High-Performance Natural Gas Engine Series for Industrial and Power Generation Applications
Discover the advanced HMT12F and HMT13F natural gas engine series—engineered for reliable, efficient, and eco-friendly power solutions in demanding environments. These vertical inline six-cylinder engines combine cutting-edge design with robust performance metrics, making them ideal for industrial generators, agricultural machinery, and remote energy systems across global markets. Designed to meet stringent emissions standards while delivering consistent output, this engine family stands out as a top-tier choice for operators seeking durability, Fuel efficiency, and low maintenance costs.
Key features include a single overhead camshaft configuration, an integral four-valve cylinder head, and water-cooled wet liner technology that enhances thermal management and extends service life. The in-line six-cylinder layout ensures smooth operation at varying loads, while the rear gear chamber provides stable mechanical support for long-term reliability. Equipped with a water-cooled turbocharger and specially engineered components like high-temperature-resistant valve seat rings and Oil-saving piston rings, these units minimize wear and reduce hydrocarbon emissions—ideal for compliance with international environmental regulations such as China Phase III (GB20891).
The intelligent control system integrates Woodward PG+ low-pressure gas injection technology with a high-energy ignition system, ensuring precise fuel delivery and optimal combustion efficiency even under fluctuating load conditions. This combination not only improves responsiveness but also reduces unburned fuel and lowers overall emissions—a critical advantage for users aiming to meet evolving emission norms worldwide. With specific fuel consumption as low as 190 g/kW·h, these engines offer superior economy compared to conventional counterparts, translating into lower operational expenses over time.
Each model in the lineup delivers tailored power outputs: from 280 kW at 1500 rpm up to 352 kW at 1800 rpm, allowing flexibility for diverse applications including backup power generation, pumping stations, and mechanical drives. The compression ratios range between 11.5:1 and 12:1, optimized for maximum torque without knock tendency, while bore and stroke dimensions vary slightly across models (128x153 mm or 130x161 mm) to balance displacement and performance requirements. All variants feature a compact footprint (up to 1436x939x1479 mm), weigh around 1078 kg, and operate quietly below 97 dB(A)—a key benefit for installations near residential zones or sensitive areas.
These engines are particularly well-suited for use in regions where clean-burning natural gas is readily available and regulatory frameworks prioritize sustainability. Common applications include standalone power plants, irrigation systems, mining operations, and marine auxiliary propulsion. Their modular construction supports easy integration into existing setups, while the robust design minimizes downtime and maximizes uptime—critical factors for industries relying on uninterrupted energy supply.
Users consistently praise the engine’s ability to deliver steady performance under heavy-duty conditions without excessive noise or vibration. Many report significant reductions in maintenance intervals due to improved internal component materials and better heat dissipation. One operator noted, “After switching to this engine, our generator ran 20% more efficiently and required fewer oil changes—especially valuable in remote locations where servicing is challenging.” Another highlighted its suitability for cold-start scenarios: “Even in sub-zero temperatures, it fires up reliably within seconds—no warm-up delays.”
Q: Are these engines suitable for continuous operation? A: Yes, designed for 24/7 duty cycles with robust cooling and lubrication systems. Q: Can they be adapted for different gas qualities? A: Absolutely—the Woodward PG+ system allows fine-tuning for varying methane content and pressure levels. Q: How do they compare to diesel alternatives in terms of emissions? A: They produce significantly lower NOx, CO, and particulate matter, aligning with Tier 3 and beyond standards globally. Q: Is technical support available outside China? A: Yes, certified engineers and spare parts distribution networks exist in Europe, North America, and Southeast Asia.
