Part Number: CUMMINS‑134N
Type: Mechanical fuel injector (not electronic, not common rail)
Fuel Type: Diesel
Manufacturer: Cummins (OEM specification, often supplied via Bosch or Delphi depending on engine family)
Engine Applications:
Cummins N‑series and K‑series mechanical diesel engines
Heavy‑duty trucks, buses, and industrial machinery using mechanical fuel systems
Function:
Receives pressurized fuel directly from the mechanical injection pump
Atomizes fuel into the combustion chamber at the correct timing
Maintains consistent spray pattern for efficient combustion
The CUMMINS‑134N is a mechanical diesel injector designed for Cummins engines. Unlike modern common rail (CR) injectors, this is a traditional mechanical unit used in older Cummins heavy‑duty applications where fuel delivery is controlled by the injection pump rather than electronic solenoids.
