电控多点汽油喷射控制系统的研究

本文介绍了一种单片控制的多点电控汽油喷射系统。该系统不仅具备适应发动机各种工况变化的燃油控制功能，具有明显的降低排气污染、节油和提高动力性的效果，还能对系统的故障进行自我诊断。本文详细介绍了系统的工作原理、结构、软件硬件设计及脉普谱图的测取方法，并给出了试验结果。

The Research of a Microprocessor Controlled Multi-point Fuel Injection System for Gasoline Engines

In this paper, a single-chip microprocessor controlled MPI system is described. The MPI system not only has the ability to control fuel supply accurately for most engine operating modes so as to improve fuel economy, exhaust emission and engine performance considerably, but also can perform selfdiagnosis. The principle, construction, software and hardware development of the system and the way of engine mapping are discussed here in detail and test results are also provided.
