294000-0744 22100-E0051 Fuel Injection Pump Common Rail Injection Pump for Hino Engine

This high-performance diesel engine high-pressure fuel pump (OE No.: 294000-0744) is designed for heavy-duty and high-intensity operating environments. As the core of the diesel common rail system, it is precisely matched to mainstream diesel engines such as the Isuzu 4HK1 and 6HK1, and is widely used in Hitachi, construction machinery, and heavy-duty trucks. Adhering to the design philosophy of "precise pressure control and efficient atomization," the product significantly improves fuel economy and reduces emissions through ultra-high-pressure fuel injection technology. When you start the vehicle, you can clearly feel the smooth and powerful engine output, quieter and smoother idling, and it provides a continuous and lag-free power response even under extreme loads, making it a reliable choice for ensuring efficient equipment operation.

• Direct supply from the source factory, solving the problems of high procurement costs and long waiting times, bringing customers ultimate cost-effectiveness and supply chain security. As an integrated factory with independent R&D and manufacturing, we have ample stock. Not only do we break the price monopoly of major overseas brands, significantly reducing your procurement and time costs, but we also promise rapid delivery after ordering, helping your equipment or customer vehicles return to operation in the shortest possible time for seamless operation.
• 100% rigorous factory quality inspection eliminates the hidden dangers of inconsistent quality in modified and refurbished parts in the industry, bringing customers original factory-level safety and long-term stability. Every high-pressure oil pump must pass industry-leading automated high-pressure performance testing before leaving the factory, undergoing multiple process checks including pressure fluctuation, sealing, and flow accuracy. This ensures that what you receive is a zero-defect, high-specification work of art, completely eliminating the risk of secondary repairs such as oil leaks and stalling.
• High-wear-resistant alloy materials and precision manufacturing processes solve the problem of premature wear of components caused by inferior diesel fuel, bringing customers an exceptionally long equipment lifespan. For complex and variable fuel quality, we have applied a special hardened surface treatment to the internal plungers and control valves. Its anti-friction and corrosion resistance far exceeds that of ordinary products of the same type, effectively resisting wear from microparticles, significantly extending the pump's working life, and significantly reducing the long-term maintenance costs of the entire vehicle.

• Construction Sites and Mining Operations: In harsh outdoor construction sites, Hitachi excavators face prolonged periods of high-intensity, heavy-load excavation and material handling. Frequent throttle inputs by operators place extremely high demands on the fuel system's instantaneous pressure. This high-pressure fuel pump continuously provides stable and precise ultra-high-pressure fuel, ensuring the engine maintains its speed and doesn't stall under continuous high loads, guaranteeing efficient project progress.
• Long-Distance Cross-Border Logistics Trucks: Long-haul freight trucks traverse different regions, encountering varying fuel quality along the way, and often need to travel continuously for several days. Drivers' biggest concern is breaking down on the road. After installing this fuel pump, its superior wear-resistant structure and filtration adaptability become apparent, resulting in thorough fuel atomization and excellent fuel economy during long-distance travel, providing truck drivers with a smoother driving experience.
• Equipment Repair Shops and Parts Traders: When customers bring in vehicles with insufficient power or emitting black smoke for repair, automotive and construction machinery repair shops require a high-quality, precisely matched replacement part. This oil pump is fully compliant with original factory specifications. The holes fit perfectly during installation, allowing for immediate use. This has not only earned praise from repair technicians but also resulted in a high repurchase rate for trading companies.
