phenomenon of chokingとは 意味・読み方・使い方

To solve the problem of deteriorating efficiency in exhaust gas by causing a choking phenomenon when an exhaust flow speed reaches a sound speed in a period for reducing a lift quantity of an exhaust valve since combustion gas flows at a high speed on the periphery of the exhaust valve in an initial blow-down process of an exhaust stroke.例文帳に追加

排気行程当初のブローダウンの過程では排気弁の周囲を高速で燃焼ガスが流れるため、排気弁のリフト量が少ない期間では排気流速が音速に達してチョーキング現象を起こし、排気の効率を悪化させる。 - 特許庁
