The automotive industry is ushering in a major trend. Under the requirements of energy saving and environmental protection, the upgrade of diesel vehicle emission standards is being pressed harder and harder. This is forming a new outlet. For engine companies, whoever is able to take the lead in the market and take the lead in seizing this opportunity will be able to stand on this cusp and learn new strengths to shed new vitality in new markets. As the leading brand in the domestic engine industry, Weichai clearly has a big picture, taking the lead in strategically deploying the natural gas engine market, taking advantage of the launch of the WP7 natural gas Euro VI engine, and adding scientific and technological strength to the success of the domestic engine industry.
Which level is Euro VI?
The comprehensive upgrade of the four emission standards of diesel vehicles has made domestic engine companies pay more attention to technology. How to grasp the core technology, and promote the upgrading of products through technological changes so as to stay at the forefront of the market, become the engine of the latest issues.
At the 2015 Beijing International Road Transport, Urban Bus and Spare Parts Exhibition, the Weichai Group displayed the WP7 natural gas Euro VI engine that attracted numerous audiences. So what exactly is Euro VI? It is not difficult to understand the information, Euro VI is the sixth phase of European truck and bus emissions standards. It is a vehicle exhaust emission standard that was promulgated and implemented in January 2013 by the EU countries to limit the harm to the environment caused by pollutants emitted by automobile exhaust. Euro IV requires that the mass of carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NO2), and PM particles emitted by the engine per kilowatt-hour of power must not exceed 1.5 grams, 0.13 grams, 0.5 grams, and 0.01 grams, respectively. . Compared with the current domestic four-emission standards for commercial vehicles, the Euro VI engine's emissions per kilowatt hour can be reduced by 2.5 grams, 0.42 grams, 3 grams, and 0.02 grams, respectively. At the same time, domestic emission standards are generally formulated with reference to European standards.

With the gradual stricter national requirements for energy conservation and environmental protection, the requirements for engine emissions will inevitably increase. At the same time, the demand for natural gas as a clean energy source will also increase. Therefore, the natural gas engine that meets higher emission standards will usher in a development boom.
Focus on the future of science and technology
In the coming trend, Weichai has demonstrated its leading technology style with a vision of the future. The WP7 natural gas engine in the end has what kind of technology mystery? Exhibition site, China Truck Network reporter learned through Weichai staff, Weichai WP7 engine has passed VI certification in March 2014, the implementation of this certification by The accreditation officer arranged by the British Ministry of Transport came exclusively to the Weichai Group through on-site operations through a rigorous audit and inspection process. The WP7 natural gas engine on display here adopts the EGR+DOC+SCR post-processing route and a highly integrated ignition coil. On the one hand, the DOC post-processing system is responsible for eliminating the HC and CO in the tail gas and converting it to uncontaminated CO2 and water vapor through catalytic oxidation. The EGR post-treatment system reduces the combustion temperature in the combustion chamber while PM particles are sent to the combustion chamber of the engine for reburning, thereby reducing NOX emissions. The last remaining portion of the excess NOX was catalytically reduced by the SCR urea post-treatment system to convert it to nitrogen. On the other hand, the highly integrated ignition coil can increase the ignition energy by 30%, which can effectively reduce the generation of CO, HC, and PM, make the natural gas more fully burned, and improve the dynamic and economical performance of the engine. The processing system realizes Euro VI emissions of the engine.
WP7 natural gas engine that meets Euro VI emission standards
Talking about why the WP7 machine that meets Euro VI emissions was launched, the person in charge of Weichai said: “There are two main reasons why we introduced the Euro VI engine. The first is that people don’t own it and they have not produced any other engine manufacturers. The engine of Euro VI emission has demonstrated to the user the strength of Weichai's technology reserves, allowing users to be assured of quality when purchasing Euro VI products. Second, we must be familiar with people, and we will provide users with the EU VI standard when it is actually implemented. Provide better performance, more mature technology, lower production cost of the engine products.On the basis of real guarantee of product quality, we further expand the existing market share of Weichai engines through reliable products, and hope that Weichai is now and in the future All can provide users with higher quality and lower price engine products."
Under the trend of energy conservation and environmental protection, it is the trend of the times that the dance can only be based on the frontier of the market. Weichai Group demonstrated this with its scientific and technological strength. Domestic engine companies need to have a forward-looking vision and strength. As an independent brand enterprise, they should try to integrate products with the international market in order to maintain their competitiveness and brand power in a broader market environment. Obviously, relying on WP7 Euro VI natural gas engines and other cutting-edge products in the high-tech market, Weichai Group is quietly laying out its international strategy.
