What is the Difference Between Calibration and Bench Testing?
1 Answers
Simply put, calibration is a process of optimizing various control parameters of each control unit. Bench testing, on the other hand, refers to testing the quality of gasoline, engine oil, diesel, gear oil, etc., by simulating the operation process of an automobile engine. It generally belongs to large-scale projects, which require the cooperation of various instruments and equipment for data detection. Additional information is as follows: 1. Gasoline engine bench testing: The results of gasoline engine bench testing are the basis for determining the quality grade of gasoline engine oil. For example, the MS-II D engine test: used to evaluate the ability of lubricating oil to prevent rust or corrosion of the valve group under low-temperature and short-distance driving conditions, and to evaluate API, SE, SF, and SG grade gasoline engine oils. The Chinese standard test method includes SH/T-0512 gasoline engine oil low-temperature rust evaluation method (MS Procedure II D method). 2. Engine principle: Engine calibration, in the final analysis, is a process of optimizing intake, fuel injection, and ignition control. Engine matching work is to set appropriate values for various parameters of the engine control unit (ECU) through various project matches under a certain engine management system (EMS) to meet the requirements of the best air-fuel ratio and the best ignition advance angle for each working condition determined by the car's power, economy, reliability, safety, and emission performance.
