Dongfeng KInland truck spare parts Imported nitrogen oxide sensors A066V795

As a critical component for monitoring and controlling vehicle emissions, this imported NOₓ sensor adopts advanced zirconia ceramic sensing technology for ultra-accurate detection. It measures NOₓ concentrations in the exhaust gas with a range of 0-2000 ppm and a measurement error of ≤2%, providing real-time data to the ECU for precise urea injection control. The sensor’s integrated heater (120W) enables rapid light-off (≤30 seconds) even at low exhaust temperatures (≥150℃), ensuring reliable detection from cold starts. For Dongfeng Kinland trucks operating in urban logistics, this precision ensures the SCR system maintains NOₓ emissions below 0.08 g/kWh, avoiding fines for non-compliance with environmental regulations

Engineered to endure the extreme conditions of truck exhaust systems, the A066V795 sensor features a rugged imported construction. The sensing element is made of high-purity zirconia ceramic (99.9% purity) with a porous platinum electrode, resisting corrosion from exhaust acids and thermal shock (temperature cycles from -40℃ to 850℃). The housing is crafted from heat-resistant Inconel alloy (Ni-Cr-Mo) with a melting point of 1450℃, maintaining structural integrity under continuous exhaust temperatures up to 650℃ (short-term tolerance of 850℃). A double-layer stainless steel protection tube (316L grade) prevents damage from exhaust particulates and road debris, while the internal wiring uses high-temperature silica insulation to avoid short circuits

Optimized for global operating environments, the imported NOₓ sensor exhibits exceptional adaptability to temperature, humidity, and fuel quality. It operates stably within a ambient temperature range of -40℃ to 125℃, adapting to frigid northern winters and high-temperature desert operations. The IP6K9K protection rating (per IEC 60529) ensures complete dustproof performance and resistance to high-pressure, high-temperature water jets—ideal for trucks exposed to rain, snow, and off-road mud. The sensor’s anti-poisoning design resists contamination from sulfur and heavy metals in low-quality diesel, maintaining accurate detection even with fuel sulfur content up to 500 ppm (common in remote regions). Its CAN FD communication ensures stable data transmission even in high-electromagnetic-interference environments (e.g., near truck inverters)

The A066V795 NOₓ sensor plays a pivotal role in optimizing emission performance and reducing long-term operational costs. By providing accurate NOₓ data, it enables the ECU to adjust urea injection quantity dynamically, reducing urea consumption by 8-10% compared to faulty sensors. This not only lowers urea costs but also prevents urea crystallization in the SCR system (repair costs up to $1,500). The sensor’s early warning function alerts the driver to abnormal NOₓ levels, avoiding engine derating (which reduces power by 50%) and unplanned downtime (costing $1,000+ per hour for long-haul fleets). As an imported OE-grade part, it offers a service life of ≥300,000km—twice that of aftermarket sensors—reducing replacement frequency. Backed by a 2-year/250,000km warranty, it ensures compliance and reliable performance for Dongfeng Kinland operators
