From sources is look, long-term the subject of vehicle oil alternative fuels will come from three aspects: coal based fuels, biofuels, gas fuel. By 2020, total amount will be reached 3,000 tons, the total consumption of automotive fuel 15% ~ 20%, and the eu targets of basic and same. Application perspective from vehicles, vehicle alternative fuel three main: oxygen-bearing fuel (alcohol/ether/ester), synthetic oil (GTL) BTL/CTL/methane gas, gas fuel (syngas/hydrogen). / Oxygen-bearing fuel mature technology, the application of the recent key, general with mixed use advisable. Synthetic oils with existing vehicle technology system and infrastructure security compatible, and is a high-quality environmental fuel. The technology also have greater room for improvement. From the long run, will become a main alternative fuel. Gas fuel, methane gas is the key JinZhongQi with natural gas, for example, by 2020, and China's natural gas supply can reach 120 billion m3 above, such as took 10% used in automobile can replace about 1,000 tons of gasoline and diesel; Syngas is all sorts of primary energy through the gasification processes, made of rich hydrogen gas is all sorts of new fuel car feedgas, also direct vehicle fuel used in motor energy transformation, plays a key role; Hydrogen is a raw material origin is widespread, emissions to zero environmental fuel, is the strategic target of vehicle energy transformation of one. According to the national long-term technology development program, our country will from fundamental scientific research, technical innovation and engineering application frontier development of hydrogen technology implementation on multiple levels of key breakthrough. Auto power transformation and hybrid Auto power system is a complete system, including fuel, engine, power transmission system three main level. According to the life cycle analysis, from the efficiency of oil to the wheels, from the perspective of oil optimal combination is: gasoline/diesel - internal combustion engine - hybrid; From natural gas, coal hydrogen fuel cell and its hybrid can and synthetic fuel internal combustion engine and its hybrid competition. In recent years, auto power system is the biggest breakthrough hybrid technology for car dynamic systems, which laid a foundation platform of transformation. Currently, hybrid cars industrialization is the internal combustion engine power transformation milestone. Using mixed association-like car hybrid system of urban condition can fuel-efficient cars by around 40%. Hybrid car emissions control especially for urban conditions emissions control provides effective new way. View our private cars mainly concentrated in cities, hybrid vehicles also has important energy conservation and environmental protection significance. The auto industry in our country should learn from electronic engine control injection technology accumulated in the transformation of development experience and business models, and through tax incentives and other incentive policy, develop and promote hybrid. In the future, developing hybrid have two technical route worth attention: one is the car hybrid of modularization. Through the development and function modules combination of power to promote the gradual car electrified. From only possesses automatic start-stop, idle shutdown function "micro mix all the" (micro hybrid), with parallel - hybrid engine as the main body of the "light blending" (micro hybrid) and to mix - characterized association-like mixed "(" all full hybrid), along with the power - the proportion of transition to gradual enhancement, eventually tandemvibratory" rechargeable mixed plug - in - "(hybrid). 2 it is a city bus hybrid system of the platform. Generator + drive motor + storage device constitute the basic hybrid system technology platform. Through for a different auxiliary power assembly (the APU) from gasoline and diesel to hydrogen fuel cell diesel engines to different kinds of energy and power conversion device, forming oil, electricity, gas, electricity, electricity - all sorts of different hybrid electric power system, promoting the smooth transition and transformation.
