Product Details
Component 612700090016 operates as a fully integrated solenoid-type common-rail injector cartridge configured for Weichai WP7/WP6 medium-duty and selected WP5/NG variant platforms. It consolidates the electromagnetic actuator, pilot valve group, needle-seat assembly, and multi-orifice DLLA-class tip into one sealed unit that seats into the cylinder head via M12×1.5 thread with copper washer. Rated for 1400–1600 bar rail pressure (CPL-dependent), it upholds invariant pilot-shot consistency and main-event penetration symmetry across −25 °C cold crank and +110 °C thermal saturation. Body nitrided alloy steel, laser-welded coil housing; cross-reference: Weichai 612700090016 / Bosch 0445120xxx-class exchange.

Our Advantages
Restructured internal flow geometries deliver expedited fuel pressure feedback, sustaining dependable torque generation over an extensive engine speed spectrum and curbing fuel consumption at idle and steady highway cruising conditions. Each finished assembly is subjected to standalone functional validation on certified test rigs to audit opening pressure, sealing robustness and spray consistency, ensuring homogeneous operational performance throughout all production batches. Engineered as a direct interchangeable component compliant with OEM fitment criteria, it eliminates the need for field adjustments during maintenance and slashes equipment downtime significantly. Its rugged structural build facilitates prolonged service life aboard heavy-duty haulage vehicles and stationary diesel power assemblies. Ample stocked inventory caters to small pilot orders and large export shipments, accompanied by tailored logistics packages and ongoing professional technical consultation via authorized regional business associates.
FAQ
1.Tip or whole injector?
Whole injector. Solenoid, valve, tip, HP connector in one body. No separate DLLA tip or KDAL holder to buy.
2.WP7 unit into WP6 without changes?
Threads match, drops in mechanically. But flow-code/IMA trim differs by CPL-fit without ECU trim update → cylinder lambda spread, P020x fault. Match CPL code, not just fit.
