Cummins NH220, NH250, NT855 Engines
For combustion to occur at the right point in the cycle, the Cummins Fuel Injector meters fuel and sends it into the engine during operation. Its timed delivery allows fuel to enter the combustion area as the engine runs through acceleration, load changes, and steady-speed driving. This repeated metering action supports ongoing engine function by keeping fuel moving into the process when needed. In heavy-duty service, the injector works continuously as part of the fuel system so the engine can keep operating across long routes and demanding use. Each cycle depends on accurate fuel entry into the combustion event. Late in that sequence, the Cummins 3070178PX continues the fuel delivery process for running operation.
