摘要
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 paper describes the hardware and software design for computer-controlled fuel injection system of the multipoint turbocharged engine.In this system the electromagnetic nozzle au-tomatically regulates and precisely revises the air-fuel ratio according to the engine operating condi-tion and vehicle running state.With this concept the system can improve fuel economy,eliminate en-gine pollution and greatly enhanee both the lift-up power and the driving performance.The control functions of the system include fuel injector pulse width,spark advanee,ignition coil dwell,electronic boost control,knock control,automatic idle speed,diagnostics,limp-in and purge.cooling fan,alternator charge rate,etc.
