Description

technical field

[0001] The invention belongs to the field of supercharger measurement and control, and in particular relates to a supercharger rotational speed monitoring record and early warning device and early warning method. Background technique

[0002] The main function of the supercharger is to increase the air intake of the engine, so as to achieve the purpose of increasing power, improving economy, and improving emissions. In recent years, the use of superchargers has been continuously upgraded with the increasing demand for engine power in OEMs. At the same time, the upgrade of emission standards has also led to a substantial increase in the market share of superchargers. Whether the performance of the supercharger is stable or not directly affects the smooth operation of the engine, so the supercharger has become an important part of the complete engine. At present, the domestic supercharger speed test device only has the function of monitoring the real-time speed...
