Weichai has the honor to play the protagonist of this development process. In energy-saving and emission-reduction, Weichai has also become an important member of this battle's main camp with its responsibility to the country and society. In 2014, Weichai's engine plate product R&D investment reached 1.407 billion yuan, completed the full range of vehicle IV and V diesel engine emission certification development, WP3 two-valve IV vehicle diesel engine went on the market in small batches, and the automatic ECU electronic control system succeeded. Supporting natural gas engines, the WP13 high-powered heavy-duty commercial vehicle engine was released and launched. 562 patents were filed throughout the year, including 145 invention patents. In China, heavy trucks that account for only 5% of the total number of vehicles emit more than 60% of CO2, while only 1.5% of heavy trucks in US vehicle sales consume more than 70% of diesel, and engine thermal efficiency reaches 50-55%. To improve fuel efficiency and reduce emissions, there is a long way to go for the Chinese internal combustion engine industry. As the only powertrain provider in China, Weichai integrated industry resources. After system optimization and matching, the vehicle assembly efficiency of Weichai Powertrain assembly was increased by 30% and fuel consumption was reduced by 10-15%. At the same time, the formation of the R&D team of Weichai Qianren and the R&D structure of “five countries and ten places†provide a reliable guarantee for the development of energy-saving emission reduction and recycling economy. Currently, Weichai is improving fuel system optimization, injection pressure, and fuel injection law, adopting new combustion technology, variable cross-section boost technology, two-stage boosting technology, and PBS technology, and improving fuel efficiency through powertrain optimization. , reduce nitrogen oxide emissions. We have spared no effort in investing in new technologies and new products, which has enabled Wei Chai's product development to continue to bear fruit. Through the integration of the four systems of the company's WOS operating system, global R&D community, global supply chain system, and full lifecycle membership-based service system, Weichai built a smart power platform and became an incubator of new enterprise products. With the introduction of the standard WP13 engine, the SCR exhaust treatment technology with lower explosion pressure was selected on the emission technology route, bringing China's heavy-duty engine into a new era of 13-liter aircraft. At the 2015 annual business meeting, Weichai has launched more than a dozen new products such as truck power, construction machinery power, and passenger car power. It has an overall layout from 3L to 13L, ranging from light to medium-sized and heavy-duty engines, and fully meets the requirements of the country. Four emission regulations require. Facing the upgrading of emission regulations, Weichai has made adequate preparations for its products and technology. Weichai has been dedicated to the research and development of alternative fuel internal combustion engine products. Weichai LNG (liquefied natural gas) power has been widely used in the field of long-distance passenger cars, wide-body dump trucks, heavy trucks and construction machinery. In 2014, it sold 51,000 units. The growth rate exceeds 30%. From the perspective of developing a recycling economy, remanufactured parts are highly economical and practical. Compared with manufacturing new products, remanufactured products can generally save costs by 50%, save energy by 60%, save materials by 70%, and the price is only 50% to 70% of new products. Weichai established a remanufacturing company in 2008. It is one of the first batch of 14 auto parts remanufacturing pilot companies confirmed by the National Development and Reform Commission. In March 2012, it passed the first batch of remanufacturing pilot acceptance, and was elected to the National Development and Reform Commission and Finance in 2015. The Ministry of Industry, the Ministry of Industry and Information Technology, the Ministry of Commerce, and the General Administration of Quality Supervision, Inspection and Quarantine organized a pilot enterprise for remanufacturing products that was “for the pastâ€, and 30 engine models were short-listed for “replacement with old†and promote the list of replacement product models. Create APEC Blue, Weichai has been on the road In addition to transforming development methods, accelerating industrial restructuring, and improving the ability of independent innovation to support the transformation and upgrading of the internal combustion engine industry, Weichai also paid attention to the energy-saving and material-saving of the internal combustion engine production process and achieved green production. In the plant of Weichai Industrial Park, 24,750 250W photovoltaic modules were installed, with a total installed capacity of 6100kWp and a building photovoltaic area of ​​73,000 square meters.
