数据流分析技术在电控汽油发动机维修中的应用举例

The Data Flow Analysis Technology Using on the Electronically Controlled of Engine Maintenance

0前言 现代汽车上所配备的电控发动机是机电一体化高新技术的产物，由此给传统的汽车维修业带来了根本性的变革．给汽修从业人员提出了新的挑战。维修中，如果能将传统的维修经验结合现代专业理论知识，并借助先进的检测、维修设备，从而制定出切实可行又经济的维修方案，定能让汽修从业人员更精准更快捷地检修汽车各电子控制系统的故障，从而提高维修效率，减少维修的盲目性，节省维修时间和成本。

This article mainly introduced when diagnoses a Sangtana 2000GSI engine anxious acceleration bad breakdown,the decoder demonstrated that does not have in the breakdown code situation,utilizes the data flow analysis ingeniously and unifies the traditional service experience's way.After ruling out each kind of breakdown possibility,discovered that the breakdown is causes because of the hot film type air-flow meter signal distortion.The replacement air-flow meter and lets the engine after the study function completes,the breakdown is fixed thoroughly,has achieved the trouble clearing quick and the accurate goal.
