In-line plunger fuel injection pump is a critical fuel supply device for diesel engines. Its primary function is to precisely control and measure the fuel injection quantity and timing based on varying engine operating conditions. This type of fuel injection pump is named after its structural characteristics and working principle. The following sections will provide a detailed introduction to several key aspects of this device. Structural Characteristics: 1. Plunger Design: The core components of the In-line pump for engine consist of one or more plunger pumps, each corresponding to an individual cylinder. The plunger reciprocates within the pump chamber, altering its volume to achieve fuel suction and compression. 2. Inline Arrangement: All plunger pumps are mounted on a common shaft, forming a linear layout, which gives rise to the term "in-line" pump. 3. Governor: To accommodate changes in engine speed, inline fuel pump for diesel typically includes a governor that automatically adj…
