Limited engine fuel consumption engine standard new policy introduced

On February 7, the General Office of the State Council issued the Opinions on Improving the Energy-Saving and Emission Reduction of the Internal Combustion Engine Industry (hereinafter referred to as "Opinions"). This was seen by the industry as a policy to solve the problem of climate pollution such as hazy weather.

According to the Opinions, by 2015, energy-saving internal combustion engine products will account for 60% of the entire society's total internal combustion engine products. Compared with 2010, the fuel consumption rate of internal combustion engines will be reduced by 6% to 10%; and 20 million tons of commodity fuel oil will be saved. Reduce CO2 emissions by 62 million tons, reduce nitrogen oxide emissions by 10%, and use alternative fuels to save 15 million tons of commodity fuel.

Obviously, it is difficult for new energy vehicles to achieve large-scale marketization promotion in the short term, and it is hoped that the improvement of environmental protection issues will be far from reachable. In contrast, the overall upgrading of traditional power is undoubtedly a more pragmatic option.

In the eyes of people in the industry, the country recently introduced relevant measures to control the environment from various aspects such as oil products, engines, and fuel consumption, indicating that it is extremely imminent for motor vehicles to raise the level of environmental protection. This time, the opinions on the internal combustion engine are only behind the traditional power upgrade. Whether or not the implementation effect can be achieved depends on the specific measures and refinement standards.

According to the Opinions, in terms of engine gasoline engines for passenger vehicles, key applications such as direct injection technology, key technologies such as combustion and electronic control should be promoted, and key components such as direct injection fuel systems and superchargers should be developed to encourage 2.0 liters. The following displacements, especially the 1.6-liter or lower ones, adopt supercharged and direct-injection technology for small-displacement gasoline engines to promote lightweight technologies and further promote passenger car subsidy for energy saving.

However, according to Cui Dongshu, deputy secretary-general of the National Passenger Vehicles Association, the flaw of this opinion is that it does not really support small-displacement vehicles and does not really encourage absolute energy-saving and emission reduction.

He believes that the current "opinions" encourages the use of supercharged and direct injection technology for engines with a displacement of 1.6 liters or less. However, in fact, the 1.6-liter supercharged engine is very powerful and can fully support the power demand of Class B vehicles. The end result is that the product models in the encouraged range are too large to meet the national conditions of the Chinese people. It is also not conducive to alleviating traffic congestion and realizing energy saving and emission reduction. "Why Europe develops small cars, its core is absolute energy-saving and emission reduction. China is pursuing profits and GDP excessively, and does not consider the basic functions of energy-saving small cars, alleviating congestion and improving people's lives," said Cui Dongshu.

He proposed to give greater encouragement to small-displacement, low-fuel consumption models with absolute energy-saving and emission reduction, and to implement an encouragement policy that combines energy-saving emission reduction with absolute energy-saving and emission reduction. At present, the policy gives a subsidy of RMB 3,000 to vehicles with a price of less than 1.6 liters and less than 8% of the standard for fuel consumption less than three phases. This type of subsidy is A-class or even a Class B mid-level sedan, encouraging small-displacement low-fuel vehicles. The effect is not prominent. If a subsidy of 3,000 yuan is given to an absolutely low fuel consumption model with an integrated fuel consumption of 6 liters or less, absolute energy saving and emission reduction can be promoted and the environment can be improved.

In fact, the industry generally believes that the "opinions" have a small impact on the passenger vehicle sector, but for commercial vehicles, the proposed goal is too difficult to achieve. According to Chen Wenkai, president of Gasgoo.com, the passenger car has passed market-oriented competition, and the internal combustion engine technology has been selected as the survival and survival of the fittest, while the commercial vehicle industry is flooded with a large number of low-end products. This "Opinion" is precisely for this type of product must be eliminated signal of.

Du Fangci, an advisor to the China Association of Automobile Manufacturers, even bluntly stated that in the commercial vehicle sector, the probability of an energy-efficient internal combustion engine reaching 60% in 2015 is simply not possible. The "Opinions" stated that the limits of fuel consumption and measurement method standards for internal combustion engine products will be formulated, and the limit values, recommended values ​​and target values ​​for fuel consumption shall be clearly defined. Internal combustion engine products that do not meet the limit value standards shall not be produced, sold or used. In this regard, Chen Wenkai believes that at present, many small businesses producing commercial vehicles are sending suitable models to the market to meet the standards for listing. However, products that formally enter the market fall far short of the eligibility criteria. This is also one of the loopholes that should be strictly controlled in the implementation of future policies.

Cui Dongshu also admits that at present, the proportion of backward products in commercial vehicle diesel engines is relatively large, and there are many cases of fake countries and decks in many small and medium-sized cities.

Regarding the “accelerating formulation of access requirements for manufacturers of internal combustion engines” proposed in the Opinions, Du Fangci believes that the government should not interfere too much and only strictly ensure that substandard products are difficult to enter the market and that the effect of the survival of the fittest can be achieved by the market. Manufacturing companies choose.

Du Fangci said that in addition to power upgrades, the upgrading of oil quality and vehicle emissions is also an important condition for enhancing the environmental protection level of motor vehicles. At present, uneven fuel standards across China are one of the reasons why technology upgrading and emission reduction effects are difficult to achieve. In terms of gasoline, Beijing has implemented Beijing standards, and more than a dozen other provinces and cities in Shanghai have implemented national standards. However, other regions still implement national standards. In terms of diesel, most countries still implement State II standards, except for a few regional implementation country standards.

In the aspect of sewage upgrading of vehicles, the I/M method, namely the inspection/repair law, is also urgently needed to be established and improved. It mainly aims at the regular maintenance of existing vehicles and reduces the discharge of pollutants.
