Fuel pump apparatus, system, and method

The disclosure relates to fuel pump apparatuses, systems, and methods. Apparatuses, systems, and methods related to high pressure fuel pumps are disclosed herein. A single plunger fuel pump for an engine may include a pump body and a plunger. The pump body may have a bore and a longitudinal axis LA extending through the bore. The plunger may be movably disposed within the bore along a longitudinal axis LA such that the plunger reciprocates within the bore. The single plunger fuel pump may be configured to have a transmission ratio between the single plunger fuel pump and the engine such that one pumping event exists for each power stroke event in the engine. 本公开涉及燃料泵设备、系统和方法。本文公开了与高压燃料泵有关的设备、系统和方法。一种用于发动机的单柱塞燃料泵可以包括泵体和柱塞。泵体可以具有孔和延伸穿过孔的纵向轴线LA。柱塞可以沿着纵向轴线LA可移动地布置在孔内，使得柱塞在孔内往复运动。单柱塞燃料泵可以被配置成在单柱塞燃料泵与发动机之间具有传动比，使得对于发动机中的每个动力冲程事件有一个泵送事件。
