Injection System
Abstract
Author: Hu Shengchuan
Tutor: Zhou Dingwu
This paper mainly for the Audi A6's structure and working principle of a detailed analysis, first introduced through a number of works out of the Audi A6 electronic fuel injection system for us that some of their original understanding. Secondly, the paper also through the presentation of the Audi A6 in actual test some of the problems found in the analysis, and describes the relevant statistics for our reference and use their own methods to solve problems of them. In this paper, the end, I would also rule out the Audi A6 how to diagnose faults with some suggestions.
