From July 1st, 2019 to the present, this period of time is a special day. Shanghai people are being mad by garbage sorting. Beijingers are about to start to rack their brains to sort garbage, and the engine and related fields of automobiles and machinery are also Start "talking about emission variability."

So how strict is the country six?

The National 5 standard only makes some limits on the discharge of various pollutants, while the National Sixth Standard not only increases the emission limit, but also introduces the vehicle license plate emission test requirements, and increases the actual road emission test requirements and limits of the vehicle.

Compared with the national five, the emission limit of the national diesel engine pollutants is more stringent. Where do you see the specifics?

National 5, China's six diesel engine pollutant emission limits National 5, China's six diesel engine pollutant emission limits

The pollutants in the above figure are THC (hydrocarbon), CO (carbon monoxide), NOx (nitrogen oxide), NMHC (non-methane hydrocarbon), N2O (nitrous oxide), PM (fine particles), PN ( Particle particles)

From the specific numerical point of view, in the national six a standard, for the emission of diesel engine NOx (nitrogen oxides), it is necessary to meet the emission standards of gasoline engines. The National Five has no requirements for the emission of N2O (nitrous oxide), and is strictly limited in the standards of the National Sixth.

Known as the most stringent standard in history, the National Sixth B, the emission standards for THC (hydrocarbons), NOx (nitrogen oxides), NMHC (non-methane hydrocarbons), and PM (fine particulate matter) are further stringent standards. .

Faced with such strict emission standards, each engine company has adopted different technical means, and the main processing technology adopted by Shangchai Power is: DOC+DPF+SCR+ASC

Seeing this pile of professional abbreviations, everyone has no idea. In fact, each technology has a unique advantage in the treatment of relevant pollutants. DOC (oxidized catalyst) is mainly used to deal with carbon monoxide, DPF (wall flow type particle trap) is mainly used to capture particulate matter, SCR (selective catalytic reduction technology) is mainly used to deal with oxides, and ASC (ammonia gas oxidation) The catalyst is to prevent ammonia leakage. In addition to these technologies, Shangchai Power has also upgraded its engine body, including the fuel system.

No fear of the most strict country, six b, Shangchai Power has been first

For engine manufacturers, each time they meet the emission standards, they are the moments that reflect the company's technology and comprehensive strength. Shangchai Power has already been at the forefront in product development for the country's six technologies.

Shangchai Power has not only a number of products in line with the national six standards, but also M, R, H, E series products that meet the most stringent national six b emission standards, in addition to natural gas engines are also widely used in many fields.

Recently, a number of cities have started the implementation of the National Six Standards in advance, almost in sync, and some of the products of Shangchai Power have been delivered.

Hongyan Jieshi C6 LNG port tractor is equipped with SAIC blue core power LNG engine Hongyan Jieshi C6 LNG port tractor is equipped with SAIC blue core power LNG engine

The newly launched Hongyan Jieshi C6 6X4 LNG coal/sand gravel transport tractor, Hongyan Jieshi C6 6X4 LNG hazardous chemicals transport vehicle, Hongyan Jieshi C6 6X4/8X4 LNG intelligent muck, red rock Jieshi C6 The four models of the LNG port tractor are equipped with the SAIC Blue Core Power LNG engine. This engine is made up of SAIC Power combined with domestic heavy truck subdivision conditions, combined with international well-known brand suppliers, tailor-made for users.

Compared with similar products, SAIC Blue Core Power LNG engine uses clean energy natural gas as fuel, which not only improves transmission efficiency by 5%, but also reduces fuel consumption by 3%-5%, better transmission effect and higher fuel economy. Bring higher economic returns.

With the full implementation of the country's six in the country, Shangchai Power will have more new products. In addition to meeting the national environmental standards, Shangchai Power is also ready to accept the user's actual use of the product.
