摘 要：長缸試漏測(cè)試是發(fā)動(dòng)機(jī)制造領(lǐng)域常用的成品出廠質(zhì)量檢測(cè)手段，用于對(duì)發(fā)動(dòng)機(jī)總成水通道及油通道進(jìn)行試漏檢測(cè)，以評(píng)估其密封性能。壓降法及質(zhì)量流量法是氣密性檢測(cè)的兩種常用方式，被廣泛應(yīng)用于長缸試漏測(cè)試領(lǐng)域，本文探索兩種方式的測(cè)試原理，并研究其在長缸試漏中的優(yōu)劣及應(yīng)用前景。

Abstract：Long-block leakage test is a common method to detect engine function before unloading， test include water system and oil system hermetic detection. Pressure drop and mass flow are primary methods in this field. Thesis apply itself to explore principle of them， and research merit and demerit in Long-block leakage test station.

1 長缸試漏檢測(cè)介紹

在發(fā)動(dòng)機(jī)運(yùn)行過程中，機(jī)油對(duì)發(fā)動(dòng)機(jī)內(nèi)部運(yùn)動(dòng)部件進(jìn)行潤滑，實(shí)現(xiàn)減少磨損、清潔零件以及降溫的目的。（剩余4880字）
