pumping loss

基本解釋

Engineers call this condition a pumping loss, because in essence an engine is an air pump.
工程師稱這種情況是泵氣損失，因為發(fā)動機在本質(zhì)上是一個空氣泵。

The result is a reduction in the pumping loss under light loads, which translates to better response and fuel economy.
結果是輕負荷的泵氣損失減少，這意味著更好的響應和燃油經(jīng)濟性。

Exhaust gas trap(EGT) is more effective strategy for mixture dilution and heating, and it is beneficial to reduce pumping loss and fuel consumption than exhaust gas recirculation(EGR).
廢氣滯留比傳統(tǒng)的廢氣再循環(huán)具有更好的稀釋和加熱混合氣作用，有利于減小汽油機中小負荷泵氣損失，降低油耗。

Pumping ozone gas into four of its storage rooms reduced the loss from decay to below 2% in 2007.

泵氣損失
The traditional gasoline engine regulates inflow gas by throttle. At low load condition large pumping loss leads to high rate of fuel consumption.
傳統(tǒng)汽油機靠節(jié)氣門調(diào)節(jié)進氣流量,小負荷時節(jié)氣門開度小、泵氣損失大,導致燃油消耗率過高；配氣機構的凸輪型線固定不變,不能兼顧全部工況下的進氣需要。
