This study mainly discusses the HDEO developed specially for individual OEMs and the methodology needed to develop new HDEO to meet the
requirements of the next generation engines which meet the emission control of China national emission standard phases Ⅳ and Ⅴ.

In China, technologies of engine design are also intended to meet the stricter regulations of emissions control. But different OEMs tend to favor different technologies depending on their own in-house technologies and that of their partners. So HDEO (Heavy-Duty Engine Oil) marketers in China must qualify their products to meet both API (American Petroleum Institute) licensing standards and individual OEM specifications. From a technology viewpoint, and in an effort to control HDEO development costs, we are likely to support developing OEM-specifications other than API specifications.

From table 1 we can see the emission control regulations updated rapidly in recent years in China and the gap of emission regulations between China and Europe is narrowed. For EURO Ⅱ and Ⅲ, in-cylinder technologies will be enough to meet these emission regulations, but for Euro IV and V after-treatment technologies of engine designs have to be taken to meet the stricter emission regulations. In China, different OEMs tend to favor different technologies depending on their own in-house technologies and that of their partners to meet China national phases Ⅱ and Ⅲ emission regulations. It is still not sure which after treatment technology will be widely adopted to meet China national phases IV and V emission regulations. It becomes very difficult for oil formulators to develop low emission HDEO to meet versatile requirements coming from China domestic OEMs.

ABSTRACT
Regulations to reduce emissions worldwide are the driving force behind the modifications that OEMs (Original engine manufactures) are making to their engine designs, which in turn drives the need of changes in lubricant requirements. To meet the emission standards, engine makers are turning to after-treatment devices that supplement EGR (Exhaust Gas Recirculation). In the United States, engines are being equipped with DPF (Diesel Particulate Filters), while in Europe SCR (Selective Catalytic Reduction) is favored.
oil was published in 1985 based on the same requirements from ASTM (American Standard and Testing Material) test methods and SAE (Society of American engineer) standards. The version of the first diesel engine oil was named as GB5323-85 (including API CA diesel engine oil). Then in the following two decades, the Chinese national standard for HDEO has gone through series modification in pace with the API CA to CD category development.
The standardization work for Chinese diesel engine oil was started in 1980s as an API categories follower.

BACKGROUND OF CHINESE HDEO DEVELOPMENT
The Chinese automotive industry is developing rapidly in recent years and lubricant standards are closely following the US API categories. With advanced automobiles and engine technologies from abroad, heavy duty diesel engines show lubricant demands on pace with developed countries, markets. Even API CI-4 is available domestically. But due to un-balanced economic development, domestic automotive lubricants co-exist with high, medium, and low tiers.
INTRODUCTION
The Chinese automotive industry is developing rapidly – over 50 million vehicles currently on the road. Automotive exhaust has become significant source of air pollution in big cities. NOX exhausted by automobiles has accounted for 50% of NOX contained in atmosphere. CO exhausted by automobiles has accounted for 85% of CO contained in atmosphere (1). Particulates and NOX are the main pollutions produced by diesel engines.

In China, the National Environment Administration, beginning in 1983, has issued a successive series of emission control standards that essentially established a system of vehicle emission control standards. GB17691-2001 regulates limits and measurement methods for exhaust pollutants from Compression Ignition (C.I.) engines, which is Chinese emission control regulation phases Ⅰ and Ⅱ ， whereas GB17691-2005 regulates Chinese emission control regulation phases III, IV and V for compression ignition and gas fuelled positive ignition engines of vehicles. These are all adopted from Europe emission standards. Table 1 compares the emission regulation progress of heavy duty diesel engines in China to Europe.
