Abstract

The invention relates to a diesel oil additive. The diesel oil additive comprises, by weight, 20-80 parts of a cetane number improver, 3-40 parts of a tension ring caged hydrocarbon pentacyclic[5.4.0.0<2.6>.0<3.10>.0<5.9>]hendecane and 5-50 parts of assistant, and the cetane number improver is alkyl nitrate. The assistant can be one or a mixture comprising more of a solvent, a surfactant, a pour-point depressant, a cleaning dispersant, a smoke eliminating and combustion supporting agent and a stabilizer. The diesel oil additive has the advantages of simple production technology, low price, realization of saving of oil by 1-5% after the addition of 0.1-0.6wt% of the additive to diesel oil, reduction of the oil consumption of diesel engines, effectively reduction of the emission of harmful substances in tail gas, and good use effect.

Description

technical field [0001] The invention belongs to the field of petroleum and fuel, and relates to a novel diesel oil additive, in particular to a pentacyclic hydrocarbon containing strained ring cage type [5.4.0.0 2.6 .0 3.10 .0 5.9 ] Undecane (hereinafter referred to as PCU) is a new diesel additive. Background technique [0002] With the widespread use of diesel engines, the consumption of diesel has increased year by year, which has also led to the increase of harmful emissions from vehicles. Since the emission of harmful substances has a serious impact on the ecological environment, human health and economic development, the Chinese government has successively formulated emission-related regulations to limit the harmful emissions of diesel vehicles. Therefore, further reducing the fuel consumption and pollution of diesel vehicles is an urgent problem to be solved at present. Among many solutions, the use of diesel additives can fully burn the fuel by changing the chemi...
