Weichai Power: Let the World Have "Green Chinese Heart"

With the upgrading of China's engine-related industries, industry development such as heavy trucks and construction machinery on the engine industry chain has also been activated and has become the focus of attention in the world. At the same time, under the guidance of the green economy policy, the Chinese engine industry has begun to leapfrog the “green” road, and in the general trend of energy saving and environmental protection, it has gradually mastered the biggest energy saving core advantages of technological innovation.

People often compare the engine to the heart of heavy trucks and engineering machinery as the source of vehicle power. The engine can be said to be the core of the entire chain; during the initial period of the “Twelfth Five-Year Plan” development, the Chinese heavy-duty truck industry and engineering machinery industry will develop rapidly. Gradually returns to the rational stage, which also led to the intensification of brand competition. At the same time, under the market forces, heavy trucks and construction machinery manufacturing brands have also shifted from product competition to energy-saving technology innovation, service competition, and soft power improvement.

As the largest engine R&D and manufacturing enterprise in China, Weichai Power continues to rewrite the development history of the Chinese engine industry under the drive of innovative development concepts. At present, in building a conservation-oriented society and vigorously promoting a new era of “green economy” in energy conservation and environmental protection, Weichai Power has raised the fuel economy of the engine to the level that leads the world. On January 6, 2012, the large-scale series of the Weichai Power National Fuel Experience Camp was kicked off in Weifang, Shandong. This move not only highly reflects the development mission of Weichai Power's “Green Power, International Weichai”, but also leads the in-depth development of a conservation-oriented society in China and enhances the value of users.

Fuel-efficient Action Highlights Weichai's Innovation Value

The person in charge of Weichai Power stated that “Weichai Power actively provides users with an efficient fuel-efficient power solution with innovative technologies, and this activity is a field verification of Weichai engine fuel economy parameters, allowing the majority of users to experience the innovative products of Weichai Engine. "Oil effect." Compared with consumers and dealers who learned the fuel consumption data in written form, the "economized fuel Weichai Bank" national fuel-efficient experience large-scale activities for the first time real-time video real-time fuel consumption live, let the audience intuitively understand that heavy trucks and construction machinery in the driving And operating parameters such as fuel consumption, engine speed, vehicle speed, and water temperature.

Although the low temperature of -5 degrees Celsius and negative #10 diesel fuel have a significant impact on the engine's fuel consumption, Weichai Power Engine's performance in both heavy truck and construction machinery is very good. In nearly two hours of heavy-duty engine testing, Weichai “fuel-saving power” was loaded with 55 tons, and the actual fuel consumption reached 37.1 liters per 100 kilometers, creating a record of the lowest fuel consumption for heavy truck engines. In the fuel consumption test of the loader calibration conditions, Weichai's “power-saving power” finally won the audience again with fuel consumption less than 10.3% per hour.

Weichai's “Power Saver” has such outstanding performance, thanks to Weichai’s powerful engine R&D and leading engine technology.

Taking the heavy-duty engine as an example, the 10 litre and 12 litre standard-loaded engines of Weichai Power currently have significant fuel-saving performance, of which the fuel consumption of the 12-liter engine is reduced by 15.8%, which reduces the transportation cost for the user and creates more economic benefits. It is reported that the D-speed power developed by Weichai Power Innovation avoids the high-speed, high-fuel consumption area and further widens the low fuel consumption area of ​​the engine. When applied to the standard transport vehicle, it has “high power and fuel consumption under common vehicle speed conditions”. Low, long life and low noise are four advantages. Weichai Power introduced the “Powertrain System Optimization Matching Technology” in line with international standards. It matched the D-speed fuel-efficient power with multi-gear transmissions and small-speed single-stage rear axles to change the fuel-saving mode of relying solely on the engine. The economic efficiency of the vehicle has been greatly improved.

In the field of construction machinery engines, Weichai Power further realized the high efficiency and energy saving of the engine through the upgrading of key technologies and the innovation of key technologies. First of all, Weichai Power upgraded its engine body structure. In addition to the PW injection pump, it also optimized the structure of injectors, superchargers, and pistons to ensure further fuel-efficient fuel consumption. Second, Weichai Power is based on the relationship between engine rated speed, maximum output torque and engine fuel consumption, forming the best matching technology for low-speed engine and torque converter, reducing the engine rated speed from 2200rpm to 2000rpm, making the engine's working area from high fuel consumption area to low The fuel consumption area is shifted to achieve power system fuel economy. At the same time, the application of the electromagnetic constant temperature fan enables the fan speed to be automatically adjusted according to the change of the water temperature in the engine return pipe, which greatly reduces the wasted power of the engine fan, thereby reducing the engine fuel consumption.

Weichai Power Leads the Road to Green Economy Development

Weichai Power actively responded to the call of the country for energy conservation and emission reduction, and through continuous innovation in science and technology, development of circular economy, and intensified energy conservation management, the company achieved a strong combination of rapid enterprise development and fulfilling its social responsibility for sustainable economic development, and actively built Weichai Power. Green "energy-saving card.

During the “Eleventh Five-Year Plan” period, Weichai Power Co., Ltd. has accumulated more than 50 new products, and has successively successfully developed high-power high-speed diesel engines that meet the national III, National IV, and National V emission standards and have completely independent intellectual property rights. The indicators are in line with the international advanced level. Among them, the engine currently used in large quantities in the market for the Blue Engine II engine is more than 10% more fuel efficient than similar domestic products. According to industry association statistics, the use of Weichai engines can achieve annual fuel savings of more than 4,800 liters per year when each commercial vehicle is operating 100,000 kilometers. If calculated by one million vehicles, it can save nearly 5 million tons of diesel a year.

While innovating energy-saving engines, Weichai Power is actively exploring the development of new energy technologies. In 2009, Weichai Power took the lead in establishing a strategic alliance for the new energy and power industry for commercial vehicles and construction machinery in China, developed a series of core technologies featuring electric power and electronic control, and for the first time developed two hybrid powertrain assemblies for successful applications. In the six fields of hybrid loaders, excavators, bulldozers, large passenger cars, heavy trucks, and military vehicles, China's commercial hybrid technology has leapt to the world's leading level. The person in charge of Weichai Power stated that “At present, Weichai Power's new energy technology products have been mass-produced. After the application of new technologies, fuel economy has increased by more than 30%, emissions have been reduced by more than 30%, and manufacturing costs have been reduced by 30%. '3X30' comprehensive indicator."

At the same time, Weichai Power's "engine remanufacturing" program has led the industry. As a new thing in China's machinery industry, engine remanufacturing is a high-level form of circular economy. It repairs and reprocesses used engine parts to make it old and new. It ensures that the dynamics and economy and warranty period are exactly the same as the new machine indicators. . The data shows that for every 10,000 remanufactured engines produced, the added value of recycling is close to 360 million yuan, which can save 14.5 million kWh and reduce 600 tons of carbon dioxide emissions. Compared with remanufactured new products, remanufacturing can save energy by 60% and reduce atmospheric pollutant emissions by 70%.
