What does engine running-in test include?
1 Answers
Engine running-in generally consists of three stages: cold running-in, hot running-in, and dynamometer testing. The following is relevant information: 1. Cold running-in: Cold running-in uses external force as the power source to systematically vary and increase the speed and load on the engine's main working components under sufficient lubrication conditions. 2. Hot running-in: Hot running-in uses the intact engine itself as the power source and systematically varies the speed and increases the load under its own working conditions until reaching the rated power and rated speed. 3. Dynamometer testing: Dynamometer testing measures the specific fuel consumption and power of the engine at rated speed conditions to evaluate the quality of engine assembly, manufacturing, or repair.
