摘要： A method for calibrating an engine is provided. The engine includes a cylinder for combustion of a fuel. The method includes setting combustion parameters of the engine, detecting a combustion noise during combustion proximate to the cylinder, detecting an engine sound radiated from the engine during combustion, adjusting the combustion parameters and repeating the steps of detecting a combustion noise and detecting an engine sound. The method further includes generating a relationship between the combustion noises and the engine sounds, determining a combustion noise level that correlates to a predefined engine sound threshold from the relationship, adjusting a speed of the engine and a load on the engine and repeating the previous steps to determine a combustion noise level for each engine speed and engine load setting, and calibrating the engine using the combustion noise levels.
