Shenzhen will carry out the Euro 5 emission standard.

Following Shandong and Tianjin's demand for heavy-duty diesel vehicles with particulate traps (DPF), Shenzhen has followed suit.But unlike the two, Shenzhen has targeted the Euro 5 models.In February 2017, shenzhen was formed and released by soliciting opinions from various parties.

The living environment of Shenzhen committee and Shenzhen municipal public security bureau traffic police station on heavy duty diesel execution stage 5 national motor vehicle air pollutants emission standards notice "(hereinafter referred to as:" notice "), the request from January 1, 2018, registered in shenzhen sales, and into Heavy-duty diesel vehicles (excluding tractors) should be equipped with a standard model with DPF and above.

According to the reporter's interview, different from shandong and tianjin, shenzhen's heavy card users are very calm about the release of the regulation.But, inexplicably, since the implementation of the policy, shenzhen has seen the phenomenon of no cars, which is why?The back of the "shenzhen model". After that, what are the issues worth discussing?

The sword refers to the local emission standard of Shenzhen.

DPF is the most commonly used and most effective device for dealing with PM (inhalable particulate matter) emissions, the notice said.The filtration efficiency of DPF is generally more than 90%, which can reach over 99%.

July 1, 2017, Shenzhen sales, registration, and transferred to the bus, sanitation trucks, the coach, mail car, car, bus, bus, residue in heavy diesel vehicles such as the airport bus should choose to install particulate trap (DPF) of five or more of the standard model.

From January 1, 2018, the sales, registration and transfer of heavy-duty diesel vehicles (excluding tractors) in shenzhen shall be equipped with the models of the national five and above standard for the installation of particle collector (DPF).The notice does not require consumers to add DPF later in the day, but to leave the factory or turn around.

The installation was completed before entering the city.Installation of DPF device before the three cars is not recommended, because the three cars in the majority with mechanical control, and in use, high sulfur oil still occupy a high proportion, which can cause a DPF frequent clogging and catalyst.The technical requirements of DPF regeneration control too high, it is easy to cause sintering, cracking and other failure, more serious or in regeneration.Out of control in the process, causing fire and safety problems.For China's five cars, the use of electronic control technology allows the fuel to be fully burned, and the emission of black smoke from the exhaust fumes has been affected. The DPF device can be used to effectively control the emission of particles.
