel engine. The ambient density was kept at a typical diesel engine TDC cylinder gas level, 13.5 kg/m3.
