Diesel Nozzle DLLA142S1189

The DLLA142S1189 Diesel Injector Nozzle is a precision multi-hole nozzle designed for compatible mechanical diesel fuel injection systems. It is used to control fuel metering, spray formation, and atomization at the injector tip, making it suitable for injector servicing and replacement.

Key Features
Nozzle Model: DLLA142S1189
Nozzle Type: Multi-hole diesel injector nozzle
Fuel System: Mechanical Diesel Injection
Application: Injector repair, overhaul and nozzle replacement
Function: Fuel metering, spray formation and atomization
Application & Compatibility

DLLA142S1189 is intended for compatible diesel injector assemblies where the original nozzle uses the same DLLA142S1189 specification. It can be used in diesel engine injector rebuilding, maintenance, and replacement applications.

For accurate fitment, compare the original nozzle number, injector/holder assembly, injection pump specification, and engine model before ordering. Nozzles with similar dimensions or spray angles are not necessarily interchangeable because internal flow and spray characteristics can differ.

Replacement & Service

A worn or contaminated injector nozzle may contribute to poor fuel atomization, hard starting, rough engine operation, excessive exhaust smoke, reduced power, or increased fuel consumption. Replacing the nozzle can help restore the injector’s intended spray characteristics when the injector body and other components remain serviceable.

After installation, the injector should be cleaned, pressure-tested and calibrated according to the specifications of the complete injector assembly.
