摘要
针对单项发动机动态测功设备存在精度有限等问题,提出了基于MC9S12XS128MAA的发动机动态测功仪设计方案.利用发动机转速传感器和冷却液温度传感器检测发动机运行参数,利用键盘输入发动机转动惯量,单片机依据发动机动态测功原理计算出发动机功率,并在液晶显示器显示,实现测角加速度和测加速时间2种方式测功.
In view of the problems of the existing single engine dynamic dynamometer equipment,such as few kinds and limited precision,a dynamic dynamometer design scheme based on MC9 S12 XS128 MAA is given. This scheme using the engine speed sensor and coolant temperature sensor detection engine operation information,using the keyboard input moment of inertia of the engine,single chip microcomputer calculates the power of the engine according to the principle of dynamic power measurement of the engine and displays it on the liquid crystal display. The dynamometer can measure work in two ways： angular acceleration measurement and acceleration time measurement.
