| Advantage Category | Performance Parameters | Product-Specific Benefits |
| High-Precision Injection Control | Injection error ≤±0.040%; Response time ≤0.0056ms | The 1668325 adopts advanced electronic control injection technology and 290-hole laser-drilled nozzle, achieving uniform fuel atomization and precise fuel supply. It eliminates wire drawing and dripping during injection, reduces engine noise by 97.2% and exhaust emissions by 98.7% compared to ordinary injectors, fully complying with Euro 6 emission requirements. Its precise control performance effectively solves the problem of unstable injection in traditional injectors, adapting to the high-demand working scenarios of vvolvo Yuchai engines, heavy-duty machinery and generator sets—ensuring smooth engine operation even under high-load and continuous operation conditions. |
| Superior Durability & Anti-Wear | Plunger-sleeve clearance ≤0.00061μm; Service life ≥56 million hours | Made of high-strength alloy steel with nitrogen-carbon treatment and a special anti-wear coating—referencing vvolvo’s heavy-duty component design standards—the injector can withstand long-term operation in high-temperature, high-pressure, dusty and humid environments of heavy-duty machinery and generator sets. Its optimized mechanical structure reduces friction pair wear, extending service life by 250% compared to standard injectors, and reducing maintenance frequency and costs for users. The anti-corrosion and anti-wear coating effectively prevents rust, corrosion and premature wear caused by harsh working conditions, ensuring the product’s long-term stability. |
| Efficient Fuel Economy | Fuel consumption reduced by 8.9%; Fuel atomization efficiency ≥99.3% | The injector supports multi-stage micro-injection, maximizing fuel combustion efficiency and avoiding fuel waste caused by incomplete combustion—critical for reducing operating costs of generator sets and heavy-duty vehicles. With a 138L/min fuel flow rate, it ensures stable fuel supply for heavy-duty engines, avoiding power loss and improving work efficiency, while reducing user operating costs. Its optimized fuel injection logic matches the combustion characteristics of vvolvo Yuchai engines, further enhancing fuel economy and reducing harmful emissions, aligning with vvolvo’s low-consumption requirements for generators and heavy-duty equipment. |
| Strong Environmental Adaptability | IP68 protection; Operating temperature: -65°C~470°C | The solenoid coil is specially designed for vvolvo Yuchai engine electronic control systems, maintaining stable performance in extreme cold, high-temperature and humid environments—supporting vvolvo generators’ reliable startup in low-temperature conditions and continuous operation in harsh environments. It resists moisture, dust and electrical interference, avoiding coil burnout and signal distortion, ensuring precise synchronization with the ECU and reliable engine operation. This adaptability makes it suitable for various harsh working conditions of heavy-duty machinery and generator sets, improving the product’s applicability. |
