China's first! Yuchai K08 Guoliu engine passed the regulatory certification

On October 9, China's first national six engine passed the regulatory certification release ceremony held in Nanning, Guangxi. The national authorized testing organization, China Automotive Research and Inspection Center (Tianjin) Co., Ltd. officially handed over the test report and related certificates to Yuchai.

As early as October 1st, the diesel engine K08 model produced by Yuchai passed the 6b stage emission standard certification of China's heavy-duty vehicle country in China Automobile Research Automobile Inspection Center (Tianjin) Co., Ltd., becoming the first domestic 6b stage. The national standard diesel engine for the emission standard certification report.

The certification release ceremony was held in Nanning, Guangxi

China's first national six engine passed the national 6b emission standard certification, marking the comprehensive landing of China's national six emission standards, a milestone for China's environmental protection strategy progress, and Yuchai's major decision-making for "winning the blue sky defense war" The best practice is the concentrated expression of Yuchai's R&D strength and comprehensive competitiveness, which proves that Yuchai's independent research and development and manufacturing technology have reached the world's leading level.

Xing Min, Secretary General of China Internal Combustion Engine Industry Association, Chen Shihua, Assistant Secretary General of China Association of Automobile Manufacturers, Tan Guirong, Executive Vice President of Guangxi Yuchai Machinery Co., Ltd., and Wang Limin, Vice President, attended the conference.

Pass the most stringent emission certification in one step

The national 6b emission standard is China's pollutant emission control standard for road-mounted internal combustion engines, and is regarded as the most stringent emission control standard in history. On June 22, 2018, the Ministry of Ecology and Environment and the State Administration of Market Supervision jointly issued the "Limits and Measurement Requirements for Pollutant Emissions from Heavy Duty Diesel Vehicles (China's Sixth Phase)" (referred to as the National Sixth Emission Standard), and will be respectively In 2020 and 2023, it will be implemented in the 6a and 6b phases.

Compared with the current Euro IV emission regulations and other European and American emission control regulations, the requirements of the National Sixth emission standards in high-altitude emission control, emission warranty period, remote vehicle terminal monitoring, and compliance in use are significantly higher than those of Euro VI emission regulations. Emission regulations.

The K08 model developed and manufactured by Yuchai is certified by the National Testing Center for National Sixth Emissions. It is carried out under the full video surveillance of the Vehicle Waste Control Center (VECC) of the Ministry of Ecology and Environment. From the preparation of the engine and aftertreatment system, the engine platform Frame connection, to the bench emission certification test, OBD certification test, NOx control certification test, vehicle road (PEMS) emission certification, etc., the entire process is subject to video surveillance, is the most rigorous and most advanced emission certification test in history .

Tested by the testing center, the Yuchai K08 model passed the bench emission certification test, OBD certification test, NOx control certification test and vehicle road (PEMS) emission certification, all pollutants fully meet the national six emission standards limit requirements. And successfully passed the most stringent national 6b certification.

K08 model developed and manufactured by Yuchai

The test results show that the nitrogen oxide (NOx) emission of Yuchai K08 engine is 40% lower than the national standard limit requirement, carbon monoxide (CO) and hydrocarbon (HC) emissions are close to zero, and particulate matter (PM) emissions are higher than that of the country. The six standard limit requirements are 80% lower, and the measured maximum number of particles (PN) is only 22.6% of the national standard limit. The emission margin is very large, which lays a technical foundation for further upgrading of emissions in the future.

The Yuchai Guoliu engine will pass the 6b stage certification in one step, which will effectively reduce the repeated research and development investment of China's commercial vehicle country in six stages, and further accelerate the upgrading of China's commercial vehicle emission technology.

Leading the whole world

As the leader of China's internal combustion engine industry, Yuchai adheres to the mission of “creating customer value and fulfilling human dreams”. It always focuses on engine research and development, and is committed to creating engine products with lower emission and better quality through technological innovation, and has realized the country from country to country. The six-emission standard upgrade leads the way.

Up to now, Yuchai has reserved 14 national six-stage engines, of which 10 are diesel engines, 4 are gas engines, and the power covers 100~650 horsepower, including S, K, Y three technical platforms, 6 major product platforms, 11 The series products, the S platform is a medium and light engine, the K platform is a medium and heavy engine, and the Y platform is a light engine. Compared with international similar products, Yuchai products have significant advantages in reliability, economy, comfort, light weight, appearance value, etc., and have the strength to compete with world-class brands on the international internal combustion engine industry stage. Bring a better experience to users at home and abroad.

Yuchai Guoliu series engines are gradually being applied to the market, and it is planned to start mass production of various series of national six engines in 2019 to meet the needs of major automobile factories. (This article is from Yuchai)
