Connecting Rod Assy1004100F0000 – Engineered for Strength, Performance, and Precision
Our connecting rod1004100F0000 assembly’s a total workhorse when it comes to engine parts—it links the piston up to the crankshaft, turning that back-and-forth linear motion into the rotational power the engine needs. We make it with super precise craftsmanship, and it’s built tough to handle those high-pressure, high-heat conditions inside an engine. That way, your engine stays running at its best, and you can really count on it.
Here’s what makes it stand out:
Strong-as-nails materials: We forge it from top-notch alloy steel or high-quality forged iron—so it’s seriously strong, and it can handle wear and tear without giving out.
Super precise machining: It’s CNC-machined to super tight tolerances. That means everything lines up perfectly, stays balanced, and your engine runs nice and smooth.
Heat-treated for long life: We also put it through advanced heat-treating. This boosts its hardness and makes it last way longer than cheaper alternatives.
Fits OEM standards (or better): It’s designed to meet even OEM specs—or even beat ’em. Whether it’s how it fits, how it works, or how durable it is, it checks all the boxes.
Balanced for steady performance: Every single rod gets weight-balanced too. That keeps your engine performing steadily, and cuts down on annoying vibration.
Core process advantages
Integral die forging forming: The blank is formed in one go by a 6300-ton hot die forging press. Metal fibers are distributed along the contour of the rod body, and the fatigue strength is 60% higher than that of the casting.
CNC precision machining: The large and small head holes are processed by the German EX-CELL-O precision boring machine, with a parallelism error of ≤0.03mm/100mm, ensuring the concentricity of the piston and crankshaft moement.
Surface strengthening treatment: The rod body undergoes shot peening treatment (shot diameter 0.8mm, strength 0.3mmA), with a residual surface compressive stress of -400MPa, effectively suppressing crack initiation.
Iv. Compatibility and Quality Standards
Engine compatibility
1.5L GDI turbocharged model: Compatible with Dongfeng's independently developed DFMC15TD engine, the connecting rod1004100F0000 needs to withstand the 1.8-bar burst pressure brought by the turbocharging, so a higher-strength 42CrMo material variant is adopted.
1.8L GDI naturally aspirated model: Compatible with DFMC18 engine, the connecting rod material is standard 40MnBH, balancing economy and reliability.
Compliance and Certification
It complies with Dongfeng Motor's "Technical Conditions for Engine Connecting Rod1004100F0000 Assemblies" (Q/DFL 301 002-2022), and has passed the 1000-hour bench fatigue test (simulating 200,000 kilometers of driving) and the cold and heat shock test (cycling from -40℃ to 150℃).
Meet the EU ECE R111 emission regulation and the Chinese GB/T 23484 reliability standard for automotive parts.
