294000-0516 Commonrail Injection Pump 22100-30070 for Toyota 1kd-Ftv2kd-Ftv Diesel Engine Oil Pump

This industrial-grade heavy-duty diesel engine high-pressure common rail fuel pump (OE part number: 294000-0516) is the precision control core of modern high-pressure common rail systems. It is widely compatible with Hino J05E, J08E, and other series of high-power diesel engines, and is perfectly suited for Hino heavy trucks, buses, and Kobelco SK200-8, SK210-8, SK250-8, SK260-8, SK350-8 and other mainstream medium and large tracked excavators. This product adopts an advanced electronically controlled metering valve (PCV/SCV) and a micron-level dual-plunger extrusion design, designed to continuously deliver ultra-high pressure and ultra-stable fuel rail pressure to the common rail pipeline and precision injectors. When your heavy-duty machinery or freight truck is equipped with this precision fuel pump, abnormal phenomena such as engine cold start lag, fluctuating idle speed, and rough operation caused by fuel pressure fluctuations will immediately disappear. During continuous high-load construction operations or heavy-load acceleration, you can intuitively feel the throttle response become extremely sensitive and linear, engine horsepower surges back, and the previously troublesome billowing black smoke is instantly cleared, restoring the full combat capability of the mechanical power system.

Direct Sales from Our Own Factory and Ample Stock:

Many cross-border buyers often encounter the harsh reality of excessively long cross-border procurement chains, layers of markups by agents, and indefinite shutdowns of machinery at construction sites due to parts shortages. Leveraging our strong, self-built modern manufacturing base, we have established a comprehensive, long-term, readily available warehouse for the 294000-0516 high-pressure oil pump. This fully closed-loop, first-hand supply chain model supports rapid packaging and lightning-fast delivery after order placement, not only saving overseas end-users significant procurement costs but also effectively ensuring your machinery can quickly return to the work site.

Digitalized Full Inspection Process and Nanoscale Anti-wear Pump Core:

Many low-end replacement parts on the market suffer from insufficient wear resistance and hardness of the pump body's moving parts. After a short period of operation, these components are prone to severe internal leakage due to trace impurities in the diesel fuel, leading to slow fuel pressure build-up when the engine is hot and stalling under high load. Therefore, every high-pressure fuel pump we manufacture undergoes rigorous multi-dimensional calibration under full-function digital common rail testing. The core plunger surface has been comprehensively upgraded with a DLC (diamond-like carbon) ultra-hard nano-coating, structurally sealing against leaks and pressure drops, exhibiting long-lasting performance under various harsh fuel environments.

Original Factory-Grade Dynamic Fuel Pressure Calibration and Superior Fuel Savings:

Addressing the objective reality of engine idling vibration, incomplete diesel combustion, and abnormally high fuel consumption caused by inaccurate fuel pump supply regulation, our products are manufactured strictly based on original OEM standards and electronic data. The high-precision SCV intake control valve executes ECU pressure adjustment commands with a microsecond-level response rate, ensuring that the fuel pumped into the common rail is always maintained within the ideal injection pressure range. This results in extremely uniform fuel atomization within the cylinder, effectively eliminating black smoke in the exhaust and significantly improving the thermal energy conversion rate of each drop of fuel, thus helping fleets substantially reduce fuel costs.

High-speed intercity high-slope fully loaded transportation by heavy-duty trucks:

On long-distance logistics arteries with undulating terrain and unpredictable weather, Hino heavy-duty trucks fully loaded with tens of tons of goods are challenging winding mountain slopes several kilometers long. The driver needs to press the accelerator pedal deeply to prevent the engine speed from dropping. The 294000-0516 high-pressure oil pump, based on instantaneous feedback from the electronic control unit, precisely adjusts the inlet valve to quickly establish and maintain a sufficient and stable high-pressure rail pressure. This ensures that the fuel mist sprayed by the injectors is fine and perfect, allowing the engine to generate amazing torque even at low speeds, helping the truck safely and smoothly pass over slopes and achieve timely logistics.

Continuous Earthwork Excavation at Construction Sites:

At urban infrastructure construction and road repair sites with extremely demanding schedules, multiple Kobelco SK200-8 crawler excavators are continuously crushing and heavy-load loading operations against hard layers of gravel. Due to the large-scale, high-frequency dynamic changes in frontal resistance, a slow response from the fuel system can easily cause the engine to stall. This high-pressure oil pump, with its excellent hydraulic and airtightness and vibration-resistant structure, can still provide precise and stable fuel supply even under prolonged full-power output and high-load vibration environments, helping the equipment move quickly and powerfully, ensuring the uninterrupted and steady progress of the project.
