14L Natural Gas Engine

Product Overview

This 14L Natural Gas Engine is a core power product co-developed by CAMC Technology and Farizon, engineered specifically for heavy-duty commercial vehicles, engineering machinery, and industrial heavy-load scenarios. Leveraging the core technological achievements of the 2026 CAMC Alcohol-Hydrogen Power Green Ecosystem Partner Conference, it adopts a classic inline 6-cylinder water-cooled structure, balancing exceptional power performance with stringent environmental standards. With a precisely calibrated displacement of 13.67L, a rated power of 397kW, and a maximum torque of 2500N·m, it delivers peak torque across a wide speed range of 950-1400r/min, making it the ideal choice for long-haul heavy trucks, heavy dump trucks, large special-purpose vehicles, and other heavy-load applications. As a benchmark product in clean energy internal combustion engines, it not only meets China VI b emission standards but also achieves breakthroughs in fuel economy and operational stability, serving as a core solution for commercial vehicle enterprises pursuing low-carbon transformation and overseas customers expanding into the clean power market.

Core Advantages

1.Superior Power Output: With a rated power of 397kW and maximum torque of 2500N·m, it outperforms the average level of natural gas engines in the same displacement class. Its low-speed and high-torque characteristics enable easier vehicle starting, climbing, and heavy-load acceleration, significantly improving transportation and operational efficiency.

2.Ultimate Environmental Compliance: Fully compliant with China VI b emission standards, it adopts advanced natural gas combustion control systems and after

treatment technologies, which drastically reduce the content of nitrogen oxides, particulates, and other pollutants in exhaust emissions. It meets the environmental regulations of most countries and regions worldwide, eliminating barriers to overseas market access.

3.Stability & Durability: The inline 6-cylinder water-cooled design effectively controls the engine operating temperature. Combined with a high-strength cylinder block, wear-resistant moving parts, and precision assembly processes, it has passed over 10,000 hours of bench durability testing and 500,000 km of real-vehicle road testing. It features low failure rates and long maintenance cycles, reducing the total cost of ownership for users.

4.High Efficiency & Energy Savings: The optimized air intake system and combustion strategy ensure full combustion of natural gas. Compared with traditional diesel engines, the fuel cost is reduced by more than 30%. Meanwhile, the engine's lightweight design reduces the overall vehicle weight, further improving fuel economy and load capacity.

Customer Reviews

1.Mr. Wang, Procurement Director of a Multinational Logistics Group: "Our company has deployed 500 long-haul heavy trucks in Southeast Asia, all equipped with this 14L Natural Gas Engine. In actual operation, the engine delivers ample power and is not inferior to diesel vehicles when climbing slopes. Moreover, the cost of natural gas fuel is much lower than that of diesel, saving nearly 2 million RMB in fuel costs in half a year. Most importantly, it easily passed the local environmental certification with no market access issues."

2.Ms. Li, Chief Engineer of a Large Domestic Special-Purpose Vehicle Manufacturer: "As a supplier of special-purpose vehicle chassis, we have extremely high requirements for engine stability. The inline 6-cylinder water-cooled design of this engine is very mature. When matched with our concrete mixers, it works continuously for 12 hours under high-temperature and heavy-load conditions, with the temperature always controlled within a reasonable range and almost zero failure rates. Customer feedback is excellent."

FAQ

1.Can this engine be adapted to heavy-duty trucks of different brands?

Yes. We provide standardized installation interfaces and customized adaptation solutions. We have completed chassis matching tests with mainstream domestic and foreign heavy-duty truck brands, including Dongfeng, FAW Jiefang, Sinotruk, and internationally renowned commercial vehicle brands. It can be directly connected to the vehicle production line without large-scale modifications.

2.What is the maintenance cycle of the engine? What spare parts are required for daily maintenance?

The regular maintenance cycle is 20,000 km or 6 months, whichever comes first. The core spare parts for daily maintenance are air filters, oil filters, and natural gas filters. The spare parts have unified specifications, and we have established spare parts warehouses in major global markets, enabling spare parts delivery within 72 hours.

3.Compared with diesel engines, will the power of this natural gas engine be insufficient?

No. By optimizing the intake manifold and adopting high-pressure direct injection technology, the torque output of this engine in the low-speed range is far superior to that of diesel engines of the same displacement. In core working conditions such as heavy loads and climbing, it delivers better power performance, along with lower noise and vibration, improving driving comfort.
