Universal lubrication oil for miniature tillers

Abstract

The invention relates to universal lubrication oil for miniature tillers. The universal lubrication oil comprises base oil and a plurality of additives. The universal lubrication oil comprises the following components in parts by mass: 89.0-95.0 parts of base oil, 1.0-2.0 parts of ultra-high alkali synthesis calcium sulfonate, 2.0-3.0 parts of overbased sulfurized calcium alkyl phenolate, 1.0-2.0 parts of polyisobutene dibutylene phthalein imine, 1.0-2.0 parts of zinc butyl octyl dithiophosphate, 1.0-1.5 parts of amino thiolactone, 0.7-2.5 parts of a complex antioxidant, 3.5-6.5 parts of a clearing agent and 1.8-3.0 parts of an ash-free dispersing agent. The lubrication oil is used for implementing universality of overall-vehicle lubrication oil of the miniature tillers and the lubrication oil of different miniature tillers; by combining the characteristics of the lubrication oil for the miniature tillers, on the one hand, the key properties such as resisting oxidization and resisting scuffing of cylinder bore are improved; on the other hand, the property excess such as low-temperature requirement is avoided, so that the universal lubrication oil is high in applicability and high in economy.

Description

technical field

[0001] The invention relates to lubricating oil, in particular to a general lubricating oil for micro tillage machines. Background technique

[0002] With the development of agricultural modernization, micro tillage machines have developed rapidly in agricultural production in some areas. Domestic small-scale multi-functional micro-tillers mostly use 2.2-5.88KW diesel engines or gasoline engines as supporting power, adopt independent transmission systems and walking systems, and one main machine can be equipped with various agricultural implements. There are only two categories of lubricating oil for micro tillage machines: internal combustion engine oil and gear oil. The former is used for engines and the latter is used for gearboxes. Nowadays, there are many brands and models of micro tillage machines used in the vast rural areas. According to the different fuels used, micro tillage machines are usually divided into diesel engines and gasoline engines. The...
