Abstract

The invention discloses energy-saving type medium-ash diesel oil / natural gas double-fuel engine oil. The energy-saving type medium-ash diesel oil / natural gas double-fuel engine oil comprises mineral base oil, a clearing agent, a dispersing agent, an oxidation and corrosion inhibitor, an auxiliary antioxygen, a friction improver and an anti-foaming agent. The engine oil belongs to a medium-ash type product and can be applied to diesel oil / a natural gas double-fuel engine of commercial vehicles of our country and used as an oil and gas field well drilling engine. According to the energy-saving type medium-ash diesel oil / natural gas double-fuel engine oil, a developed product has a good antioxidant and antiwear property, high-temperature cleaning and dispersant property and alkali maintaining property, and the service life and equipment maintenance period of the diesel oil / natural gas double-fuel engine can be remarkably prolonged.

Description

technical field [0001] The invention relates to an engine lubricating oil, in particular to a lubricating oil used in a dual-fuel engine using diesel and natural gas as fuel. Background technique [0002] Under the dual pressure of global response to climate change and my country's control of air pollution, natural gas vehicles have significant advantages in environmental protection. Natural gas used in automobiles mainly includes Compressed Natural Gas (CNG for short) and Liquefied Natural Gas (LNG for short). Compared with gasoline and diesel, natural gas has a higher heat value per unit, and the combustion products are mainly water and Carbon dioxide, almost free of sulfides, nitrogen oxides and lead, has less pollution to the atmospheric environment (smog and greenhouse gases). Economically, since the price of natural gas is lower than that of crude oil, natural gas has obvious comparative advantages over gasoline and diesel. Against the backdrop of low oil prices, the...
