常見例句雙語(yǔ)例句The effects of different motoring times, motoring torques and fuel supply on the starting process of diesel engine are analyzed based on instantaneous rotation speed.試騐結(jié)果表明利用瞬時(shí)轉(zhuǎn)速能夠判斷柴油機(jī)著火首循環(huán)以及輔助分析燃燒組織的優(yōu)劣。But the fuel starting injection pressure will turn low gradually when the operational time of the diesel engine increases. This will cause worsening of the combustion process and fuel economy.但是隨著柴油機(jī)使用期的增長(zhǎng)，啓噴壓力會(huì)逐漸降低，導(dǎo)致燃燒過程惡化，經(jīng)濟(jì)性下降。The engine transient speed, fuel injection, combustion process and the cyclic variations in some performance indexes are investigated on a small single cylinder diesel engine during cold-starting.測(cè)量分析小型手搖起動(dòng)柴油機(jī)冷起動(dòng)過程的瞬時(shí)轉(zhuǎn)速、噴油及燃燒過程特征蓡數(shù)在每一循環(huán)中的變化情況； 返回 diesel starting fuel
