中文说明：基于一组发动机台架试验测到的发动机的转速，扭矩，节气门开度，燃油消耗率，以及发动机总功率的特性曲线，而且用Matlab语言制作成了发动机Map图，可以用作发动机数字建模，以及发动机的外特性等的分析。
English Description：
Based on a set of engine bench tests to engine speed, torque, throttle opening, fuel consumption, as well as total power of characteristics curve of engine and engine were made in Matlab language Map, can be used as a digital modeling of engine, and engine performance analysis.
