Recently, air pollution has swept across the country, and smog has become a hot topic, causing people's concerns about vehicle exhaust emissions to heat up again. A few days ago, the Ministry of Industry and Information Technology announced that it will implement the National IV emission standard across the country on January 1st, 2015 in order to control and reduce the emission of pollutants from automobiles to meet the requirements of energy conservation and emission reduction.
In fact, the news of the implementation of the National IV Standard is no stranger to people. However, no matter the construction of supporting facilities, the cooperation of regulatory systems or the upgrading of engine technology, the industry still faces many challenges: the urea supply system for vehicles has not yet been formed; the quality of diesel fuel is uneven; the engine technology is in urgent need of innovation; The increase in the cost of car purchases also imposes a burden on businesses and individuals. When the owner pays a small investment in a car, how to properly maintain the vehicle directly affects the performance and service life of the vehicle, thus determining the overall efficiency of the vehicle.
As we all know, meeting the country's fourth emission standard requires more advanced engine technology. At present, there are two main domestic technical routes to meet the upgrade of emission standards, namely, the exhaust gas recirculation (EGR) technology and the selective catalytic reduction (SCR) technology. The EGR technology is more suitable for small diesel engines, and the exhaust gas circulating in the engine combustion chamber increases the amount of soot that is smashed into the lubricating oil, which requires the lubricating oil to have strong cleaning and dispersing performance and smoke handling capacity. At the same time, since the temperature of the flue gas is usually high, it also poses a challenge to the thermal stability and oxidation stability of the lubricant. SCR technology is more suitable for medium and large-sized diesel engines that work at high loads for a long time. Compared with the Guosan engine, the engine using SCR technology has higher maximum torque and maximum power, and the engine temperature increases accordingly. In this case, lubricating oils with excellent thermal stability and wear resistance can provide better protection to the engine. No matter which kind of technical route, the upgraded engine has a more precise structure, which makes its operating conditions more stringent, and puts forward new requirements for the performance of the lubricant.
In order to better protect the diesel engine that meets the country's four emission standards, there are also some small “squeaks†in the selection of lubricants. In general, lubricants of APICH-4 grade and above have excellent cleanliness, high temperature resistance, and abrasion resistance, which can help cope with challenges such as increased soot, engine rise, and power increase. As an international brand with 89 years experience in the lubrication of heavy-duty engines, the Mobil Blackhead is specially developed to extend the life of the engine. Many of its lubricants are APICH-4 or higher grades. The enhanced cleaning performance makes the engine cleaner and the parts last longer. The superior thermal stability and oxidation stability properties can help mitigate sludge build-up, deposits, and viscosity increases. The outstanding wear resistance helps to prolong the service life of gears under high speed and vibration load conditions, thus providing more comprehensive and comprehensive protection for the National IV engine.
Leading from the constant pursuit. Since its inception in 1925, Mobil Blackhead has been working closely with the world's leading truck manufacturers and original equipment manufacturers to continuously adjust and improve their technologies, and has accumulated professional experience in providing lubrication for different types of trucks in different markets around the world. It is with professional spirit and rich experience that it can flexibly cope with technological and standard innovations, help the engine to run well under harsh conditions and prolong engine life.
After entering the fourth national era, due to the corresponding increase in input costs of various aspects of fuel, vehicles, and ancillary equipment, how to provide timely and proper maintenance during the use of the truck to achieve the effect of "good car ownership and less money spent" It is particularly important. Mobil Blackhead has superior quality, can provide excellent protection and lasting power for the engine, make the truck run better, longer and longer, and achieve high returns and high returns for the majority of owners and drivers.
