China's Precision Powertrain Components: Connecting Rods, Cylinder Heads, and Oil Pumps of Superior Quality

In an engine, the connecting rod, cylinder head, and oil pump are the three pillars of the powertrain, collectively ensuring efficient and stable combustion. Made in China, these core components utilize cutting-edge craftsmanship and stringent standards to deliver industry-leading reliability, providing long-lasting power to power equipment worldwide.

Connecting Rod

Forged from aviation-grade high-strength alloy, precision heat treatment and digital simulation optimization deliver a 15% weight reduction while exceeding 1100 MPa in tensile strength. A unique fracture-separation design ensures assembly accuracy within 0.003mm, while three-dimensional lubrication channels effectively reduce friction loss, ensuring smooth engine operation under high loads.

Cylinder Head

Integrating numerous innovative technologies, the high-pressure cast aluminum alloy with a nano-scale thermal barrier coating offers high-temperature resistance up to 480°C. The precision-machined intake and exhaust ports utilize CFD fluid dynamics optimization to increase the swirl ratio by 22%. Combined with multi-layer metal gaskets, these ensure zero combustion chamber leakage. Each finished product undergoes a 48-hour helium leak test to ensure long-term leak-free operation.

High-Pressure Fuel Pump

As the core of the fuel system, it utilizes the same technology platform as Bosch in Germany. The plunger assembly is treated with diamond-like carbon coating, achieving wear resistance three times the industry standard. The intelligent pressure regulation system responds to ECU commands in real time, precisely controlling oil pressure within a range of 180-300 bar, with a fluctuation of less than ±2 bar. Rigorous 2 million-cycle endurance testing demonstrates a performance degradation rate of less than 0.5% per 10,000 hours.

From raw material selection to laser inspection on the intelligent production line, each component undergoes 27 quality inspection processes in compliance with ISO/TS16949 international automotive industry standards. These precision components, embodying the wisdom of Chinese manufacturing, provide reliable, long-lasting power solutions for customers in passenger vehicles, construction machinery, and marine propulsion.
