摘要： A lubricating oil for diesel engines is disclosed. This oil is based on a mixture of lubricating mineral base oil and a highly aromatic light base oil, and is highly effective in reducing the wear of the diesel engine designed to run with heavy fuels having high carbon to hydrogen ratios. The oil is also advantageous in that it does not clog the lubricant filter.

摘要： An apparatus for detecting the deterioration of an engine oil including a ceramic heater radiating infrared light including infrared radiation having a wavelength of 6.1 micron meters which is equal to the specific infrared absorption peak of ester of nitric acid contained in the engine oil. The infrared light is made incident upon a photodetector via a band pass filter having a center wavelength of 6.1 micron meters to detect an amount of the ester of nitric acid contained in the engine oil. It has been experimentally confirmed that an amount of the ester of nitric acid is proportional to the total acid value which is a measure of the deterioration of the engine oil, so that by suitably processing an output signal of the photodetector, it is possible to detect the deterioration of the engine oil. The thus detected deterioration may be displayed on a display device provided on a front pedal of a car.
摘要翻译：一种用于检测包括陶瓷加热器的发动机油的劣化的装置，该陶瓷加热器辐射包括具有6.1微米米波长的红外辐射的红外光，其等于包含在发动机机油中的硝酸酯的特定红外吸收峰。红外光通过中心波长为6.1微米的带通滤光器入射到光电检测器上，以检测发动机机油中所含的硝酸酯的量。经实验证实，硝酸酯的量与作为发动机油劣化量的总酸值成比例，通过适当地处理光电检测器的输出信号，可以检测发动机油的劣化。这样检测到的劣化可以显示在设置在汽车的前踏板上的显示装置上。
