The DLLA158P1092 is a DENSO common rail injector nozzle widely used in Isuzu 4HK1 and 6HK1 diesel engines, as well as selected Case excavators, Dongfeng DCI11 trucks, and Hino commercial vehicles. Designed for DENSO injector families such as 095000-534# and 095000-636#, it delivers precise fuel atomization under injection pressures up to 2,000 bar.
Common symptoms of nozzle wear include:
✔ Black smoke under load ✔ Hard starting ✔ Rough idle ✔ Increased fuel consumption ✔ Excessive injector return flow
Before replacing a nozzle, always verify the injector assembly number and calibration code. Using an incorrect nozzle can lead to poor combustion, power loss, and premature engine damage.
If you're rebuilding DENSO injectors for Isuzu 4HK1 or 6HK1 engines, DLLA158P1092 remains one of the most commonly serviced nozzle models in the aftermarket.
