Emissions of Commercial Vehicles Force Diesel Engine Technology Upgrade to Influence Parts Industry


According to the news, commercial vehicle emissions have to meet the National IV standard, involving the upgrading of diesel engine and related industries' technologies and products. The diesel engine parts industry has the greatest impact, and the most important ones are the electronically controlled diesel injection system industry and the diesel engine aftertreatment device industry. "Especially, the majority of China's heavy-duty trucks are still mechanical pumps, and the actual implementation of the National IV will face the cost pressures of switching electronically controlled fuel injection systems and increasing exhaust after-treatment systems. Engine manufacturers and OEMs are facing huge costs. Pressure, unable to bear the increased costs. On the one hand, if the increase in the cost borne by the user, will eventually be passed on to freight, affecting all aspects of economic activity, with the animal price level." Fuping introduction.

On the other hand, from the conclusions of market research and consulting company market research, the market is not fully able to accept this increase in cost. It can be predicted that in the first half of this year, there will be a rush to purchase the National 3 vehicles. After the implementation of the Fourth National Standard, vehicle sales will decline. The growth of the sales volume of the Fourth National Commercial Vehicle will be relatively slow, affecting the maturity of the Fourth National Product and the growth of related industries.

“If the state can give subsidies to the above-mentioned analysis of the Fourth National Medium- and Heavy-duty Commercial Vehicle (specifically N2 and N3 categories), this problem can be solved. The starting point for policy formulation should be to encourage technology and industry progress to achieve energy conservation and emission reduction. "Yao Ping said.

“In the next five years, the annual sales of medium-sized trucks will be less than 300,000, and the annual sales volume of heavy trucks will be less than 700,000. The national financial funds involved in the three years will be approximately 260, 210, and 16 billion yuan, which is currently fully affordable by the state. With regard to improving the environment, improving bad weather, and reducing the huge cost of future environmental governance, this investment is entirely worth it.” Fuping added.

In addition, from the most important environmental point of view, Fuping thinks: “Although the number of commercial vehicles is about three times less than that of passenger vehicles, single commercial vehicles have much larger displacement and vehicle mileage than passenger vehicles. The overall percentage of exhaust emissions is very high. Therefore, emission regulations and policies for commercial vehicles should be the focus of motor vehicle emissions control.”
