Amidst growing concerns for environmental conservation, green travel has emerged as an irreversible trend globally. This trend aims to significantly reduce carbon emissions in the transportation sector, thereby contributing to the fight against climate change. As a key component of green travel, hybrid technology plays a crucial role. It not only reduces fuel consumption and exhaust emissions but also enhances the fuel economy and driving performance of hybrid electric buses.

Against this backdrop, Yutong Bus successfully developed a new generation of hybrid power systems. Furthermore, the H10 hybrid bus is equipped with the latest DMT (Dual Mode Transmission) hybrid technology, providing robust support for global green travel initiatives.

Detailed Explanation of Yutong DMT Technology

1. Overview of Yutong DMT Technology

Yutong's new-generation DMT technology improves reliability and reduces mechanical failures by eliminating the traditional gearbox. Yutong has also developed high-efficiency, high-power-density ISG and motor in a coaxial arrangement to enhance efficiency and reduce volume. The ISG-motor series-parallel driving mode allows the system to operate in multiple modes tailored to different driving requirements, enhancing adaptability to diverse road conditions and driving scenarios.

2. Conditions of Maximizing DMT Advantages

· High Fuel Prices: The DMT technology intelligently allocates the power output according to driving demands, ensuring that the engine operates in its most efficient range, thereby significantly reducing fuel costs and bringing higher economic benefits to operators.

· Heavy Traffic Conditions: In congested traffic conditions, vehicles frequently require starting and accelerating. The DMT technology leverages the rapid response and high torque output characteristics of electric motors to achieve smoother and quieter starts and accelerations, thereby reducing the engine's operation at less fuel-efficient and higher-emission operating points.

Advantages of H10 Bus with the Hybrid DMT Technology

1. Economic and Energy-saving 

The H10 is equipped with the latest DMT technology, which effectively reduces environmental pollution and significantly enhances green performance by integrating intelligent powertrain control strategies, automatic brake energy recovery technology, and second-generation engine thermal management technology. During vehicle startups and low-speed maneuvers, the supercapacitor powers the drive motor, preventing the engine from operating in inefficient zones. Under medium and high-speed conditions, the engine directly engages in propelling the vehicle, functioning efficiently in high-efficiency zones. Furthermore, in braking conditions, the vehicle converts braking force into electrical energy, which is stored in the supercapacitor. The H10E vehicle control unit intelligently allocates energy between the engine and supercapacitor based on different conditions, optimizing the vehicle's energy management.

2. Safe

(1) Waterproof Performance of Core Systems

The core systems (battery, motor and electric control) of the H10 hybrid bus possesses excellent waterproof capabilities, enabling it to maintain normal operation under harsh weather and road conditions. Even in situations where there is road flooding, the systems will not short-circuit if submerged, allowing the vehicle to continue operating normally with high safety.

(2) ADAS (Advanced Driver Assistance Systems) + IoV (Internet of Vehicles)

By integrating ADAS and IoV technologies, the H10 can monitor vehicle status and road condition information in real-time, providing drivers with more precise and timely driving assistance and warning information, further enhancing driving safety.

3. Eco-friendly 

(1) Eco-friendly Features of Supercapacitors

The H10 employs supercapacitors as its energy storage components, which are primarily composed of carbon materials, conductive polymers, and metal oxides. These materials pose no environmental pollution during production, use, storage, and dismantling, and they can be recycled and reused. Throughout their entire life cycle, the supercapacitors exhibit green, environmentally friendly, and pollution-free characteristics, aligning with the global concept of green transportation.

(2) Carbon Reduction Advantage

By utilizing the DMT technology and advanced energy management system, Yutong H10 can effectively reduce fossil fuel consumption and pollutant emissions, thereby significantly decreasing carbon emissions and aiding in the global battle against climate change.

Yutong Night in Mexico

Yutong Bus, leveraging its advanced technology and refreshed product lineup, has actively contributed to the development of Mexico's environmentally friendly public transportation system. During the "Yutong Night in Mexico" event, Yutong showcased its latest DMT technology, which received high praise and acclaim from the attendees. This event not only demonstrated Yutong's leading position in green transportation and hybrid technology but also provided robust technical support and solutions for a global eco-friendly public transit system.

Wrapping-up 

In the context of the global focus on climate change and the promotion of green travel, we have successfully developed a new generation of DMT technology through independent research and innovation, which we have applied to our H10. The H10 bus with a hybrid system excels in economic energy efficiency, safety protection, and environmental friendliness, meeting the diverse needs of the global market.

Looking ahead, Yutong will continue to adhere to the concept of green travel, continuously launching more advanced and eco-friendly bus products to make greater contributions to global green mobility.
