0445120122 Common Rail Injector for Dongfeng Cummins ISLe Buses

0445120122 Dongfeng Cummins ISLe Injector Overview

The central identity for this product is 0445120122 with Cummins 4942359. It supports ISLe demand associated with Dongfeng vehicles and selected Yutong or King Long bus programs. Because 0445120121 sits beside it in many catalogs and stock systems, purchasing teams should place both the complete injector number and DLLA144P1707 on the order record.

The configuration uses nozzle 0433172045 / DLLA144P1707 and valve set F00RJ01941. These details are technical cross-checks for the complete solenoid common-rail injector. They are particularly helpful when a used injector label is damaged, but they do not replace chassis and engine validation or permit a nozzle component to be supplied against an assembly order.

Dongfeng DFL applications span tractor, tipper and rigid-truck arrangements, while bus fleets create different duty cycles and parts-control practices. Rather than publishing an unrestricted vehicle list, Elecdura asks the buyer to confirm the exact ISLe build, original injector and Cummins number. This keeps truck and bus procurement under one verified identity without merging every ISLe installation.

0445120122 One-Digit-Risk Supply Controls

For a Dongfeng request, include the DFL model or VIN, engine serial and 4942359. For a Yutong or King Long request, add the bus chassis and prior service record. If several vehicles are being consolidated, show quantities against each group. This lets the quotation preserve a common injector identity while exposing any unconfirmed vehicle subset before packing.

The agreed wholesale terms are 6–12 pcs minimum, 7–15 Days delivery, 12 months warranty and Neutral / Customized Packaging. Resale labels can lead with 0445120122 and add 4942359. Keep 0445120121 stock physically separated; an adjacent numeric label is not sufficient protection in a high-volume depot.

A qualified workshop should check cleanliness, seals and correction data before installation. The service procedure for the exact engine controls how individual injector information is entered or recorded. When a unit is rejected at receiving, document the body marking and carton label so the distributor can resolve the identity without opening other sealed units.

0445120122 Dongfeng Cummins ISLe Purchasing FAQ | B2B Buyer FAQ

What is the strongest cross-reference for 0445120122?

Cummins 4942359 is the principal OE cross-reference used with 0445120122. Include both numbers in the inquiry and compare them with the original injector. The nozzle and valve references add configuration confidence, while the vehicle VIN and engine serial determine whether the candidate belongs in the exact Dongfeng or bus application.

Why is the nozzle number important on this product?

DLLA144P1707 and 0433172045 distinguish the 0445120122 configuration from neighboring injectors, especially 0445120121. They help technical staff catch a one-digit picking error. The nozzle reference remains a supporting identifier; a complete injector purchase cannot be approved from a nozzle number without the assembly and engine checks.

Can one order combine Dongfeng trucks and buses?

It can if every subgroup has been verified for 0445120122 and 4942359. List quantities by truck or bus fleet and provide chassis and engine information for each. Consolidating freight should not erase the application boundary. Any uncertain vehicle group should remain outside the released quantity until its original injector is confirmed.

How should 0445120121 stock be separated from 0445120122?

Use bin labels that show the full ten-digit injector number and the distinct nozzle code, and require a second scan or visual check during picking. Do not shorten labels to 121 or 122. Receiving and dispatch teams should compare 4940640 versus 4942359 as an additional control before sealing customer cartons.

What should be checked on a removed injector?

Record the complete body number, connector orientation, inlet position and any legible Cummins reference. Photograph the label before cleaning if possible. Compare the nozzle-end profile only as supporting records. The service team should also note engine serial and controller information needed for correction-data handling after the replacement arrives.

Does a King Long or Yutong name guarantee fitment?

No. Those manufacturers use multiple engine and emissions configurations across model years. The application is a valid sourcing direction, but the bus chassis, Cummins ISLe build and original injector must agree. Distributors should avoid broad web-store claims that convert a supported fleet family into unconditional compatibility for every bus.

What is a useful carton label for resale?

A practical label leads with 0445120122, adds Cummins 4942359 and states the customer's approved application group. If customized packaging is requested, preserve traceability to the physical unit and correction information. Avoid placing generic ISLe wording more prominently than the actual injector number because it encourages substitution at the counter.

What data should be included when requesting 12 pieces?

Send the exact injector and Cummins numbers, vehicle groups, engine serial ranges if available, destination, packaging choice and requested ship date. State whether all 12 pieces are for one verified fleet or several applications. That distinction helps plan labels and receiving documentation while keeping the 7–15 day target realistic.
