Gasoline engine oil composition adopting water spray combustion emission reduction technique

Abstract

The invention discloses a gasoline engine oil composition adopting a water spray combustion emission reduction technique. 50 percent by weight of poly alpha-olefin and 50 percent by weight of ester adipate EsterexTM are adopted to be compounded to serve as fully synthetic compound base oil, which is matched with a variety of compound additives, including a friction modifier, a clearing agent, a dispersant, an oxidation and corrosion inhibitor, an antioxidant, an antirusting agent, an anti-foaming agent, an emulsion inhibitor, a metal deactivator and a base-number keeping agent. The composition disclosed by the invention has higher antirusting, wear-resistant, antioxidant and emulsion-resistant properties to solve the problem of engine lubricating oil produced by water spray in a cylinder of a gasoline engine; and moreover, the gasoline engine oil composition has the advantages of excellent low-temperature property, detergency and dispersibility, anti-rusting property, antioxidant and corrosion-resistant properties, emulsion resistance and thermal oxidation stability, high viscosity index, good lubricating property, low volatility and little carbon deposition.

Description

technical field [0001] The invention relates to a gasoline engine oil composition using water spray combustion emission reduction technology, which belongs to the field of engine lubricating oil. Background technique [0002] As people's awareness of environmental protection continues to increase, the regulations on engine emissions are becoming more and more stringent. In order to meet the ever-increasing requirements of relevant emission regulations, new energy-saving and emission-reduction technologies must be explored. The water injection combustion technology in the engine is a new engine combustion technology. As we all know: CO emission is one of the important gas emissions of gasoline engines. When the gasoline engine is working, the root cause of CO generation is from the current cognition that the concentration of oil-gas mixture is too high. Therefore, in order to meet the CO emission requirements stipulated in the new emission regulations, the EFI system must r...
