Construction and power generation equipment operators know how costly downtime is — a single day of engine failure can cost thousands in lost productivity and emergency labor. Many have installed counterfeit or mismatched fuel injectors only to face uneven combustion, excessive smoke, and repeated injector failures within weeks. OEM parts often require 2–4 weeks lead time, delaying critical maintenance during peak project windows.
This fuel injector ED0050101680-S is manufactured in ISO-certified factories under strict process control and tested for spray pattern, opening pressure, and leakage before shipment. With 10 years’ experience supplying Kohler diesel engine components globally, XUNPO ensures consistent performance across all units — whether you’re servicing a portable generator or a heavy-duty industrial power unit. All units are new aftermarket replacements built to match original flow rate and atomization specifications.
This injector is deployed in demanding environments: construction site generators, rental fleet power units, municipal utility vehicles, and marine auxiliary engines — where continuous operation under variable load and ambient temperature requires precise fuel delivery. In high-hour applications like quarry compressors or remote telecom shelters, incorrect injector calibration leads directly to carbon buildup, reduced efficiency, and premature cylinder head damage. The ED0050101680-S is engineered for stable performance at 180–220 bar injection pressure and rated for 12,000+ operating hours under proper oil maintenance.
The nozzle tip is precision-ground from hardened stainless steel (HRC 58–62), ensuring resistance to cavitation erosion and thermal fatigue over extended duty cycles. Internal needle valve geometry matches OEM tolerances within ±2 µm, maintaining consistent lift timing and preventing pre-ignition knock. Sealing surfaces use Viton® O-rings rated to 200°C, eliminating hot-start leaks common in low-grade alternatives. Each unit undergoes hydraulic pressure testing at 250 bar for 60 seconds with zero leakage — exceeding ISO 8536-4 requirements for diesel injectors.
A $45 counterfeit injector may save upfront, but it often fails within 500 operating hours — triggering secondary damage to glow plugs, ECU sensors, and even the high-pressure fuel pump. Replacing one failed injector mid-cycle rarely resolves imbalance; mixing genuine and aftermarket units causes uneven cylinder loading, accelerating crankshaft wear and increasing NOx emissions beyond regulatory limits. Total cost of ownership (TCO) favors certified aftermarket parts: XUNPO’s ED0050101680-S delivers 98% of OEM service life at 40% lower acquisition cost — backed by documented test reports and real-world field data from 120+ countries.
— We source exclusively from ISO 9001-certified factories, with incoming material inspection on every batch.
— Every fuel injector undergoes full functional testing: opening pressure verification, spray angle measurement, and dynamic response check.
— 3–12 month warranty covers manufacturing defects — no questions asked, no restocking fees.
— 10 years of export experience serving customers in North America, Europe, Southeast Asia, Africa, and South America.
— Our technical team includes 8 certified diesel engine specialists; part compatibility confirmation is delivered within 2 hours.
— Over 10,000 SKUs held in our Guangzhou warehouse — ED0050101680-S ships within 2–5 working days.
Your excavator or generator isn’t generating revenue while it’s down — every hour of delay adds cost. Send us your part number (ED0050101680-S or 123645789), machine model (KDI1903TCR/KDI2504TCR), and required quantity. We’ll reply with a competitive quote within 24 hours. First-time buyers can request a sample for bench testing before placing a full order.
Q: Is this an original Kohler part or an aftermarket replacement?
A: This is an OEM-equivalent aftermarket fuel injector, manufactured in ISO 9001-certified facilities to match original performance, fit, and durability.
Q: How do I confirm this fits my specific engine?
A: Provide your engine model (e.g., KDI1903TCR) and serial prefix — our technical team verifies compatibility and replies within 2 hours.
Q: What is the warranty period?
A: 3–12 months from date of shipment, covering defects in materials and workmanship — no registration required.
Q: What is the minimum order quantity?
A: 1 piece — we support urgent maintenance needs and small-scale testing.
Q: How long does shipping take?
A: In-stock items ship within 2–5 working days. Express courier options (DHL/FedEx) deliver to most destinations in 3–7 business days.
Q: Can I receive a sample for testing before ordering in bulk?
A: Yes — first-time customers may request one sample injector ED0050101680-S for evaluation under standard terms.
