Abstract: The lubricant system in an important integral part of engine. China has always adopted the foreign standards for its engine oil with absence of the oil standards for its independently-made engines. As China was making progress in engine and oil materials technology, the nation was already ready for development of its engine oil standard system in terms of hardware basis and scientific research capability. A total of 15 companies and institutions, including PetroChina Lubricant Company and the Chinese Internal Combustion Engine Society, jointly launched the Chinese Lubricant Standards Alliance Committee (CLSAC). It organized the domestic industrial experts, coordinated the industrial resources. Based on the innovation efforts of years, China has successfully established its first independent diesel engine oil standard -- the D1 Engine Oil Standard. This standard was applicable for the diesel engine lubricants with emissions specified by the National VI or under the National VI. It was also accepted and supported by the domestic original manufacturers of diesel engine equipment. The establishment of the D1 Diesel Engine Lubricant Standard was of great influence to perfection of the quality certification system and standardization of quality control for engine oil products.
