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?yàn)榘l(fā)動(dòng)機(jī)在本質(zhì)上是一個(gè)空氣泵。

The result is a reduction in the pumping loss under light loads, which translates to better response and fuel economy.
結(jié)果是輕負(fù)荷的泵氣損失減少，這意味著更好的響應(yīng)和燃油經(jīng)濟(jì)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(jī)中小負(fù)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(jī)靠節(jié)氣門調(diào)節(jié)進(jìn)氣流量,小負(fù)荷時(shí)節(jié)氣門開度小、泵氣損失大,導(dǎo)致燃油消耗率過高；配氣機(jī)構(gòu)的凸輪型線固定不變,不能兼顧全部工況下的進(jìn)氣需要。
