Abstract
The invention provides the use of a lubricating oil composition for improving the detergency and oxidation stability of an internal combustion engine using a biofuel, the internal combustion engine using a fuel containing at least 1 kind selected from the group consisting of a hydrotreated natural oil or fat, a transesterified natural oil or fat and a hydrotreated natural oil or fat transesterified natural oil or fat, the lubricating oil composition containing 10 to 1000 ppm by mass of an alkali metal borate or a hydrate thereof in terms of alkali metal in the total amount of the composition; the composition can exhibit excellent detergency even when the fuel is mixed or the ash content is low.
Description
The divisional application that the application is application number is 200880112470.X, the applying date is on September 22nd, 2008, denomination of invention is the Chinese patent application of " lubricating oil composition ".
Technical field
The present invention relates to the lubricant composition for internal combustion engine of the so-called biofuel of the product of transesterification reaction used containing natural fats and oils etc.
Background technology
In recent years, about the pollution of vehicle exhaust, reduce particulate matter (PM: particulate) and NO in oil engine, particularly diesel motor
xdeng the countermeasure of environmental pollution that causes of exhaust gas component become important topic.
At present, this countermeasure installs the exhaust gas cleaner such as particulate filter (DPF) or tai-gas clean-up catalyst (oxidation or reducing catalyst) in the car.
But, the automobile installing above-mentioned exhaust gas cleaner is used during lubricating oil for IC engines in the past and must solve following problem.First, coal smoke is attached on particulate filter.Although the coal smoke of this attachment is by oxidation, burning removing, in order to the coal smoke that burns will carry out the rear injection of fuel usually.Therefore fuel increases engine oil thinning, and the performance of engine oil reduces.
And the metal oxide generated because of burning or vitriol, carbonate etc. can blocking filters.Therefore, although the metal ingredient in preferred lubricating oil is as far as possible low, this metal ingredient, mainly from metal detergent or antioxidant, is therefore difficult to not only keep detergency, oxidative stability but also reduce its blending amount.
In order to solve the problem, there has been proposed a lot of scheme, such as disclose a kind of lubricating oil composition used for diesel engine with diesel particulation removing device, it can realize reducing ash content blocking in DPF, can improve the incendivity of the PM of DPF trapping simultaneously, improves its removing efficiency and realize the lubricating oil composition used for diesel engine of the band DPF of DPF long lifetime, it is characterized in that: sulphated ash is below 1.0% weight, sulphur content content is below 0.3% weight, and molybdenum content is more than 100ppm (such as with reference to patent documentation 1).
On the other hand, for the fuel used in automobile, cause the angle of the carbonic acid gas of global warming principal element to consider from reduction, so-called biofuel receives publicity.
This biofuel is the fuel that the product of transesterification reaction of natural fats and oils etc. contains from the compound of natural fats and oils, the carbonic acid gas absorbed in air by photosynthesis as the plant in natural fats and oils source grows, therefore there is regulation: the carbonic acid gas generated by biofuel is not calculated in the increase of global warming gas, belong to carbon neutralization.Therefore, the utilization of biofuel is expected to further increase.
Above-mentioned biofuel for above-mentioned particulate filter is installed automobile in time, engine oil performance is caused to reduce because fuel increases engine oil thinning, and produce because biofuel deterioration is decomposed and the polar compound of generation, therefore cause engine oil oxidation stability to reduce, and the detergency of engine parts is had a significant impact.When reducing Metals In Lubricating composition in order to avoid filter stoppage, this is more insoluble problem.
