Water cooling two-stroke outboard engine oil

Abstract

The invention relates to water-cooling two stroke outboard engine oil, the weight percentage compositions of components of the engine oil are as follows: 2 to 15 percent of ashless dispersant additive, 0.1 to 2.0 percent of ashless type rust-preventive, 10 to 30 percent of polyisobutylene, diluent agent 8 to 30 percent of kerosene, the left is base oil containing hydrogenation isomerization high viscosity index. The characteristics of the invention are that: the outboard engine oil concocted by the composition has excellent lubricity, detergency property and anlirust property, and can satisfy the lubricating requirement for the high-power outboard motor, and does not contain phosphorus, and is safe and environment-friendly, when the motor runs at idles speed, the exhaust smoke level is low, and the engine oil is useful for the environment protection. According to 250 hours mooring trial for oil production, the composite use performance of the oil in particular to the detergency property of the oil production is better than the imported outboard engine oil, the engine oil reaches the NMMA TC-W3 quality standard of the National Marine Manufacturers Association (USA), and meets the Q/SY RH2106-2005 criteria.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a water-cooled two-stroke outboard engine oil. Background technique [0002] With the development of the national economy, the demand for large and medium power outboard motors has greatly increased. Existing TC-W2 outboard engine oil is used on large and medium-sized outboard motors. The existing problems are: insufficient starting power, prone to ring sticking failures, short service life of the oil, and cannot meet the cleanliness requirements of large and medium-sized outboard motors. , Lubricity side and requirements. At present, the lubricating oil used in most high-power outboard motors in our country is imported from abroad, which is not only expensive, but also extremely inconvenient to purchase. Contents of the invention [0003] The purpose of the present invention is to provide a water-cooled two-stroke outboard motor oil that can meet the requirements of high-power outboard m...
