(c) The 'dual combustion' or composite cycle (Figure 1.7c)
(c) 雙燃循環(huán)或復(fù)合循環(huán)（圖1.7c）
This represents a combination of the constant pressure and constant volume cycles and is intended to provide a closer approximation to actual diesel cycles than either of the above ideal cycles.It is particularly appropriate where comparisons are to be made with actual diesel cycles on the basis of the maximum cylinder pressure max obtained during the heat release period,i.e.for engines operating in the mid-to full load range.
這代表著一種恒定壓力和等容循環(huán)的結(jié)合,打算用來提供一個比以上任何理想循環(huán)更接近現(xiàn)實(shí)柴油機(jī)循環(huán)的數(shù)值.它特別適用于做比較的地方,在熱釋放期根據(jù)獲得的最大汽缸壓力與現(xiàn)實(shí)柴油機(jī)循環(huán)做比較,比如：在中等負(fù)荷范圍內(nèi)運(yùn)轉(zhuǎn)的發(fā)動機(jī).
