Abstract: A system and method for detecting pressure deviation of a first fluid in an engine is disclosed. The method may comprise calculating, for each of a plurality of measurements, a delta between an actual first fluid pressure and a target pressure, summing each delta obtained from the calculating, and determining pressure deviation of the first fluid based on a cumulative sum of the deltas. In an embodiment, the first fluid may be natural gas.
Abstract translation: 公开了一种用于检测发动机中的第一流体的压力偏差的系统和方法。 该方法可以包括对于多个测量中的每一个计算实际的第一流体压力和目标压力之间的增量，对从计算得到的每个增量求和，并且基于所述第一流体的累积和来确定第一流体的压力偏差 三角洲 在一个实施例中，第一流体可以是天然气。

Abstract: A manifold for a pump is configured to connect to a jacket to form a reservoir and to connect to at least one pumping mechanism disposed within the reservoir. The manifold includes a first side including a first side surface configured to face the reservoir and a second side including a second side surface. The manifold also includes a bypass passage, at least one push rod guide bore extending through the first side surface and the second side surface, and a leakage passage fluidly connecting the at least one push rod guide bore to an outlet disposed outside the first side surface. The manifold further includes a discharge passage including at least one inlet disposed in the first side surface, and the at least one inlet is configured to receive fluid pumped by the at least one pumping mechanism.

Abstract: A barrel assembly for a pumping mechanism includes a first end, a second end opposite the first end, and a plunger bore configured to receive a plunger for sliding within the plunger bore. The barrel assembly also includes at least one inlet passage including at least one inlet extending through the first end and fluidly connected to the plunger bore to communicate fluid from the at least one inlet passage to the plunger bore. The barrel assembly further includes an outlet passage fluidly connected to the plunger bore and configured to receive fluid from the plunger bore, the plunger bore and the outlet passage forming separate openings in the second end of the barrel assembly.
