294000-0196 294000-0199 Diesel Fuel Injection Pump Injection Oil Pump 22100-E0280 22100-E0283 for Hino/Toyota N04c-Tq Truck

This industrial-grade heavy-duty diesel engine electronically controlled common rail injector (OE No.: 295050-0411) is a high-precision core actuator in modern high-pressure common rail fuel supply systems. It is widely compatible with many mainstream medium and heavy-duty commercial vehicles, modern excavators, and special-purpose diesel engines. This product integrates cutting-edge electro-hydraulic servo control valve design and micron-level multi-hole nozzle manufacturing technology, designed to handle high-intensity, variable-load continuous construction operations. After installing this precision common rail injector, you will intuitively experience a complete transformation of your power system: engine cold starts are instantaneous; the sluggish idling speed, abnormal vehicle vibration, and metallic knocking sounds previously caused by poor atomization or pressure leakage instantly subside, replaced by a crisp, highly regular, and stable engine roar. Under extreme heavy loads or steep inclines, every deep press of the accelerator delivers a linear surge of horsepower without lag; the billowing carbon soot and black smoke that previously plagued the exhaust system completely disappear, restoring your core equipment to peak performance like a brand-new machine.

• Direct Sales from Our Own Modern Factory and Ample Stock: Many overseas buyers are often hampered by long foreign trade chains, multiple layers of intermediaries profiting from price differences, and even suffer from shortages of core components, forcing expensive machinery to remain idle on construction sites for extended periods, resulting in significant daily losses. Leveraging our technologically advanced self-built manufacturing base, we maintain a large, regular inventory of our popular 295050-0411 model. This direct-from-the-end factory model allows for rapid packaging and shipment after order placement, eliminating all intermediary profit margins and ensuring your equipment can return to operational status in the shortest possible time.
• Full-Process Digitalized Strict Quality Inspection and DLC Ultra-Hard Anti-Wear Valve Needle: Some low-end replacement parts on the market, due to insufficient anti-wear hardness of the sealing surface, are prone to wear from minute impurities in diesel fuel after short-term operation, leading to internal pressure loss, failure to build up oil pressure when hot, and engine stalling under high load. Therefore, every injector we manufacture undergoes rigorous testing on a full-function digital common rail test bench, testing its flow regulation, pressure sealing, and dynamic return flow under various operating conditions. The core control valve needle and moving parts have been upgraded with a DLC (diamond-like carbon) ultra-hard nano-coating process, structurally sealing off potential wear hazards and ensuring excellent long-term durability even under harsh high-temperature and high-pressure fuel environments.
• Precision Multi-hole Geometric Calibration and Superior Fuel Efficiency: Addressing the issue of sluggish engine power, excessively high cylinder temperatures, and abnormally high fuel consumption caused by nozzle flow deviations from the original factory calibration, our products are meticulously manufactured based on original OEM data standards and electronic parameters. The precise multi-hole nozzle geometry ensures fine and uniform diesel particles under ultra-high rail pressure, achieving a more perfect mixture and combustion with the air in the cylinder. This not only completely eliminates the persistent problem of black smoke in the exhaust during mechanical operation but also significantly improves fuel conversion efficiency, helping owners save substantial hourly fuel costs during long-term operation.

• Continuous Earthwork Excavation at Large-Scale Infrastructure Construction Sites: At construction sites with extremely demanding schedules, heavy-duty tracked excavators are continuously crushing and loading heavy loads onto layers of hard gravel. Because the frontal resistance is constantly undergoing large-scale, high-frequency dynamic changes, a slow-responding fuel system can easily cause the machine to stall. The 295050-0411 fuel injector, with its extremely high hydraulic servo airtightness and rapid response capability, can still provide precise and stable fuel supply even under prolonged high-load vibration environments at full power output, assisting the equipment in rapid and powerful movements and ensuring the uninterrupted and steady progress of the project.
• Heavy-Duty Commercial Vehicle Highway Logistics Long-Distance Transport: On the intercity highway logistics arteries with undulating terrain and huge temperature differences, commercial heavy trucks fully loaded with tens of tons of cargo are challenging winding mountain slopes several kilometers long. Drivers need to frequently press the accelerator pedal deeply to prevent the engine speed from dropping. This injector receives the ECU pulse signal and reacts in microseconds, delivering extremely even fuel mist into the cylinder under ultra-high rail pressure. This ensures that the engine can generate amazing thrust even at low speeds, easily passing through high-load and dangerous road sections, helping the vehicle smoothly and successfully overcome slopes and achieve timely logistics deliveries.

• Q: How can I confirm that this injector is perfectly matched to my diesel engine?
  A: The matching requirements for components in a high-pressure common rail system are very strict. The most direct method is to check if the side of the old injector housing you replaced from your original vehicle has a laser-marked or stamped code containing "295050-0411". If you are still unsure, you can send a photo of your engine serial number or vehicle nameplate to our customer service staff, and we will conduct a free, accurate technical verification using big data.
• Q: If I purchase this high-pressure injector from your independent website, do I need to send back the old, defective part (Core Charge)?
  A: Absolutely not. We operate on a pure factory-direct, net-price model. The injector you order is a brand-new, upgraded, high-quality product. You don't need to go through the hassle of sending back the old core component, saving you expensive international shipping costs and transit time, making your parts procurement simpler and more transparent.
• Q: How long is the warranty period after purchase? What should I do if a malfunction occurs during the warranty period?
  A: We provide an official quality guarantee of up to 12 months (one year) from the date of receipt. During the warranty period, if the product operates in a clean and qualified diesel fuel environment but experiences any non-human-caused malfunction due to its own manufacturing quality, simply contact our after-sales team and provide a simple inspection description. We will provide you with free replacement parts or replacement compensation services as soon as possible.
• Q: What technical installation advice do you have for our mechanics when installing this brand new high-pressure common rail injector?
  A: Modern high-pressure common rail systems are extremely precise high-pressure hydraulic networks, and are highly susceptible to contamination from micron-sized dust particles or trace amounts of moisture in the fuel. Before installing the new injector, please ensure that your technicians thoroughly empty and clean the original vehicle's diesel fuel tank and low-pressure fuel lines, and replace the fuel filter with a brand new, high-specification one. Installation in an environment ensuring 100% absolute purification of the fuel system will significantly extend the lifespan of the new fuel pump. Also, please remember to have the corrected code flashed into the ECU under the guidance of a professional technician.
• Q: What is your current stock situation? Approximately how many days does it take for goods to arrive in our country after an order is placed overseas?
  A: As a factory-direct sales outlet, we maintain a large and ample stock of this injector model in our central finished goods warehouse year-round. Within 24 to 48 hours of your payment, the goods will undergo multi-layered vacuum rust-proof and shock-proof packaging and be delivered to leading international express delivery companies such as DHL, FedEx, and UPS. Under normal circumstances, customers in major regions such as Europe, America, the Middle East, and Southeast Asia can successfully sign for their packages within 5-7 business days.
