Bus Yuchai Engine Doctor 2.2 Metering Injection Unit 0444042136/K1000-120340-A38-1
Product Description
Ensure Emissions Compliance and Optimal Engine Performance.
The efficiency and environmental compliance of your modern bus fleet depend on a perfectly functioning SCR (Selective Catalytic Reduction) system. The Bosch 2.2 Dosing Injection Unit is the heart of this system, and Nanjing Dingguan Accessories Co., Ltd. manufactures this high-precision replacement to keep your fleet running clean, compliant, and strong.
This vital component is responsible for accurately injecting the precise amount of AdBlue®/DEF (Diesel Exhaust Fluid) into the exhaust stream. This process neutralizes harmful NOx emissions, allowing your Yuchai-powered buses to meet stringent environmental standards. A faulty unit can lead to engine warning lights, reduced power (“limp mode”), and failed emissions tests, resulting in fines and vehicle downtime.
Key Features:
- Precision Injection: Delivers the exact required amount of AdBlue®/DEF for maximum NOx reduction and efficient fluid consumption.
- Direct OEM-Standard Replacement: Engineered to the exact specifications of Bosch P/N 0444042136 and Yuchai P/N K1000-120340-A38-1 for a perfect, hassle-free installation.
- Critical for Emissions Compliance: Ensures the SCR system operates effectively, keeping your fleet compliant with modern environmental regulations.
- Robust and Reliable: Constructed with high-grade, chemical-resistant materials to withstand the harsh conditions of the exhaust system and ensure a long service life.
As a direct manufacturer, Nanjing Dingguan Accessories Co., Ltd. provides this critical component with rigorous quality control and competitive pricing.
