四冲程内燃机作功过程分析仪设计

The Designing Theory for the Working Analytical Instrument of a Four Stroke Internal combustion Engine

四冲程内燃机作功过程分析仪是一种能使人们准确、迅速、直观地了解和掌握四冲程多缸内燃机各缸在任意指定时刻下的工作状态，并且由工作状态确定气门开闭状态的一种新仪器。就此论述了该分析仪的设计原理和工作原理以及设计的合理性。

The working analytical instrument of a four stroke internal combustion engine is a kind of new instrument that can make people understand and grasp the working contents of each cylinder of the four stroke multi cylinder internal combustion engine properly,quickly and directly at any appointed time.It can determine the condition of valve opening or closing by working contents.This theory discusses the analytical instrument reasonably in designing,reliability in working and feasibility in technology.
