Abstract:

The engine position synchronization was the basic of the fuel injection system.Based on the situations of the normal work and “ lamp home”,this paper researched in the signal checking,the design of synchronization policy,and software implementing.The first focused on the correct of signal;the second concentrated the real-time and efficiency of the algorithm;and the third met the low coupling requirement of cooperation components.Therefore,there was a test in project,which gave the evidence to the practicability of the method.

Key words: position synchronization;crank signal;cam signal;lamp home
