一、概述 EQ140型汽车在实际使用中,EQ6100发动机缸体曾发生过早期开裂的现象。有关人员在进行了大量检查和分析研究之后指出:严重超转速使用是造成这种损坏的主要原因之一。在这种形势下,研制一种小巧价廉、工作简便的发动机限速器就成为一个意义十分重大的课题。显然,在汽车电子技术一日千里飞速发展的今天,采用电子方法以取代传统的机械方式来完成这一课题任务才是唯一正确的选择。 First, an overview EQ140 type car in actual use, EQ6100 engine block had occurred early cracking phenomenon. After conducting extensive inspection and analysis studies, the relevant personnel pointed out: Severe over-speed use is one of the major causes of such damage. Under such circumstances, it has become a very significant issue to develop a small and inexpensive engine speed limiter with simple workmanship. Obviously, in today’s rapid development of automotive electronics technology, the use of electronic methods to replace the traditional mechanical methods to complete this task is the only correct choice.
