Abstract

The invention relates to a mixed fuel for diesel engines. The mixed fuel comprises the following components in percentage by volume: 20-40% of n-amyl alcohol, 20-40 % of biodiesel and 30-50% of petroleum diesel, wherein the sum of the percents by volume of the three components is 100%. According to the mixed fuel, the n-amyl alcohol is used as oxygen bearing adding component of the biodiesel and the petroleum diesel, so that the oxygen content of the mixed fuel can be effectively improved, the complementarity of the n-amyl alcohol and the biodiesel can be developed, the synergistic interaction of the components is realized and the benefits of sufficiently combusting and reducing exhaust emission can be achieved without adding other components of auxiliaries. The mixed fuel provided by the invention can be directly applied to any diesel engines without carrying out any transformation on the engines.

Description

technical field [0001] The invention relates to the fields of internal combustion engines and clean energy, in particular to a new type of mixed fuel for diesel engines and its application in diesel engines. Background technique [0002] Traditional diesel engines adopt compression ignition and spray diffusion combustion, which have high thermal efficiency, but the biggest challenge in the field of emission reduction is soot and NO x Emissions, the use of clean oxygen-containing alternative fuels is one of the effective means to achieve energy saving and emission reduction of diesel engines. [0003] N-pentanol is a new generation of biomass liquid fuel with good development prospects. Compared with low-carbon alcohol fuels methanol, ethanol and butanol, n-pentanol has a higher cetane number, which improves the ignition characteristics; calorific value Higher, higher energy density; lower latent heat of vaporization, improved engine cold start; viscosity close to petrochemi...
