液压柱塞泵共轨罕见缺点有哪些

  由共轨电控燃油放射体系的电子节制燃油放射手艺能够实此刻任何速率,高压燃油放射前提,改良发念头的功效在低速和低负载前提出格有益。因为最大许可打针压力是一个液压柱塞泵的首要局部刚度和严峻的挑选,是以,大大推动打针压力将降落在液压柱塞泵任务靠得住性题目,出格是油泵柱塞偶件过分泄露构成更高的燃油压力题目是很难成立。对共轨燃油体系的一些关头手艺液压柱塞泵的计划,停止了实际阐发,会商若何应答油泵柱塞偶件过分泄露。的根本上普遍的国际外研讨文献,高压共轨燃油体系构成、任务道理、国际外研讨近况的概述停止了阐发一切的高压共轨燃油体系的任务特色,油泵和燃油放射压力,提出有效的节制燃料泄露量的关头手艺。液压柱塞泵柱塞偶件,油泵凸轮和其余首要组件的根本上更具体的会商,基于国际现有的机器加工装备和手艺,高压油煤油供给150 mpa的压力。
