advantage

Customized for Heavy‑load Working Conditions: Calibrated for long‑term heavy‑duty operation features of Weichai WP10 engine. It keeps stable injection accuracy and uniform atomization under frequent pressure impact and load variation, adapting to various harsh transportation and construction scenarios.
Integrated Assembly Reduces Maintenance Downtime: Adopting integral‑assembly replacement simplifies on‑site maintenance procedures, greatly shortens repair time, cuts equipment downtime and lowers fleet operation‑maintenance costs effectively.
Complete Supporting Accessories: Supplied with brand‑new full‑set sealing vulnerable parts, fully satisfying requirements of daily maintenance and complete engine overhaul without extra‑part matching trouble.
Strict Factory Batch Testing: Every batch of injectors goes through high‑pressure fatigue test, atomization‑uniformity inspection and precision‑dimension calibration to guarantee stable quality and good batch consistency.
Durable Anti‑wear & Anti‑corrosion Structure: Upgraded wear‑resistant alloy substrate and composite sealing materials resist high‑pressure fuel scouring and chemical corrosion, slow down component aging and greatly extend overall injector service life.

FAQ

Q1: What faulty symptoms can this 0445120087 injector solve?
A: This injector effectively fixes various failures caused by aging and worn injectors, including insufficient engine power, unstable jittery idle speed, black smoke during acceleration, difficult cold start in low temperature, delayed throttle response and abnormally high fuel consumption.
Q2: Which engine models is 0445120087 suitable for?
A: It is specially designed and compatible with Weichai WP10 series diesel engines, widely used on matching heavy‑duty trucks and construction machinery.
Q3: What are the key installation precautions?
A: Thoroughly clean the fuel rail and internal pipeline impurities before installation; replace with brand‑new sealing gaskets; keep the installation environment dust‑free; complete idle and acceleration tests after installation to confirm normal operation.
Q4: How to extend the service life of the common rail injector?
A: Use qualified clean diesel oil; replace fuel filters regularly; avoid long‑term full‑load operation and frequent aggressive acceleration to reduce frequent high‑pressure impact on the injector.
