本文阐述计算机控制多点增压发动机燃油喷射系统的硬件、软件设计。计算机控制电磁喷嘴的喷油量比惯用的车用化油器更精确，它根据发动机运转工况和汽车运行状况，能自动调节和精确修正空燃比，从而使系统不仅改善燃油经济性，而且消除排放污染，并且大大提高升功率和驾驶性能。系统控制功能包括：燃油喷油量、点火提前、，点火线圈储能、电子增压控制、爆震控制、自动怠速、诊断与备用模式及其他辅助控制等。
This article describes the computer-controlled multi-point engine fuel injection system hardware and software design. The amount of fuel injected by the computer-controlled electromagnetic nozzle is more accurate than the conventional carburetor, which automatically adjusts and precisely corrects the air-fuel ratio based on engine operating conditions and vehicle operating conditions so that the system not only improves fuel economy but also eliminates Discharge pollution, and greatly improve the power and driving performance. System control functions include: fuel injection, early ignition, ignition coil energy storage, electronic boost control, knock control, automatic idle, diagnostic and backup modes, and other auxiliary controls.
