MAN-B&W 20/27 DG 型柴油沼气发动机可作为船用主机、辅机及其它用途。其主要参数如下:四冲程,定压增压,中冷,缸径200 mm,行程270 mm,直列式有4、5、6、7、8、9缸,V 形有12、14、16、18缸;燃烧柴油时,单缸功率90 kW,转速1000 r/min,耗油率202g/(kW·h),热效率42%;燃烧沼气(甲烷100%)时,单缸功率81kW,转速900 r/min,耗气率8800 kJ/(kW·h),引燃柴油量单缸1.5 kg。起动时先烧柴油,调速器控制喷油泵,并使沼气阀处于关闭状态。待沼气达到一定压力和增压空气达到一定温度,就可改烧沼气。此
MAN-B & W 20/27 DG diesel gas engine can be used as marine engines, auxiliary engines and other purposes. The main parameters are as follows: four-stroke, constant pressure booster, cold, bore 200 mm, stroke 270 mm, inline 4,5,6,7,8,9-cylinder, V-shaped 12,14,16,18 The single-cylinder power is 90 kW, the speed is 1000 r / min, the fuel consumption is 202 g / (kW · h) and the thermal efficiency is 42% when burning diesel. When the methane is burned (methane is 100% / min, the gas consumption rate is 8800 kJ / (kW · h), and the amount of diesel fuel is 1.5 kg. Start the first burn diesel, governor control injection pump, and the biogas valve is turned off. When the biogas reaches a certain pressure and the pressurized air reaches a certain temperature, the biogas can be changed. this
