“…Rahman and Ramesh [53] observed that when increasing the biogas content from 24% to 68%, the ignition delay decreased and the speed of combustion increased, thus, in order to stabilize the two indicators, advancing the start of diesel injection by three crank angle degrees (CADs) was proposed. The operation of dual fuel at the injection timing of 26 CAD BTDC (Before Top Dead Center) rendered a better overall result than other injection times [54]. Biogas was observed to be able to significantly reduce diesel consumption, thus, the diesel replacement ratio ranged from 15% to 88% in the present compression ignition engines.…”

“…The more homogeneous the blend is, the more the values of particulate matter/smoke drops. On the other hand, HC and CO emissions increased due to varying reactivity of fuel components, also increasing NO x emissions, especially at low engine loads [4,6,49,52,54,55,58]. The use of biogas containing up to 73% methane yields a significant ecological effect on engine life from P. pinnata plant biomass.…”

The Article presents the results of the experimental research and numerical analysis of a compression ignition (CI) engine adapted for running on dual fuels of different composition (diesel and natural gas, diesel and biogas, biodiesel and natural gas, and biodiesel and biogas). The main goal was to find out the impact of different dual fuels on energy performance and emissions depending on the start of injection (SOI) of diesel and the crank angle degree (CAD). Pure conventional diesel fuel and second generation hydrotreated vegetable oil (HVO) (Neste) was used in the research. Natural gas contained 97 vol. % of methane. Biogas (biomethane) was simulated using a methane and carbon dioxide blend consisting of 60 vol. % of methane and 40 vol. % of carbon dioxide. Dual (liquid and gaseous) fuels were used in the tests, with the energy share of liquid fuels accounting for 40% and gas for 60%. The research results have shown that having replaced conventional diesel fuel with dual fuel, engine’s BTE declined by 11.9–16.5%. The use of methane in the dual fuel blend reduced CO2 volumetric fraction in the exhaust gases by 17–20%, while biomethane increased CO2 volumetric fraction by 10–14%. Dual fuel significantly increased CO and HC emissions, but NOx volumetric fraction decreased by 67–82% and smoke by 23–39%. The numerical analysis of the combustion process revealed changes in the ROHR (Rate of Heat Release) that affected engine efficiency and exhaust emissions was done by AVL (Anstalt für Verbrennungskraftmaschinen List) BOOST program.

“…A comparison of the biogas constituents obtained from the samples S 1 , S 2 , S 3 , S 4 and some of the commonly available feed stocks are given in Table 6 from Jatropha curcas, municipal solid waste and the CD were in the range of 60-68, 40-60 and 50-70 % [21,35]. The biogas obtained from sample S 3 had about 17 % CO 2 , which acted as an agent for the reduction of smoke and NO x emissions, when it was used in an SI (spark ignition), CI (compression ignition), HCCI (homogeneous charge compression ignition) and dual fuel engines [36][37][38][39][40].…”

“…Local pollutant emissions from the transportation sector can be decreased by the choice of fuel or by the use of different technologies. A drastic reduction in emission could be gained by using biogas as a fuel [40,41]. At this moment, it seems that the greatest reductions of GHG can be achieved, if the biogas is used as a transportation fuel.…”

In this study, experiments were conducted with four different proportions of seed cake of Karanja (SCK) and cattle dung (CD) mixture, for biogas production. 75, 50 and 25 % of the SCK on a mass basis were mixed with 25, 50 and 75 % of the CD and, named as S 1 , S 2 and S 3 . For comparison, biogas obtained from 100 % CD (S 4 ) was considered. The samples were kept in four different reactors, for 30 days of observation, and the yield of biogas from the samples S 1 , S 2 and S 3 was evaluated. Modeling was carried out for prediction and optimization of biogas production using ANN (artificial neural network) and the GA (genetic algorithm). A multi-layered feed-forward network with hidden neurons and linear output neurons was used for training the network using the input parameters pH, digestion time and C/N ratio for the yield of biogas. The performance of the neural network model was verified, and the correlation coefficients were found to be close to 1, for the samples. The experimental results on the biogas production were validated with the results of the neural network and optimized with the GA. The GA optimized values for pH, digestion time, and the C/N ratio of sample S 3 were found to be 6.68, 14.22 days and 24.1:1, respectively. These optimized data can be used to monitor a large scale anaerobic plant. Among all samples, S 3 gave a better result with respect to the pH, C/N (carbon/nitrogen) ratio, digestion time and biogas yield.

“…Recently, there have been some research undertaken about biogas application in dual-fuel engines (Barik, Murugan 2014;Barik, Murugan 2016;Bora, Saha 2016;Makareviciene et al 2013;Sorathia, Yadav 2012;Wei, Geng 2016). Most of those papers set limits to biogas composition ratios, enrich biogas with methane or refine it in order to increase methane share.…”

Limited fossil fuel supplies and the necessary reduction in toxic fumes emission to the atmosphere are the main motives in conducting a search for the new, effective energy supplies. The one with potential is biogas. It is the product of natural fermentation processes of municipal waste in landfills or is produced in biogas plants out of agricultural and green waste. Due to creation under different conditions, its chemical composition varies. This is enormous obstacle in its effective application. Biogas is easily applied to fuel spark-ignition engines however intensive attempts are made to employ it in much more effective compression-ignition engines. Application of biogas require the use of dual-fuel CI engine. The point of the research described in this paper is to show the influence of different methanecarbon dioxide composition ratio in biogas on dual-fuel CI engine effectiveness.
