Impact of Biogas and Waste Fats Methyl Esters on NO, NO2, CO, and PM Emission by Dual Fuel Diesel Engine

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.

“…The first method is using exhaust gas after-treatment techniques and the second method is using fuel additives [2][3][4]. The first method reduces the exhaust emission but unaffected the improvement in the performance of a diesel engine whereas the later one decreases the exhaust emission by simultaneously improving the performance of a diesel engine [5][6][7]. Nowadays there is extensive research focused on the development of water diesel emulsion as an alternative fuel due to their enormous advantages of adding water to diesel fuel [8].…”

The present study investigates the performance and emission characteristics of single cylinder VCR diesel engine fuelled with nano additive blended diesel emulsion and the results are compared with neat diesel. The nano additives used for present investigation is AL 2 O 3 and CeO 2 nanoparticles. The base fuels taken for the experimental work is diesel, water and surfactants (span 80 and Tween 80). The test fuels were prepared by using an ultrasonicator with emulsion technique. The nano additives added for the test fuel is in the ratio of 50 ppm (25ppm AL 2 O and 25ppm CeO 2 ) and 100 ppm (50ppm AL 2 O 3 and 50 ppm CeO 2 ). The entire investigation is conducted under constant speed and different load conditions. A substantial improvement in performance and a reduction in the exhaust emissions for the nano additive blended fuels compared to neat diesel were observed from the experimental results. For D88S2W10CA100 blend, optimum performance (BTH and BSFC) and emission (CO, NO x , UBHC and CO 2 ) improvement were achieved as compared to other test fuels.

“…They also reported that although a higher engine speed generated more noise, substituting the conventional diesel fuel (D100) with the biodiesel fuels lowered the sound pressure level of the engine, up to 0.7 dB(A), when the hydrogen gas was mixed with the intake air. The reduction amount varied, as it is strongly dependent on combustion characteristics of each blend, such as ignition delay, peak pressure level, and pressure gradient inside the cylinders [76][77][78].…”

Performance Enhancement of Internal Combustion Engines through Vibration Control: State of the Art and Challenges

et al. 2019

View full text Add to dashboard Cite

Internal combustion engines (ICEs) are the primary source of power generation in today’s driving vehicles. They convert the chemical energy of the fuel into the mechanical energy which is used to drive the vehicle. In this process of energy conversion, several parameters cause the engine to vibrate, which significantly deteriorate the efficiency and service life of the engine. The present study aims to gather all the recent works conducted to reduce and isolate engine vibration, before transmitting to other vehicle parts such as drive shafts and chassis. For this purpose, a background history of the ICEs, as well as the parameters associated with their vibration, will be introduced. The body of the paper is divided into three main parts: First, a brief summary of the vibration theory in fault detection of ICEs is provided. Then, vibration reduction using various mechanisms and engine modifications is reviewed. Next, the effect of using different biofuels and fuel additives, such as alcohols and hydrogen, is discussed. Finally, the paper ends with a conclusion, summarizing the most recent methods and approaches that studied the vibration and noise in the ICEs.
