Development of European gasoline engine oil The development of European gasoline engine oil is not much related to the development of automobile emission standards, and it is not as compact as the United States. It is mainly the improvement of automobile performance such as increased power, smaller engine size, higher operating temperature, and gasoline engine Pressurization makes the requirements for lubricating oil greatly improved. At the same time, automobile manufacturers require that the oil change period be extended as the selling point of the car. This will greatly increase the requirements for the stability and clean dispersion of the gasoline engine oil, and at the same time, it will gradually demand improvement of the fuel economy.
European engine oil specifications and the corresponding emission standards are not much related. If there is a very rough connection, then CCMCG4/G5 can meet the requirements of Europe, while ACEA-96/98 can meet Euro, Euro, and even European emission standards. The gasoline engine emission requirements are not limited by the phosphorus content. On the contrary, some manufacturers specify phosphorus content of not less than 0.08%, but there are a considerable number of diesel cars in Europe, if in the future to meet the European emission standards, the need for denitrification catalysts, ACEAB-3 can only meet Europe and can not meet the European emission standards. If the gasoline engine adopts direct fuel injection and energy-saving measures, it needs better denitrification technology. Both require lubricants to reduce the sulfur content. Another feature of the European car engine oil is the extension of the oil change period as a selling point, generally extended to 20,000 km or even 30,000 km.
Development of Japan's Gasoline Engine Oil Japan basically adopts the API standard and does not have much contact with its emission standards. Basically, it uses the latest API standard oil simultaneously with the United States, but its update rate is slower than that of the United States. In the 1970s, the United States built a nationwide expressway network. A large number of container shipments made the CD oil completely incapable of satisfying the lubrication of the container vehicle engine at that time. It was not until 1984 that this large-scale engine test of Mack and Cummins was put into the CE specification.
