At present, many enterprises adopt a completely newly-built test platform/system mode to test the hybrid engine aiming at the characteristics of the hybrid engine, but the newly-built test platform/system often has the following defects:

1. research and development costs and equipment costs are required to be invested in newly building a hybrid engine test platform/system;

2. a new hybrid engine test platform/system needs a construction period and a debugging period;

3. the newly-built hybrid engine test platform/system causes the waste of the original test platform/system (used for testing the fuel engine) equipment.
