High-Efficiency methanol-powered Range Extender Engine for Advanced Electric Mobility
This cutting-edge range extender system represents a significant leap forward in clean, reliable, and high-performance power generation technology. Designed for electric vehicles and stationary applications, it delivers exceptional thermal efficiency of up to 45%, with motor efficiency reaching an industry-leading 97.44% at peak output—making it ideal for maximizing energy utilization while minimizing environmental impact. Unlike conventional internal combustion engines, this unit leverages Methanol as its primary Fuel source, offering ultra-low emissions and superior cost-effectiveness compared to diesel or gasoline alternatives.
Key features include an ultra-lightweight architecture using aluminum components such as the cylinder head cover, Oil pan, turbocharger intake manifold, and flywheel housing—reducing overall mass without compromising durability. The modular design integrates advanced cooling modules and air-intake systems routed through the crankshaft, enhancing thermal management and operational stability under diverse conditions. Its NVH (Noise, Vibration, Harshness) performance is also class-leading: measured sound pressure levels at 20kW and 150kW are just 70.5dBA and 90.2dBA respectively, outperforming many competitors in both quiet operation and smooth running.
The engine’s core specifications highlight robust engineering: a 5.91L inline-four configuration with bore and stroke dimensions of 112mm x 150mm, delivering 180kW at 2000rpm and a maximum torque of 950Nm between 1200–1500rpm. It operates efficiently across a wide RPM range—from idle at 700±50 rpm to a maximum no-load speed of 2200±50 rpm—with a B10 lifespan exceeding 1.5 million kilometers, ensuring long-term reliability even in demanding environments. The integrated 600V electrical platform supports a rated current of 220A and a peak power output of 150kW, making it perfectly suited for hybrid-electric drivetrains and off-grid power solutions.
One of the standout innovations lies in its emission control strategy. By utilizing M100 methanol—a clean-burning alternative to traditional fossil fuels—the engine achieves near-zero emissions, reducing CO, HC, and NOx levels by over 95%. This makes it particularly suitable for urban mobility, eco-conscious fleet operations, and regions with strict environmental regulations. Additionally, the engine employs closed-loop air-fuel ratio control and multi-point injection technologies to optimize combustion efficiency, resulting in lower fuel consumption and significantly reduced operating costs—up to 40.2% more economical than comparable Diesel Engines.
Designed for versatility, this range extender excels in both mobile and fixed applications. It powers electric buses, delivery vans, and utility vehicles requiring extended range without sacrificing acceleration or responsiveness. In stationary settings, it serves as a dependable generator for construction sites, remote facilities, or emergency backup systems where noise levels and fuel economy matter. Whether deployed in cold climates or high-heat environments, the inclusion of coolant heating ensures reliable cold-start capability without reliance on auxiliary gasoline starters—an innovative approach that simplifies maintenance and reduces complexity.
Users consistently praise the balance between performance, sustainability, and ease of integration. Many note how the compact yet powerful design allows seamless retrofitting into existing EV platforms, while others highlight the dramatic reduction in fuel expenses and carbon footprint over time. With minimal downtime due to its proven longevity and low-maintenance structure, this engine stands out as a future-proof solution for global markets seeking cleaner, smarter energy conversion.
Common questions often revolve around methanol compatibility and real-world efficiency gains. While methanol requires specialized storage and handling protocols, modern fuel systems like those in this engine ensure safe, efficient use. Users report consistent performance even after thousands of hours of operation, validating claims about long-term durability and economic value. For professionals looking to reduce emissions while maintaining productivity, this range extender offers a compelling blend of innovation, reliability, and practicality.
