“…However, due to their high thermal efficiency and small size, diesel engines have found a wide range of applications [4][5][6]. Alternative fuels are being sought to reduce emissions of harmful components from exhaust gases [7][8][9][10][11][12][13]. In response to the depletion of natural energy resources and an increase in CO 2 emissions resulting from the combustion of fossil fuels, research on biomass fuel production is carried out worldwide [14][15][16][17][18][19][20][21][22][23].…”

The aim of this study was to perform a comparative analysis of the unit gas emission value in the exhaust of a dual fuel diesel engine. The results of the effects of a diesel engine’s applications in biogas plants and the method for calculating mass gas emissions per unit of produced electricity are shown. The test was performed using a two-cylinder, naturally aspirated, liquid-cooled diesel engine. The diesel engine powered a generator connected to the grid. The engine was fed with liquid fuels—waste cooking oil methyl ester (UCOME) and diesel fuel (DF)—and with a gas fuel, biogas (BG). The engine ran at a constant rotational speed (2000 rpm ± 30 rpm) with variable load. The gas analyzer measured the amount of CO, NO, NO2, and PM (particulate matter) in exhaust gas. This gas content share was then converted to mass per engine generated energy unit. This experiment showed the effect of BG introduced to the intake manifold on fuel combustion, as well as an increase in CO and NO2 emission and decrease in NO and PM. In terms of dependence of exhaust emissions on the type of liquid fuel used, the use of UCOME as opposed to diesel fuel resulted in PM reduction and increase of NO emissions.

Butanol is considered as the more promising alternative fuel candidate because of its favorable chemical and physical properties over ethanol and methanol. In this study, the performance and emissions of a port fuel injected spark ignition engine fueled with butanol‐gasoline blends (0–60 vol % butanol blended with gasoline referred as G100‐B60), including brake thermal efficiency (BTE), brake specific fuel consumption (BSFC) and carbon monoxide (CO), unburned hydrocarbon (UHC), nitrogen oxide (NOx), were investigated under various equivalence ratio. Among the butanol‐gasoline blends, B30 performs well in engine performance and emissions due to its CO (2.3%–8.7%), UHC (12.4%–27.5%), and NOx (2.8%–19.6%) emissions compared to those of gasoline. Butanol can be a good alternative fuel to gasoline for its potential to reduce pollutant emissions. It is well known that engine tests are hard, time consuming, and high cost. Therefore, support vector regression (SVR) was used to predict the performance and emissions of the engine, where equivalence ratio and blend ratio were used as the input parameters, and BTE, BSFC, CO, UHC, and NOx were used as the output parameters. It was observed that the correlation coefficients and mean relative error were in the range of 0.9940–0.9998 and 0.1901–10.2570%, respectively. The SVR predictions of BTE, BSFC, CO, UHC, and NOx yielded the root‐mean‐squared‐errors of 0.0511%, 4.6058 g/kW h, 0.9995% vol, 7.7503 ppm vol and 38.5861 ppm, respectively. It could be indicated that the SVR provided an accurate and simple approach to analyze performance and exhaust emissions of spark ignition engine. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13042, 2019

Blade icing can affect wind turbines to generate electricity. In severe cases, 30% of power generation is lost in a year, and safety problems in the vicinity of wind power plants are also caused. Researchers have designed anti-icing and de-icing technologies to reduce these effects, and excellent ice-detecting devices are a prerequisite for using anti-icing and de-icing technologies. Ultrasonic attenuation technology can effectively and reliably detect the presence of ice without affecting the aerodynamic performance of the blade, providing a reliable guarantee for anti-icing and de-icing systems. Deicing and anti-icing systems are divided into active and passive, active heating blades are still the most effective anti-icing and de-icing methods, but their energy consumption is too high. Although there are many existing de-icing methods, there are not many practical uses. This article introduces them separately and lists their advantages and disadvantages. The use of ultrasonic anti-icing and de-icing is an economical and reliable means that has been proven to be used for anti-icing and de-icing of blades. However, under normal circumstances, a single anti-icing de-icing system cannot completely solve the problem of icing of the blades. This paper suggests using both ultrasonic and hydrophobic coatings to cope with more icing conditions.

Owing to release a lot of greenhouse gases, chemicals and toxins substances from the combustion of the fossil fuels such as coal and oil, 1 People began to look for renewable energy to provide energy consumption, such as wind energy, 2-4 hydrogen energy, 5-7 solar energy, 8-10 biogas and biomass energy. 11-15 With the wind power growing rapidly, generate electricity by using wind turbines is economical and environmentally friendly. 16 As can be seen in Figure 1, China's total installed capacity of wind turbines in 2016 is much higher than in other countries.China has the largest wind power market in the country, and the installed capacity of wind power is growing steadily year by year. The high density of air is conducive to the development of wind energy resources in cold regions. Figure 2 shows wind resource changes in different seasons. The wind speed from June to August is significantly lower than other months. There are also data showing that wind resources in cold regions are 10% higher than other regions. 17,18
