In addition to technical means, people also use laws and regulations to ensure that means of reducing pollution emissions are applied. As a result, various emission regulations emerged to set limits for the discharge of pollutants. Europe has European regulations, the United States has US regulations, and China's road diesel engine emission standards have been implemented to the fifth stage. Before the fifth stage, China's emission standards were similar to European regulations. However, in the sixth stage, that is, the sixth stage of the country, the stringent emission standards of our country exceeded the requirements of the European and American regulations. The Sixth National Emission Standard compared the OBD (Onboard Diagnostic System) restriction monitoring project and the functional testing project compared to the national five stages. A significant increase. SVI also increased the emission warranty period, permanent fault codes, and remote OBD requirements that are not included in the Euro VI standards. The remote OBD will enable the environmental protection department to remotely and real-time monitor the changes in engine emissions, thereby reducing the number of counterfeit emissions. The Sixth National Standard also requires that the engine still meet the emission requirements at an altitude of 2,400 meters, but it only requires 1,700 meters in the European emission regulations. Different from the past, the National Sixth Standard will directly measure the actual vehicle emissions as the passenger vehicle, so that the emission test is closer to the actual use of the vehicle, and the engine emission control is wider in the operating conditions, even wider than the European and American standards. . According to the timetable set out in the draft of the consultation, the implementation time of the S6 emission regulations is 2020. Therefore, the time spent on research and development for engine manufacturing companies and vehicle manufacturers is actually very short. Yuchai Guoliu Diesel Engine Advantage This time, the four models Yuchai ignites are YCK13, YCK08, YCS04, and YCY24. Their common feature is It integrates the most advanced engine technology in the world with the most advanced displacement. It has strong power, low fuel consumption, excellent emission, low noise, light weight, small size, high reliability, long service life, and power coverage of 100 to 560 horsepower. In fact, from this simple and simple sentence, you can have a glimpse of the mystery of Yuchai's six-nation engine. New platform, better quality Among these engines, the YCK08 is an 8-liter engine. Yuchai's engine is about 8 liters, including YC6A and YC6L. YCK08 is a model newly developed by Yuchai for up to 8 liters. Because it is a new development, this engine has absorbed advanced design concepts at home and abroad to ensure the competitiveness of this engine. In addition, Yuchai will use this product to replace YC6A and YC6L engines in the six stages of the country. After the Yuchai product line is shortened, the company will have more energy to ensure product quality. So that these products with inherent advantages will be more outstanding in the development of the day after tomorrow. Higher power, higher horsepower Among the four engines, the YCK13 is a 13-liter product with a preliminary design power of 560 horsepower. The YCY24 is a 2.4-liter product with a preliminary design minimum power of 100 horsepower. In the original spectrum, YC4FB is a 2.5-liter product with a minimum power of 90 horsepower. It can be seen that in the six stages of the country, Yuchai's engine will have higher power and horsepower. New material application, more lightweight, lower fuel consumption Increasing power, in the past, generally means that the engine's cylinder may be thicker and the engine's net weight is higher. However, in the six stages of the country, because it is already more difficult to reduce fuel consumption than other stages, it is necessary to make a fuss about the engine's weight. The release of the off-road engine YC4DK in 2016 is a relatively light-weight engine, which makes it highly competitive. In the early days, Yuchai already had several all-aluminum body engines on the market. In addition, in recent years, many units such as Yuchai and the Chinese Academy of Sciences have stepped up cooperation in the application of new materials. In the six stages of the country, Yuchai will apply high-strength materials to the engine, making the engine lighter, smaller, and more compact. , resulting in lower fuel consumption. Lower maintenance costs When introducing the YCK13 engine, Yuchai proposed that advanced modular design will be adopted, which will reduce parts and increase the versatility of parts. Together with Yuchai's and its subsidiary's joint research and development of long-life "three Filtering, as well as other technical means, the user will greatly reduce the maintenance cost. Joint development, more reliable products Due to the short time and high demand, it has become one of Yuchai’s strategies to speed up product R&D in the six stages of the country's cooperation with OEMs and OEMs. In the six stages of the country, Yuchai's preparation work was done earlier than usual. At present, Yuchai has already reached a strategic cooperation intention with the domestic mainstream vehicle manufacturers for the comprehensive cooperation and development in the six stages of the country. In the future, Yuchai Engine will be more closely matched with the entire vehicle, which will greatly reduce the failure rate at the time of product launch. . At the same time, because Yuchai has set a very high standard for products in the six stages of the country, the selection of components will be more stringent. And through the joint development with the parts suppliers to ensure product development once formed, once in place. Through the full value chain linkage of "parts - engine - complete vehicle", Yuchai's six-engine performance will be more reliable and better. Of course, Yuchai’s six-country engine has just been ignited. Many details have not been revealed yet, and the engine is far from finalized. When Yuchai's National 6th Engine really unveiled its veil, we may be able to truly understand the sincerity of Yuchai's launch.
Polyester coated welding tarps fabric no wax coating, no strong smell, no contamination close to waterproof and highly waterproof. The fabric is more stable and not easy to shrink. The tear resistance is more than 2 times that of cotton canvas tarpaulins. Polyester canvas is great for carport canopy, duck patio tarps and equipment tarps. The utility model can be used as an open storage stowage covering for the harbour and airport at the station. Temporary Tents can be built and crops can be used in the open air covering.

Yuchai National Six Engine Successfully Ignited
Taking a Subversion Step to Decrypt the Yuchai National Engine
Entered 2017, the implementation time of the S6 emission standards specified in the “Limits and Measurement Methods for Vehicle Exhaust Pollutants for Compressed Ignition, Gaseous Fuel Ignition Engines and Vehicles (China Sixth Stage) (Draft for Comment)†Only three years in 2020. At this time, four engines of the Yuchai Diesel Engine that met the national six emission standards ignited and caused great repercussions in the industry. So what is the Sixth National Emission Standard? What are the characteristics of these engines that Yuchai ignites compared with the previous products? What do these engines mean for Yuchai?
