Think of the barrel and plunger as a super-precise, high-pressure syringe. They are the core components of the fuel injection pump, often within a larger assembly like the Cummins PT pump or the rotary distributor pump. The Barrel: This is the stationary, hardened steel sleeve with a perfectly honed inner bore. The Plunger: This is the piston that fits with microscopic clearance inside the barrel. Their job is a two-step process: Fuel Intake: As the plunger moves down, it uncovers a port in the barrel, allowing low-pressure fuel to fill the chamber. Pressurization & Injection: As the plunger moves up, it first closes the port and then compresses the trapped fuel to extremely high pressures (often thousands of PSI). This pressurized fuel is then forced through the injector and atomized into the combustion chamber. Without this precise action, you wouldn't get the fine mist of fuel required for a powerful and efficient explosion inside the cylinder. www.cq-longshine.com/cummi
