摩托车台架实验空燃比控制系统的开发

Designation of A/F Control System For Motorcycle Bench Test

本文介绍了用于摩托车台架实验的空燃比控制系统,可用于在台架上进行摩托车催化器性能的考核。系统主要分为上位机和下位机两部分,下位机控制喷油时刻喷油持续期及喷油量,从而实现了对空燃比的控制;上位机可以完成各种参数的监测和采集。

An A/F control system used to evaluate the performance of automobile catalytic converter on bench is introduced in this paper. The system is made up of Host-computer and Slave-computer. Fuel injection timing and fuel injection impulse can be adjusted by Slave - computer and it can also control fuel injection. The adjusted parameter can be monitored by Host - computer, also the sampling of all the parameter can be completed by it. The constitution, principle and application is introduced in this paper.
