“给中国发动机量身定做一把尺”

Core Viewpoint - The launch of China's first D1 diesel engine oil standard marks a significant advancement in China's lubricant technology, positioning the country as a leader in the global lubricant industry [2][4]. Group 1: Background and Development - The D1 standard was developed by the "Engine Lubricating Oil China Standard Development Innovation Alliance," formed in 2016, consisting of 13 automotive companies, 23 lubricant manufacturers, and several research institutions [3]. - The initiative aimed to address the limitations of existing international standards (API, ACEA) that do not adequately meet the unique conditions of China's automotive environment [3][8]. - Over eight years, the alliance invested nearly 200 million yuan and conducted extensive research and testing to create a standard with complete independent intellectual property rights [3][9]. Group 2: Key Achievements - The D1 standard has led to the establishment of four national lubricant testing bases and the development of a complete independent evaluation capability [4]. - It has fostered a new collaborative model across the automotive, engine, lubricant, and testing sectors, enhancing the industry's overall innovation capacity [4]. - The standard sets a national quality benchmark, aiding regulatory efforts and improving market order [4]. Group 3: Practical Applications and Testing - The D1 standard has been validated through rigorous testing in extreme conditions across various regions in China, demonstrating its reliability and performance [6][8]. - The collaboration between Weichai and Kunlun Lubricants resulted in a new low-viscosity lubricant that meets the D1 standard, significantly extending oil change intervals from 60,000 km to 120,000 km [7]. Group 4: Industry Impact - The D1 standard represents a shift from reliance on foreign standards to a self-sufficient Chinese standard, providing tailored solutions for domestic engine needs [8][9]. - It incorporates specific metrics for cleanliness, dispersibility, wear resistance, and low-temperature pumpability, establishing a foundational benchmark for diesel engine oils in China [9]. - The standard's implementation has led to a reduction in development cycles for domestic lubricants by 40% and a 15% decrease in costs, while also promoting high-end, green, and intelligent manufacturing practices within the industry [9].
