    Abstract:

    Alcohol, as an alternative Fuel, has attracted the attention of many companies and researchers worldwide. In fact, several studies have looked into emission and performance characteristics of alcohol used in compression-ignition (CI) engines. Fusel oil is an Alcohol-Based Fuel collected as a by-product from the fermentation of alcohol. Hence, this experimental study compared fusel oil–diesel blended Fuel F20 (20% vol fusel oil and 80% vol diesel) with pure diesel in a single cylinder four-stroke CI engine. The test was performed at two engine loads (50% and 75%) and five engine speeds (from 1200_2400 rpm with intervals of 300 rpm). In fact, the main goal of the current study was to determine engine power, torque, indicated specific Fuel consumptions, in-cylinder temperature, energy release rate, cumulative energy release, and emissions (carbon dioxide, CO2; carbon monoxide, CO; and nitrogen oxide, NOx) with F20, as well as in comparison with diesel. The results revealed that the engine power and the torque for F20 slightly dropped compared to those with pure diesel. Moreover, the indicated specific Fuel consumption (ISFC) was slightly increased, especially with 75% load at high engine speeds and at around 8% at an average, while the ignition delay for F20 had been longer by 7% at all engine speeds and loads compared to those with diesel. Furthermore, a reduction in nitrogen oxide (NOx) emissions was observed at all engine loads and speeds, while the highest reduction in NOx for F20 was 28% with 1500 rpm at both loads. In addition, it was found that both CO2 and CO emissions increased. Nevertheless, high water content, low cetane number, and low heating value of fusel oil had been the reasons for the negative effect displayed upon the performance of the engine.

  • The low-temperature corrosion characteristics of Alcohol-Based Fuel combustion
    RSC Advances, 2018
    Co-Authors: Zhiqiang Wang, Xingxing Cheng
    Abstract:

    In this paper, the low-temperature corrosion characteristics of the four Fuel combustions that include methanol, diesel, MF75 (the volume fraction of methanol is 75 ± 2%), and MF50 (the volume fraction of methanol is 50 ± 2%) were studied. MF75 and MF50 were modulated by methanol, diesel and a small amount of cosolvent. The quality indicators of four Fuels were judged by the specific standard. The acid dew point temperature of the four kinds of Fuel combustion flue gas was calculated and compared, and the acid ion in the condensate of the four Fuel combustion products was analyzed and tested. Based on this method, the corrosiveness of four kinds of condensate was determined. The corrosion rates of five metals (brass, 304 stainless steel, 316 stainless steel, corten steel, and Q245 steel) were tested by two different methods (electrochemistry corrosion and static immersion corrosion). The experimental results show that the quality indicators of four Fuels have all reached the relevant national standards. The dew point temperature of methanol, MF75 and MF50 are lower than that of diesel. The corrosion products on the surface of corten steel are relatively compact and easily accumulate dust, which is not conducive to the safe operation of the boiler. The corrosion resistance properties of 316 stainless steel is excellent, showing that it would be the ideal material choice for the low-temperature zone of a boiler flue.
