| 摘要： | 本发明属于车辆控制技术领域，特别涉及一种发动机VVT系统的检测方法，包括如下步骤：将同一型号发动机两套以上的VVT系统放置在台架上，匹配同样的缸盖油道、VVT电磁阀，将发动机热机使得机油温度为100℃-120℃；对VVT系统的响应性、稳定性和跟随性进行检测，剔除不满足要求的VVT系统；余下的VVT系统即为与该发动机相适配的VVT系统。从发动机开发与整车匹配层面综合考虑了VVT系统机械与控制方面的优劣与检测方法，保护发动机VVT系统安全性，使得车辆上所装配的VVT系统更匹配、工作更可靠。另外这里还并公开了该系统的控制方法，避免VVT系统工作在偏差较大的工况下。 | ||
| 摘要(英文)： | The invention belongs to the field of vehicle control technology, in particular to a method for detecting VVT system of the engine, comprising the following steps : the same type of engine more than two sets of the VVT system is placed in the rack, matching the same cylinder head oil gallery, the solenoid valve VVT, heat of the engine makes the engine oil temperature is 100 °C -120 ° C; responsiveness of the VVT system, for detecting the stability and follow-up, the requirements of eliminating unsatisfied with VVT system; the remainder of the VVT system is matched to the VVT system of the engine. Development and the matching of the engine taking into consideration the level of mechanical and control VVT system and method for detecting the quality of, the safety protection of the VVT system of the engine, the on of the vehicle to more closely match the VVT system, the work is more reliable. In addition here also and disclosed the control method of this system, avoid VVT system to work in the working condition of the deviation is greater. | ||
