In this paper, we utilize current equipments such as dynameter and specific fuel consumption detector, and design a set of engine test bench platform based on P89C668.

根据台架试验试平台基本要求,充分利用了、油耗仪等原有备,开了基于P89C668台架试验试平台,实现了显示、打印、控制和通讯等能。

The bench test results indicated that the metering quality of the dibbler was increased significantly after improvement.

台架试验结果表明，穴播器经改进后对棉种播种精度有了较大提高。
