Abstract

The invention discloses a diesel engine exhaust gas cleaning and energy-saving agent comprising the following raw materials in parts by weight: methanol, ethylene glycol monomethyl ether, polybasic crude alcohol, 5-7 parts of sodium dodecanol sulfate, a carbon deposit scavenger, a desulfurization catalyst, a diesel catalyst, ethyl alcohol ether amine, a diesel power accelerator, decanoic acid glyceride, glycerol palm kernel fatty acid ester, and an ester pour point reducer. The carbon deposit scavenger is composed of a raw oil pour point reducer, an overbased synthetic calcium sulfonate detergent, a viscosity index improver, naphthenic acid and base oil; the diesel power accelerator is composed of isooctanol, aminoacetaldehyde diethyl acetal, n-propanol, zinc naphthenate and pentamethyldiethylene triamine; the ester type pour point reducer is composed of a poly alpha-olefin type pour point reducer and a fumarate type pour point reducer. The invention reduces the emission amount of pollution gas, prolongs the service life of the engine, protects the combustion and fuel injection system of the vehicle, reduces the maintenance cost of the user, has low production cost, and has a widesource of raw materials.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment, in particular to a diesel engine tail gas cleaning and energy saving agent. Background technique [0002] Diesel engines have obvious advantages over gasoline engines in terms of power, economy and reliability, especially low carbon dioxide emissions, and their applications have been extended to various types of vehicles. However, the biggest problem of diesel engines is the serious emission of nitrogen oxides and particles. With the increase of national supervision and the awakening of people's awareness of environmental protection, it is necessary to install three-effect purifiers and electronic injection closed-loop controllers on the exhaust system of diesel engine exhaust. It is one of the measures to effectively solve the pollution of automobile exhaust, but most of these equipment can only purify granular media, and the purification effect on carbon monoxide and hydro...
