On February 17, 2013, the General Office of the State Council issued the "Opinions on Strengthening the Energy-saving and Emission Reduction of the Internal-combustion Engine Industry". The opinion points out that by 2015, energy-saving internal combustion engine products will account for 60% of the total amount of internal combustion engine products in the entire society. Compared with 2010, the fuel consumption rate of internal combustion engines will be reduced by 6%-10%; and the remanufacturing of a number of engines for automobiles and construction machinery will be nurtured. Key enterprises; Realize the localization and large-scale production of energy-efficient and environmentally-friendly internal combustion engine main engines and their parts and components manufacturing equipment; Establish policies, regulations and standards system for energy-saving and emission reduction of internal combustion engine products. However, considering that the recovery rate of heavy truck industry is lower than expected, the speed of technology promotion may be lower than expected.
The submission of the opinions also pointed out the direction for the future development of the internal combustion engine, which is specifically expressed in the following aspects:
Gasoline engine: Supercharged direct injection, combustion electronic control, small and light-weighted promotion and application of supercharged direct injection technology, mastering core technologies such as combustion and electronic control, development of key components such as direct injection fuel system, supercharger, and encouragement of 2.0 liters The following displacements, especially those of small-displacement gasoline engines up to 1.6 liters, use supercharged and direct injection technologies to promote lightweight technologies.
Diesel engine: High-pressure injection, supercharged intercooling, post-processing, calibration and matching, electronic control, and diesel engine for passenger vehicles, focusing on the promotion and application of electronically controlled high pressure fuel injection systems, highly efficient pressurized intercooling systems, exhaust aftertreatment systems, and Electronic control technology encourages the development of electronically controlled high-pressure fuel injection systems, high-efficiency pressurization and intercooling, and exhaust after-treatment systems for diesel engines for passenger vehicles.
The light commercial diesel engine focuses on popularizing and applying advanced fuel injection systems such as high-pressure common rail and electronic unit pump, accelerating the popularization of supercharging technology, and mastering vehicle calibration and matching technology.
Diesel engines for mini vehicles accelerate the promotion and application of high pressure common rail fuel injection systems, high-efficiency fuel filtration systems, and booster systems to improve fuel economy and reliability.
Medium- and heavy-duty commercial diesel engines accelerate high-efficiency turbocharging, waste heat utilization, and power turbine technology. Strengthen the mechanical efficiency to improve technology research and development and application, focus on low-friction technology, promote the industrialization of intelligent, modular components, and achieve the optimal allocation of components and powertrain optimization.
In addition to the internal combustion engine, the development of some key components has also shifted toward specialization. The details are as follows: Key electronic components, superchargers, and exhaust aftertreatment devices focus on the development and industrialization of key technologies for electronically controlled fuel injection systems. Application: To improve the supercharger manufacturing level and its own research and development capabilities, focus on upgrading the technical level of gasoline and diesel exhaust gas treatment modules, on-line diagnostic systems, and key gas sensors, and to strengthen coordination and matching of exhaust after-treatment devices with the complete machine.
The relevant requirements for manufacturing energy-saving, alternative fuels, and remanufacturing also put forward requirements: thin-wall casting, precision forging, double-fuel focus on thin-wall casting, precision casting and forging, heat treatment and surface processing and other green manufacturing processes. Actively develop diesel/natural gas dual-fuel, bio-diesel internal combustion engines, and conduct trials of gasoline/methanol dual-fuel ignition internal combustion engines and diesel/methanol dual-fuel compression ignition internal combustion engines. Actively carry out R&D of key common technologies for the remanufacturing of internal combustion engine products, and support the application of key technologies such as surface repair.
Suggestions will directly benefit some component companies, including Weifu Hi-Tech's advantages in fuel injection, supercharger and exhaust post-processing, and Weichai Power's technology in high-efficiency diesel engines and gas alternative fuel engines. Will benefit directly.
