How will the diesel engine oil requirements be tested in PC-10? Compared with the United States, Europe’s diesel engine emission standards lag about two years, compared with European, United States, and Japan emission standards. Europe implemented the European emission standard in 1992 and implemented the European ó emission standard in 2000. Some changes have been made in the structure of diesel engines. Although the power is mainly increased, the emissions are not as close as the United States, but in order to reduce nitrogen oxides and reduce particulates. Emissions have taken measures such as delaying ignition and raising the top ring, which has gradually increased the amount of soot in the oil. Of course, improving power, adopting turbocharging, intercooling and complex electronic equipment is still the focus of improvement.
The response of European diesel engine manufacturers is not the same as that of the United States to adopt exhaust gas recycling. Of course, everyone considers diesel high-pressure injection and common rail, but other measures to improve emissions have their own considerations. Some use EGR (exhaust gas recirculation), so that the oil products are closer to the PC-9 in the United States, but some major automakers such as Mercedes-Benz do not use EGR, and use deoxidizing catalytic converters and particulate traps. The processing device will use low-S fuel and low-sulfur, low-phosphorus and low-ash lubricating oil, so how to develop it has to be tested. The development of Japanese diesel engine oil Japanese diesel engine oil mainly considers the characteristics of Japanese diesel engines, such as having an external filter device, which has not been linked to emissions for a long time. At present, 70% of them still use CD+ oil. Of course, Japan’s emission requirements have always been much looser than those of Europe and the United States. It was not until 1998 that new specifications were considered to reduce nitrogen oxides and increase soot handling capacity.
