本文叙述扫气预燃室式单缸分层给气发动机的基础研究。特别注意排放物与燃油消耗之间的关系,除火花点火发动机典型的运转参数空燃比和点火定时等以外并研究了通过辅助进气门的燃油和质量流量的影响,燃烧室的几何形状是燃烧过程中的主要的附加参数。介绍了无量钢参数如预燃室通道尺寸和预燃室通气系数。以便以更一般的形式给出其结果,与一般火花点火发动机得出的结果进行了比较。
This article describes the basic research of scavenging pre-combustion chamber single-cylinder stratified-feed gas engine. Special attention is given to the relationship between emissions and fuel consumption, in addition to the typical operating parameters of the spark-ignition engine, such as air-fuel ratio and ignition timing, and the effects of fuel and mass flow through the auxiliary intake valve are studied. The combustion chamber geometry is burned The main additional parameters in the process. Infinite steel parameters such as prechamber passage size and pre-chamber venting coefficient are introduced. So as to give the result in a more general form, compared with the result obtained by a general spark-ignition engine.
