一种天然气发动机控制器的空气系统模块的计算与控制模型设计

Calculation and Control Model Design of Air System Module of a Natural Gas Engine Controller

以天然气为燃料的发动机在某些领域被广泛使用。基于此,开发了天然气发动机的控制系统,在控制系统应用层软件中,进气量与充气效率的计算与是重要的一环。本文以物理模型为基础,以进气压力传感器的信号为输入,研究设计了天然气发动机控制系统的充气效率与进气量计算模块。

Natural gas fueled engines are widely used in some fields.Based on this,the control system of natural gas engine is developed.In the application layer software of the control system,the air intake and charge efficiency is an important link,and the control accuracy depends on the calculation of the current charge efficiency.Based on the physical model and the signal of intake pressure sensor,this paper studies and designs the charge efficiency and intake volume calculation module of the natural gas engine control system.
