Caterpillar's National IV products are revealed for the first time

About National IV

Each year, several million new non-road diesel engines are added in China, and the total amount of diesel consumed nationwide exceeds 100 million tons annually, of which approximately 20% is used in various types of non-road mobile machinery. These non-road mobile machines are significant sources of nitrogen oxide emissions. A preliminary estimate suggests that they emit over 2 million tons of nitrogen oxides annually...

The "National IV" emission standard, also known as the fourth stage of the pollutant emission standard for non-road diesel mobile machinery, is applicable to all mechanical equipment in the construction machinery industry that uses diesel engines. Including excavators, loaders, bulldozers, rollers, etc.

Compared with the "National III" emission standards, the implementation of the "National IV" emission standards can reduce nitrogen oxide emissions by 13% to 45% and particulate matter emissions by 50% to 94%. The realization of emission upgrades can not only significantly alleviate the pressure of environmental pollution caused by construction machinery and equipment; It is also possible to enhance the environmental protection management of old equipment and accelerate the renewal and iteration of construction machinery. The benefits are obvious and self-evident.

In accordance with the requirements of the Ministry of Ecology and Environment, starting from December 1, 2022, all production, import and sale of non-road mobile machinery with a power of 560kW (including 560kW) or less and the diesel engines they are equipped with should meet the National IV emission standards. From now on, all original equipment manufacturers and agents will no longer be allowed to sell new equipment of 560kW (including 560kW) or less that meets the National III emission standards.

In response to the national call, various automakers and engine manufacturers have recently launched their own National IV products one after another. Some manufacturers have even started selling their National IV products in advance. Unlike most manufacturers, Caterpillar has been rather low-key in launching and promoting its products that meet the National IV emission standards. This time, the photos of Caterpillar testing its National IV products reflect its consistent style, and also demonstrate the responsible attitude of a responsible enterprise towards its customers. This has also filled the outside world with speculation and anticipation for Caterpillar's National IV products.

Four major features: Caterpillar's National IV products occasionally stand out

According to industry insiders, Caterpillar's National IV products inherit the advantages of being powerful, fuel-efficient, reliable, highly efficient in operation, and easy to maintain. Although they do not differ much in appearance from National III products, they actually have their unique features:

First, it is easy to recognize. The "NR4" nameplate mark is added to the names of all models of National IV products to distinguish them.

Second, it is convenient to use. The addition of urea to the National IV equipment is to reduce the emission of nitrogen oxides, thereby achieving the goal of environmental protection. The urea tank is located in the toolbox, which is convenient for users to add urea solution while adding diesel.

The third point is a high attendance rate. The exhaust gas after-treatment device, by adopting special technical means, enables the DPF regeneration of the National IV equipment without the need for dedicated shutdown, that is, seamless regeneration, thereby maximizing the machine's operating time. More importantly, it effectively reduces the maintenance costs for customers.

Fourth, it has good safety. Caterpillar has added indicator lights to the models that use vehicle urea.

Since the United States and Europe entered the fourth stage of emission reduction in 2007, Caterpillar has accumulated considerable experience in low-emission applications. Currently, there are over hundreds of thousands of non-road equipment equipped with post-treatment system engines operating on-site worldwide. The cumulative reduction of nitrogen oxides and soot particles has exceeded hundreds of millions of operating hours, continuously improving Caterpillar's products in practice. Become more stable and reliable. It can be seen from this that Caterpillar has a solid foundation in the development and market validation of products that meet the National IV emission standards.

The revelation of these photos and videos indicates that Caterpillar has made full preparations for the upgrade of non-road National IV emission standards, and the new generation of Caterpillar National IV products is about to be officially launched in the market. Let's look forward together to the moment when Caterpillar's National IV products are finally unveiled.
