The development of gasoline engine oil in Europe The development of gasoline engine oil in Europe is not very related to the development of automobile emission standards, and it is not as close as the United States. It is mainly the improvement of automobile performance such as increased power, smaller engine size, higher operating temperature and gasoline engines Supercharging greatly increases the requirements for lubricating oil. At the same time, automobile manufacturers require extending the oil change period as a selling point of automobiles, which greatly increases the requirements of gasoline engine oil for oxidation stability and cleanness and dispersion, and also gradually requires improvements in fuel economy.
The European internal combustion engine oil specifications are not very related to the corresponding emission standards. If there is a very rough connection, then CCMCG4/G5 can meet the European requirements, and ACEAA-96/98 can meet the Euro, Euro or even Euro emission standards. , The emission requirements of gasoline engines have no phosphorus content restrictions. On the contrary, some manufacturers stipulate that the phosphorus content is not less than 0.08%, but there are quite a few diesel cars in Europe, if they meet the European emission standards in the future, they need a denitrification catalyst. ACEAB-3 can only meet the European ó but not the European emission standards. If gasoline engines adopt direct fuel injection and energy-saving measures, better nitrogen removal technology is needed. Both require lubricating oil to reduce sulfur content. Another feature of European car oil is to extend the oil change period as a selling point, which is generally extended to 20,000 km or even 30,000 km.
The development of gasoline engine oil in Japan Japan basically adopts the API standard, which has nothing to do with its emission standards. It basically adopts the *new API standard oil at the same time as the United States, but its update speed is slower than that of the United States. In the 1970s, the United States built a national highway network, and a large number of container transportation made CD oil completely unable to meet the lubrication of container truck engines at that time. Therefore, it was not until 1984 that such large engine experiments of Mack and Cummins were put into CE specifications.
