High-Efficiency methanol-powered Range Extender Engine for Sustainable Mobility
This advanced range extender system delivers exceptional performance, Fuel economy, and environmental benefits, making it an ideal solution for electric vehicle (EV) applications requiring extended operational range. Designed with cutting-edge engineering principles and a focus on Clean energy innovation, this engine stands out in the global market for its superior thermal efficiency, lightweight construction, and ultra-low emissions. Whether powering commercial fleets or personal EVs, this product offers unmatched reliability and cost-effectiveness.
At the heart of the system lies a high-efficiency internal combustion engine featuring a 45% thermal efficiency rating—among the highest in the industry—and a motor that achieves up to 97.44% peak efficiency, with an average of 95% across all operating points. These figures surpass competitors and ensure optimal energy conversion from fuel to usable power. The modular design incorporates intelligent air intake systems and machine-cooled components, enhancing durability while reducing maintenance needs. Lightweight materials such as aluminum flywheel housing, cylinder head covers, and turbocharger intake pipes contribute to reduced overall mass without compromising structural integrity.
One of the standout features is its low noise, vibration, and harshness (NVH) profile. At steady-state operation, sound pressure levels are measured at just 70.5 dBA at 20 kW and 90.2 dBA at 150 kW—significantly quieter than most comparable engines. This makes it ideal for urban environments where acoustic comfort is critical. Additionally, the use of Methanol as the primary fuel source sets this engine apart: it burns more cleanly than gasoline or diesel, resulting in over 95% reductions in CO, HC, and NOx emissions—effectively achieving near-zero emission standards. This aligns perfectly with global sustainability goals and regulatory frameworks promoting greener transportation solutions.
The engine’s performance parameters reflect its robust engineering. It operates as a four-stroke, liquid-cooled, inline-four configuration with a total displacement of 5.91 liters, producing 180 kW at 2000 rpm and delivering maximum torque of 950 Nm between 1200–1500 rpm. With a B10 lifespan exceeding 1.5 million kilometers, this unit ensures long-term reliability under demanding conditions. Its ability to run on M100 methanol as the main fuel, supplemented by 92# gasoline for cold-starting, provides flexibility while minimizing reliance on fossil fuels. A built-in coolant heating system guarantees reliable ignition even in extreme temperatures—a crucial advantage for year-round operation in diverse climates.
Designed for integration into electric drivetrains, this range extender supports a 600V voltage platform and can generate up to 150 kW continuously, making it suitable for both passenger vehicles and light-duty commercial transport. Its compact footprint and efficient cooling system allow seamless installation in various vehicle architectures, from buses to delivery vans. By leveraging technologies like closed-loop air-fuel ratio control and multi-point injection, the engine optimizes combustion efficiency, leading to a 40.2% improvement in fuel economy compared to traditional Diesel Engines—translating directly into lower operating costs and greater economic value over time.
Users report significant improvements in vehicle uptime, reduced refueling frequency, and enhanced driving experience due to smoother acceleration and minimal noise. Fleet operators particularly appreciate the combination of high durability, low emissions compliance, and reduced total cost of ownership. For consumers seeking environmentally responsible yet powerful alternatives to conventional range extenders, this engine represents a next-generation breakthrough in sustainable mobility technology.
Common inquiries often center around methanol availability, maintenance intervals, and compatibility with existing EV platforms. While methanol infrastructure varies by region, its growing adoption in industrial and marine sectors supports increasing accessibility. Routine servicing follows standard practices for internal combustion engines but benefits from longer intervals thanks to the robust build quality and optimized lubrication systems. Integration with modern electric vehicle controllers is straightforward, thanks to standardized electrical interfaces and real-time monitoring capabilities.
