Doosan of Modern Times: With the arrival of the National IV standard, which construction machinery enterprise will take the lead in the battle?

"Dual carbon" is the abbreviation for carbon peaking and carbon neutrality. As early as 2020, China explicitly put forward the goals of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060. In October 2021, the Central Committee of the Communist Party of China and The State Council issued the "Opinions on Improving, Accurately and Comprehensively Implementing the New Development Philosophy and Doing a Good Job in Carbon Peaking and Carbon Neutrality", elevating the dual carbon goals to a "national strategy". In 2022, an important article in Qiushi Journal, titled "Correctly Understanding and Grasping Major Theoretical and Practical Issues in China's Development", mentioned that achieving the "dual carbon" goals is not something others ask us to do, but something we must do ourselves.

Against this backdrop, the construction machinery industry, which is highly related to the "dual carbon" goals, naturally attracts more attention. Low-carbon transformation and energy conservation and emission reduction have become the "essential needs" of the construction machinery industry. Starting from December 1, 2021, the "National IV" emission standards for non-road mobile machinery have been implemented first in Beijing. On May 1, 2022, Shanghai and Shenzhen implemented it simultaneously. On December 1, 2022, the "National IV" standard will be widely adopted across the country.

The grand goal of carbon peaking and carbon neutrality, coupled with the upgrading of emission standards in the industry, has directly led to the fact that the construction machinery industry is facing new challenges. Of course, from a developmental perspective, this is also a rare opportunity for high-quality development. Astute construction machinery enterprises and practitioners have long begun to take action, regardless of whether the original motivation was active or passive. All kinds of construction machinery enterprises have begun to "show their unique skills" one after another.

Electric speed is slow, and emissions have been upgraded

Unlike the vigorous electrification trend in the automotive industry, the pure electric path of construction machinery seems rather "all talk and no action". Although there have been some actual vehicle applications, its reliability, durability and practical application experience still lack long-term verification. That is to say, it is not in line with the actual situation at the current stage to directly switch from the traditional fuel-powered mode to electrification in a one-size-fits-all manner. Then, with the implementation of the "National IV" emission standards for non-road construction machinery, all construction machinery enterprises still focus on emission upgrades and show a positive attitude.

According to the standards, from National III to National IV, different power segments of non-road mobile machinery adopt different emission control technologies. For the power range of 37kW≤P<75kW, the main technical route adopted is to install a particle filter (DPF). For the power range of 75kW ≤P< 130kW, the main technical route is to install an oxidation catalytic converter (DOC) + particle filter (DPF). The main technical route for the power range of 130 kW≤P<560 kW is to install an oxidation catalytic converter (DOC) + particle filter (DPF) + selective catalytic reduction device (SCR). For diesel engines with a power range of less than 37kW, further optimization of the intake and fuel injection systems is technically required. Compared with the "National III" emission standards, the "National IV" standards can reduce nitrogen oxide emissions by 13% to 45% and particulate matter emissions by 50% to 94%.

Seize the initiative and take the lead in the struggle

Objectively speaking, in terms of the "National IV" emission technology, foreign brands have certain advantages. For instance, Hyundai Doosan Infracore, the first foreign brand to pass the environmental protection approval for the National IV emission standards, has performed quite impressively. As one of the first-tier members of the construction machinery industry, Hyundai Doosan Infracore, in the face of the National IV emission standards, did not passively "wait for the answer", but actively "solve the solution".

By applying the unique ULFC(Ultra Low Fuel Consumption) combustion technology and post-treatment (DPF+SCR) system, the performance is further enhanced and fuel consumption is reduced. Based on this technology, Hyundai Doosan Infracore released several National IV models, including DX150W-10, DX60W ECO, DX75-10, DX60 ACE-10, and DX60E-10, ahead of other brands as early as the beginning of this year. This is also the first batch of excavator products on the market that meet the "National IV" emission standards. Compared with the previous National III products, the new National IV models can significantly reduce the emissions of harmful substances such as NOx(nitrogen oxides), HC(hydrocarbons), and PM(carbon, ash and other particulate matter), seizing the industry's initiative.

Hyundai Doosan Infracore was able to take the lead in making efforts nearly a year before the full implementation of the National IV emission standards. On the one hand, this is because Hyundai Doosan Infracore has accumulated rich experience in the strict emission standards of the European and American markets. On the other hand, as early as the beginning of 2021, Hyundai Doosan Infracore conducted on-site operation tests for all its national IV models across the country. They endured extreme cold and heat, spanning the four seasons, with the longest test duration for a single machine exceeding 4,000 hours. It is precisely because of these capabilities that Hyundai Doosan's "National IV" products have achieved technological leadership and reliable quality.

Strong grass withstands the fierce wind, and true gold shines through the fire. The launch of a series of "National IV" products not only demonstrates Doosan Infracore's advanced level in the field of low-carbon technology for excavators, but also highlights its strong R&D capabilities. We believe that in the future, Hyundai Doosan Infracore, which is "lightweight", will make greater investments in technological research and development and produce more energy-saving and low-carbon "green" products to strive unremittingly for the realization of the "dual carbon" goals!
