Crafted exclusively for the HM180 engine, this piston is a specialized high-power compact heavy-duty part that merges premium materials, precision machining, and model-specific design. Built to match the HM180’s optimized specifications—highlighted by its 62.5mm high-displacement cylinder diameter, 39.7mm ultra-compact total height, and 1.2*1.2*2.5mm heavy-duty piston ring set—it delivers seamless fitment, robust power delivery, and long-lasting performance. Whether you’re craving responsive acceleration, hauling medium-to-heavy cargo (up to 830kg), or operating a commercial tricycle in demanding environments, the HM180 piston is the trusted choice for dynamic balance and reliability. Below, we detail its key specifications, design advantages, and versatile applications to help you make an informed purchasing decision.
CYL DIA (Cylinder Diameter): 62.5mm – Optimized large maximizes displacement for exceptional torque output (16.8 N・m @ 6,400 RPM), enabling the engine to handle loads up to 830kg—40% higher than standard 57mm piston models.
TOTAL HIGH (Total Height): 39.7mm – Ultra-compact design reduces piston weight by 18% compared to traditional heavy-duty alternatives, minimizing reciprocating mass while maintaining structural rigidity for high-pressure operation.
COMP DIST (Compression Distance): 21.2mm – Shortened compression distance fine-tunes the compression ratio to 9.7:1, enhancing combustion efficiency for both raw power and fuel economy.
Piston Ring Specifications: 1.2*1.2*2.5mm – Heavy-duty triple-ring configuration (two compression rings + one oil control ring) delivers superior sealing (46% reduction in gas leakage vs. standard rings) and reduced oil consumption (29% lower), while withstanding high-heat, high-load operation.
PIN DIA (Piston Pin Diameter): 15mm – Robust pin diameter ensures stable power transmission to the connecting rod, withstanding extreme torque loads without compromising the piston’s compact design.
PIN LENGTH (Piston Pin Length): 46.5mm – Optimized length distributes stress evenly across the connecting rod, minimizing wear and extending service life in frequent-use and heavy-load scenarios.
High-Power Load Capacity: The high-strength alloy and reinforced structure enable the piston to handle extreme torque and loads up to 830kg, making it ideal for commercial tricycle cargo transport (e.g., construction materials, agricultural supplies) and high-performance motorcycle hauling.
Compact Durability: Resists corrosion, scuffing, and mechanical fatigue while maintaining an ultra-lightweight profile, extending the piston’s service life to 88,000km—41% longer than generic high-power pistons.
Stable Heat Management: Efficiently dissipates heat generated by high-compression combustion and frequent stop-start operation, preventing engine overheating and maintaining consistent performance in diverse climates (from arid deserts to humid tropical regions).
Raw Material Testing: Ensures the 2024-T6 aluminum alloy meets aerospace-grade standards for strength, heat resistance, and torque tolerance.
Dimensional Accuracy Checks: Verifies critical dimensions (CYL DIA, COMP DIST, ring groove width) using laser interferometry to match the HM180’s exact tolerances—with special focus on piston ring compatibility and compression seal integrity.
Power & Load Testing: Simulates the HM180’s operating conditions (variable RPM, maximum load) to assess torque output, fuel economy, and compression retention under stress.
Sealing & Wear Tests: Validates the heavy-duty piston ring’s sealing capability and the piston’s wear resistance over 17,000 simulated kilometers of high-performance, heavy-load operation.
Structural Integrity Testing: Ensures the ultra-compact design withstands 15,000+ load cycles without deformation or premature failure.
For medium-to-heavy duty tricycles powered by the HM180 engine (popular for commercial cargo transport, passenger shuttles, and rural logistics), the HM180 piston is a high-performance, cost-effective solution. These tricycles require a mix of power and maneuverability to handle loads up to 830kg, and this piston’s 62.5mm optimized ,ultra-compact design, and heavy-duty piston ring set ensure stable performance in diverse conditions. It operates reliably in both congested urban streets (with frequent stops/starts) and rough rural roads (with uneven terrain), making it a top choice for small business owners and independent operators who value power, efficiency, and minimal downtime.
Rigorously tested for durability under high-torque and heavy-load conditions, the HM180 piston’s premium materials and precision design minimize wear on the cylinder wall and connecting rod, extending its service life to 88,000km—41% longer than generic high-power heavy-duty pistons. This reduces maintenance frequency (service intervals extended from 5,000km to 8,500km for commercial use) and replacement costs, making it an ideal choice for both performance enthusiasts and commercial operators who rely on their vehicles for daily use.
