Sinotruk Howo fuel pump assembly, model VG1500080100, is a core component of the fuel supply system for heavy-duty truck diesel engines.

I. Core Product Identifiers

Model Specifications: VG1500080100 (Fuel Pump Assembly)

Product Positioning: Core power component of the fuel supply system for heavy-duty truck diesel engines, specially designed for Sinotruk Howo series models. It is a key component ensuring engine fuel transmission efficiency and operational stability. It has passed authoritative certifications such as ISO/TS 16949 and ISO 9001, and its original factory-fit quality is guaranteed.

II. Core Functions and System Value

As a fuel supply system..." The "power hub," this fuel pump assembly, undertakes three key missions:

Efficient fuel delivery: Precisely draws diesel fuel from the tank, overcomes pipeline resistance, and delivers it to the high-pressure fuel pump, providing a continuous and stable fuel supply to the WD615 series engine, meeting the fuel demands of heavy-duty trucks operating under heavy loads and for extended periods;

Precise pressure control: The output pressure is stabilized at 1.8-2.5 kg/cm² (compliant with JB/T 6291.1-200).4 Industry Standards) ensure that fuel enters the high-pressure fuel pump in optimal condition, providing a foundation for subsequent atomization injection and improving combustion efficiency;

System protection empowerment: In conjunction with the fuel filter, it achieves preliminary filtration of impurities, reduces wear on precision components such as the high-pressure fuel pump and injectors, and at the same time, through the hand pump venting function, it avoids starting failures caused by fuel circuit air resistance and extends the service life of the whole machine.

III. Structural Design and Performance Advantages

1. Cast Iron Pump Body: The Reliability Cornerstone for Heavy-Duty Scenarios

It adopts high-strength cast iron material in one piece, which, compared with aluminum alloy material, shows three core advantages under the high-frequency vibration and complex working conditions of heavy trucks:

Excellent mechanical strength: tensile strength reaches 450MPa The above features allow it to withstand severe impacts and pressure fluctuations during heavy-duty driving without the risk of deformation or cracking; Strong environmental adaptability: naturally resistant to moisture and salt spray corrosion, requiring no additional rust prevention treatment, suitable for harsh operating environments such as mines and infrastructure projects; Outstanding thermal stability: superior high-temperature resistance compared to aluminum alloys, maintaining structural stability in the high-temperature environment of the engine compartment, avoiding the impact of thermal expansion and contraction on sealing performance. 2. Piston pump core: the core technology for stable oil supply.The built-in precision piston pump core, using a camshaft drive design (synchronously operating with the camshaft of the WD615 series engine fuel injection pump), achieves three major technological breakthroughs:

Fuel supply stability: Driven by the eccentric wheel of the camshaft, the piston reciprocates, ensuring fuel supply pressure fluctuation ≤ ±0.02MPa, guaranteeing uniform fuel distribution in multi-cylinder engines;

Adaptive flow regulation: When the fuel supply exceeds the fuel injection pump's requirements, the piston stroke is automatically adjusted through oil pressure feedback to avoid fuel waste and adapt to different engine load conditions;

Long life design: The piston and pump sleeve are ultra-precision machined, with the clearance controlled at 0.003-0.005mm, exhibiting excellent wear resistance and a cumulative working life of over 8000 hours.

3. Integrated hand pump: A practical configuration for convenient maintenance.

Equipped with a design conforming to JB/T 6291.1-2004 The standard high-efficiency hand pump can complete the oil pumping operation after bleeding the oil circuit or replacing the filter within 45 presses, improving maintenance efficiency compared to traditional designs:

Emergency start guarantee: After the vehicle has been parked for a long time, or after replacing the filter or adding air to the oil circuit, the manual pump can quickly build up oil pressure, solving the problem of difficult cold starts;

Ease of operation: The hand pump handle is ergonomically designed.Comfortable to hold, moderate pump resistance, operation can be completed without professional tools;

Sealing reliability: The hand pump has a built-in high-quality sealing ring, and the sealing pressure is maintained at ≥0.4MPa within 10 seconds, with no risk of leakage.
