液压自由活塞发动机点火系统的研制

Design of Ignition System for Hydraulic Free Piston Engine

液压自由活塞发动机是将内燃机与液压泵集成为一体的新型特种发动机。由于无曲轴—连杆等旋转部件 ,使得其点火系统与曲轴式发动机有着诸多不同。本文结合液压自由活塞发动机的结构及运动特点 ,设计了液压自由活塞发动机的基本点火电路及外围电路 ;以数字仿真为基础 ,为主要元器件结构选型及参数选择提供根据 ;并在样机的调试过程中 ,对点火系统进行了实测。仿真研究和实测结果说明了所设计的计算机控制点火系统是简单易行的。

As a special engine, hydraulic free piston engine (HFPE) integrates two internal combustion engines and a hydraulic pump into one compact unit. Comparing to conventional crankshaft engine, HFPE has significant differences because of no rotational parts. This paper deals with HFPEs ignition system, the key parameters and components are discussed and selected, based on digital simulation. Theoretical analysis and experimental measurement show the design is feasible and simple.
