On June 28, 2012, after the State Council issued the "Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)", the state has successively introduced a subsidy policy on new energy, which has subsequently led to the "new policy" of various local governments. A series of plans for new energy technology development, introduction and infrastructure construction have been issued. New energy subsidy policy points: 1. Hybrid power is only plug-in subsidies. 2. From 2013 to 2015, the cumulative number of new energy vehicles in super-large cities or key regions will be no less than 10,000 vehicles, and the cumulative total of other cities or regions will not be less than 5,000. 3. The proportion of newly-added or updated public transportation, public service, logistics and environmental sanitation vehicles in new energy vehicles shall not be less than 30%. 4. The new subsidy standard will remain unchanged from 2013 to 2015. The issuance of new energy industry development plans is not only a revolution in the automotive industry, but also a test of the engine industry's technological R&D capabilities and market opportunities. Whoever can seize the opportunity of this industry change will be able to meet the challenges and will Become a leader in the wave of new energy auto industry. The application of new energy vehicles on the one hand effectively alleviates the shortage of oil resources, and on the other hand, it solves the problem of environmental pollution caused by vehicle exhaust emissions. Passenger cars, especially city buses, serve as a window for urban transportation, and the application and promotion of new energy buses continue to be strengthened.
Ever since, Yuchai has been committed to being a leader in China's green power, focusing on R&D, manufacturing and manufacturing of green and new energy engines such as natural gas engines and hybrids that meet customer requirements, and has been widely recognized by customers. Since 2004, Yuchai has started research and development of hybrid power. In 2005, Yuchai started a single-axis parallel hybrid powertrain study centered on the core needs of public buses for hybrid buses. In 2007, the city developed a hybrid passenger car (ISG hybrid) successfully. In the following years, Yuchai continuously improved the optimization system. At the end of 2011, it launched the first-generation system upgrade system - YCHPT plug-in. Hybrid second-generation system (YCHPTII) and began mass production on the market.
Yuchai YCHPT plug-in hybrid second-generation system (YCHPTII) inherits the advantages of high integration and high power density of a single-axis parallel hybrid system. It is equipped with a special motor and increases the motor power to 120 kW. Adapting to the dual demands of deep hybrid and plug-in systems, it also fully demonstrates the advantages of high energy feedback efficiency and high fuel economy. It is in line with national new energy subsidy requirements and is the international mainstream technology line. At the same time, YCHPTII uses an "engine + motor" integrated design, which makes the system features a compact mechanism, high mechanical efficiency. Standard AMT automatic transmission, working conditions to adapt to a broader area, with intelligent shift, tiptronic, power/economic mode switching function. In addition to the existing nickel-metal hydride and lithium iron phosphate batteries, the power-storage element has increased the supercapacitor's adaptability. Yuchai hybrid second-generation plug-in system is briefly summarized as follows: a gearbox, a wide range of working conditions; high mechanical efficiency; flexible adjustment of electric power ratio; high fuel-saving rate and stability;
Yuchai hybrid power system has been put into the market so far has been more than 3,000 units, Yuchai hybrid power engine in the domestic hybrid bus market share of up to 70%. The products are supported by major domestic passenger car companies Xiamen Jinlong, Suzhou Jinlong, Zhengzhou Yutong, Guangzhou Automobile Group, Chongqing Hengtong, Jinhua Yaman, Zhongtong Bus, Jiangxi Kaima Bailu, Guilin Daewoo, and so on. The product support is mainly concentrated in 9~12. Mid-size and large-size urban passenger buses are widely used in Guangzhou, Suzhou, Chongqing, Kunming, Hangzhou, Wuhan, Nanchang, Guiyang, Zhengzhou, Hohhot and other cities. Yuchai's hybrid powertrain achieves a fuel saving rate of 25% to 30% in the market. On the majority of customers of all ages.
Facing the increasingly severe demand in the automotive market and increasingly serious product homogeneity, Yuchai will continue to accelerate the pace of technological upgrading, closely follow the development of international technology, seize the development trend of the market, and uphold the sense of corporate mission and society. Responsibility, with "green development, harmony and mutual benefit" as the core concept, leads the way in the new energy power industry.
