Abstract
The original biomass fast pyrolysis fuel was modified by an emulsification method to obtain emulsified biomass fast pyrolysis fuel with different proportions (the content of biomass fast pyrolysis fuel in the emulsified biomass fuel was 5 wt.%, 10 wt.%, and 20 wt.%, respectively). Taking commercial 0# diesel as the blank fuel, the friction and wear characteristics of tribo-pair material from an actual piston ring–cylinder liner lubricated by the varied fuels were investigated on a reciprocating friction and wear tester, respectively. The results showed that the friction coefficient and wear of tribo-pair material lubricated with emulsified biomass fuel increased with the biomass fuel content. In the case of 5 wt.% emulsified biomass fuel, the friction coefficient was smaller than 0# diesel, and the wear was not different from 0# diesel. At the same time, the friction coefficient and wear of 5 wt.% emulsified biomass fuel increased with the reciprocating frequency when the load was constant, while they increased with the load when the reciprocating frequency was constant.
Highlights
With the depletion of petrochemical energy, biomass fuel has a wide application prospect as a renewable new energy fuel, the quality of current biomass fuel cannot be compared with traditional fossil fuels
It is necessary to improve the quality of original biomass fuel in order to be better used as fuel oil in traditional power output equipment such as internal combustion engines [1]
The results showed that the corrosivity, calorific value, and cetane number of biomass fuel oil were improved after emulsification
Summary
With the depletion of petrochemical energy, biomass fuel has a wide application prospect as a renewable new energy fuel, the quality of current biomass fuel cannot be compared with traditional fossil fuels. Due to the high oxygen content, low cetane number, and high acid value of biomass fuel, it has low calorific value and strong corrosivity, and cannot be directly applied to internal combustion engines [2] It can be applied only after physical and chemical modification, including blending with commercial diesel fuel. The results showed that the emulsified fuel with 15% biomass fuel volume fraction had an obvious fuel-saving effect than 0# diesel fuel, and the maximum fuel saving rate could reach 10% Both NO and CO emissions were better than those of pure diesel. The fuel dilution of the engine oil had minimal effect on friction because the test conditions were under the boundary lubrication regime, significant effects were observed on wear in many cases. The lubrication characteristics of emulsified mixed oil (or emulsified biomass fuel) of biomass fuel and diesel with different ratios (5 wt.%, 10 wt.%, and 20 wt.%) were discussed, which was expected to provide basic data for the future application of the biomass fuel in engines
