The Farizon Range Extender System is a cutting-edge power solution engineered for high efficiency, ultra-low emissions, and exceptional durability—ideal for modern electric vehicles seeking extended range without compromising performance or environmental responsibility. This advanced internal combustion engine operates on
Methanol as its primary
Fuel, offering a sustainable alternative to traditional gasoline and
Diesel Engines while delivering superior thermal efficiency, reduced operating costs, and near-zero harmful emissions. At the heart of this system lies an innovative four-stroke, liquid-cooled, turbocharged engine with a total displacement of 5.19 liters, featuring a compact inline-four cylinder configuration (112mm bore × 150mm stroke). Designed for optimal energy conversion, it achieves a remarkable peak thermal efficiency of 45%, outperforming many industry-standard engines. The motor itself boasts a maximum efficiency of 97.44% and maintains an average efficiency above 95% across all operating points—a benchmark that sets new standards in propulsion technology. This range extender unit weighs just 525 kg (without
Oil or coolant), thanks to lightweight materials such as aluminum flywheel housing, an aluminum oil pan, and a composite cylinder head cover—all contributing to improved vehicle dynamics and reduced overall weight. Its modular design integrates machine cooling modules and air intake systems directly through the crankshaft, enhancing airflow management and simplifying maintenance. Additionally, NVH (Noise, Vibration, Harshness) performance has been rigorously optimized: at steady-state operation, sound pressure levels remain below 70.5 dBA at 20 kW and under 90.2 dBA at 150 kW—clearly surpassing competitive models in acoustic comfort. Fuel economy is maximized through intelligent control strategies like theoretical air-fuel ratio closed-loop regulation and multi-point injection technology, which ensure precise combustion for maximum efficiency. Compared to conventional diesel engines, this system delivers up to 40.2% lower fuel consumption, significantly reducing operational expenses over time. Furthermore, by utilizing M100 methanol—a clean-burning alternative to fossil fuels—the engine dramatically reduces CO, HC, and NOx emissions by at least 95%, approaching zero-emission levels and aligning with global sustainability goals. Engine reliability is validated through comprehensive CAE simulations and real-world testing protocols, ensuring a B10 lifespan exceeding 1.5 million kilometers—an impressive testament to robust engineering and long-term value. With a rated output of 180 kW at 2,000 rpm and peak torque of 950 Nm between 1,200–1,500 rpm, this unit provides consistent, responsive power suitable for both urban driving and highway cruising. It also supports a 600V electrical platform with a maximum generator output of 150 kW, making it compatible with next-generation EV architectures requiring high-voltage integration. Ideal for use in electric buses, commercial delivery vehicles, and off-grid power applications, this range extender offers seamless integration into electrified transportation ecosystems. Whether deployed in cold climates where reliable cold-start capability is critical—or in regions prioritizing green mobility—it excels in versatility, efficiency, and eco-conscious design. The inclusion of a dedicated coolant heating system ensures dependable starts even in sub-zero conditions, eliminating reliance on auxiliary gasoline starters. Users consistently praise the system’s quiet operation, minimal maintenance needs, and dramatic cost savings compared to legacy diesel generators. Many report noticeable improvements in fleet uptime, driver satisfaction due to smoother acceleration, and significant reductions in carbon footprint—key factors for fleet managers aiming to meet international emission regulations. Common inquiries often revolve around fuel availability, startup procedures in extreme temperatures, and compatibility with existing EV platforms. While methanol may not be widely available in all markets, its growing adoption in industrial and maritime sectors makes it increasingly accessible. For users concerned about cold weather performance, the built-in coolant heater ensures reliable ignition without additional hardware. Integration with current EV drivetrains is straightforward, supported by standardized voltage and communication protocols. In summary, the Farizon Range Extender represents a paradigm shift in range extension technology—combining high-efficiency combustion, low-emission operation, and rugged reliability in a lightweight, modular package. It stands as a powerful choice for forward-thinking operators worldwide who demand performance, sustainability, and long-term economic viability from their powertrain solutions.
