1974年,Bryce Berger公司开始设计和研制一种用于缸径为200～300毫米柴油机的高喷油率喷油泵,据称此泵于八十年代初可付之应用。然而关于喷油装置需要的市场调查报道说,到那个时候,发动机制造厂一般都不愿研制完全新型的发动机,而是从现有机型的稳步发展中取得更大的功率,预料在缸径为240～260毫米的机型的研制中,会出现一个功率大幅度提高的阶段。现有的某些发动机已从平均有效压力(P_e)为6巴时使用FCOAB喷油泵,发展到P_e为14巴或14巴以上时使用FCCAB喷油泵,它们正准备在将来把P_e提高到23巴。因此当发动机功率提高时,首先需要一种新型泵取代FCCAB泵。显然,这新型喷油泵也要考虑到其主要安装尺寸(例如泵的高度、法兰安装尺寸和控制杆位置)必须能与FCCAB泵互换,以避免发动机设计的修改。据估算,喷油泵的最大供油量约2,500毫米~3/每次喷射,足以使发动机功率提高到260～300千瓦/缸。而且,在使用粘度达雷氏1号1,500秒、预热到100℃的重油,并且最高供油压力为1,200巴的情况下,这种喷油泵必须能连续工作而不
In 1974, Bryce Berger began designing and developing a high injection rate injection pump for use with 200- to 300-mm-bore diesel engines, which was said to have been available since the early 1980s. However, market research reports on fuel injection equipment reported that by that time, engine manufacturers were generally reluctant to develop completely new engines, but to obtain more power from the steady development of existing models, 240 ~ 260 mm in the development of the model, there will be a significant increase in power stage. Some of the existing engines have used FCOAB injection pumps from an average effective pressure (P_e) of 6 bar to FCCAB injection pumps up to P_e of 14 bar or above, which are being prepared to raise P_e to 23 bar in the future . Therefore, when the engine power increases, the first need to replace a new type of pump FCCAB pump. Obviously, this new fuel injection pump also needs to consider that its main installation dimensions (such as pump height, flange mounting dimensions and lever position) must be interchangeable with the FCCAB pump to avoid engine design changes. It is estimated that the maximum fuel injection pump about 2,500 mm ~ 3 / injection, enough to make the engine power increased to 260 ~ 300 kW / cylinder. Furthermore, with a heavy oil preheated to 100 ° C with a viscosity of 1,500 s of DARLYZ No. 1 and a maximum supply pressure of 1,200 bar, the fuel pump must be able to work continuously
