The internal combustion engine is the dominant power equipment for transportation, construction machinery, agricultural machinery, fishing vessels, and defense equipment. The internal combustion engine industry is an important basic industry. After years of development, China's internal combustion engine industry has made considerable progress, and the level of energy-saving and emission-reduction technologies for internal-combustion engine products has been greatly improved.

The internal combustion engine industry has great potential for energy saving and emission reduction.
Strengthening the energy-saving and emission-reduction of the internal combustion engine industry, promoting the conservation of petroleum resources and improving air quality still requires more efforts in key areas. The State Department instructed that by 2015, energy-saving internal combustion engine products account for 60% of the entire society's internal combustion engine products. Compared with 2010, the fuel consumption rate of internal combustion engines will be reduced by 6%-10%, and 20 million tons of commodity fuel oil will be saved, reducing CO2 emissions. 62 million tons, reducing nitrogen oxide emissions by 10%, using alternative fuels to save 15 million tons of commercial fuel; fostering a number of remanufacturing key enterprises such as automobiles and construction machinery engines; realizing the production of energy-efficient and environmentally friendly internal combustion engine Localization and large-scale equipment; establishment of policies, regulations, and standards for energy-saving and emission reduction of internal combustion engine products.
