Abstract<\/strong><\/p>\n\n\n\n

         This paper presentsresults of research on developing biogas application technology for power generation, for producing mechanical energy for working machine and for transport in rural areas. Technology was completed based on theoretical research, modeling, and experimental results on 100 engines application. Two modes of biogas supply have been studied: on-site biogas and compressed biogas. Different solutions of conversion of traditional engine into biogas engine were studied. Dual fuel biogas-diesel engine is convenience for using alternative fuel but biogas spark ignition engine is more beneficial economically.
          The resultsshow that dual fuel biogas-diesel engine converted from diesel engine can produce equivalent maximum power as original diesel engine. But biogas engine converted from stationary gasoline engine produces about 20% power lower. Poor biogas fuel is not suitable for the engine running at speeds over than 2500 rpm. Biogas engine consumes about 1m3<\/sup> biogas to produce 1kWh electricity, saving 0.4 liters of diesel and contribute to reducing 1 kg of CO2<\/sub> emissions into the atmosphere.

Abstract<\/strong><\/p>\n\n\n\n

           This paperpresents the results of theoretical and experimental study of effects of engine operating parameters and fuel composition to performance of spark ignition engine converted from diesel ZH1115 engine. When converting to biogas engine, engine compression ratio is reduced to 14, 12 and 10. Combustion process in engine is simulated by FLUENT software. The experiment was conducted with a hydraulic dynamometer Froude. Biogas fuel is adjusted to different CH4<\/sub> composition.
         The simulation resultsfitted well with experiment data. Optimal compression ratio of engine running with biogas is e=12.With this compression ratio, power of biogas engine can reach to maximum power of diesel engine at speed of 2200 rpm. Optimum advanced ignition angle of the engine when running with biogas is varied from 34\u00b0to 42\u00b0before TDC. Within nominal speed region, engine power increases an average of 15% when CH4<\/sub> component in biogas increased from 60% to 87%.

Abstract<\/strong><\/p>\n\n\n\n

            Structure of traditionalengines is conserved while they are converted to biogas engines so that they can reuse petroleum as fuel when needed as before the conversion. In this case the detonation problem should be treated. The present paper simulate the effects of compression ratio of the engines to combustion of biogas fuel containing different CH4<\/sub> concentration. The results show that the compression ratio strongly influence on the pressure at the end of combustion but it presents a little effect on final combustion temperature and on heat release curves. With a given compression ratio of 12, the temperature and pressure at the end of combustion in engine decrease respectively 473K and 2 MPa when the mol concentration of CO2<\/sub> in the fuel increases from 20% to 40%.<\/p>\n\n\n\n

Abstract<\/strong><\/p>\n\n\n\n

                    The present paper presents some results of studying of combustion in combustion chamber of spark ignition engine fueled with biogas with 60% to 80% CH4 <\/sub>mol fraction contained in cylinders at 50 bars pressure.
The simulation of biogas combustion in engine is based on fluid dynamic software FLUENT with turbulence model k-e and partial premixed combustion model in which laminar flame speed is determined by different concentrations of fuel contained CH4<\/sub> and CO2<\/sub>.
                   The results show that when the engine fueled with 80% volume fraction of methane biogas, the optimal advanced ignition angle is in range of 20 to 36 degrees when engine speed varies from 3000rpm to 9000rpm and maximal powers at different engine speeds are lower than that of gasoline case about 20%.<\/p>\n\n\n\n

Abstract<\/strong><\/p>\n\n\n\n

              The experimentwas carried out on-site with biogas-diesel dual engine converted from Vikyno EV2400 diesel engine and Froude dynamometer. CH4<\/sub> concentration in biogas is adjusted from 65% to 91%.
The resultsshow that at speed of 1400 rpm, maximum power of biogas-diesel dual fuel engine becomes higher than that of diesel engine while CH4<\/sub> component in biogas greater than 85%. When engine speed increases, dual fuel  engine\u2019s maximum power exceeds diesel\u2019s one with poorer biogas. When engine speed is greater than 1800 rpm, maximum power of biogas-diesel dual fuel engine is higher than diesel engine\u2019s one with CH4<\/sub> concentration in biogas about 50% -60%. This result shows that at nominal regime, we can use poor biogas without CO2<\/sub> filter to obtainthe equivalent maximum power of dual fuel engine as diesel engine.
             The efficiency of dualfuel engine is reduced when it runs on low load regimes. Experimental results show that at 100% throttle opening, diesel consumption rate of dual fuel engine varies from 12.5% (at low speed) up to 15.5% (at high speed ), while the throttle opening is 70%, this rate ranged from 15% to 19%.

Abstract<\/strong><\/p>\n\n\n\n

             This paper presentsresults of research on developing biogas application technology for power generation, for producing mechanical energy for working machine and for transport in rural areas. Technology was completed based on theoretical research, modeling, and experimental results on 100 engines application. Two modes of biogas supply have been studied: on-site biogas and compressed biogas. Different solutions of conversion of traditional engine into biogas engine were studied. Dual fuel biogas-diesel engine is convenience for using alternative fuel but biogas spark ignition engine is more beneficial economically.
              The resultsshow that dual fuel biogas-diesel engine converted from diesel engine can produce equivalent maximum power as original diesel engine. But biogas engine converted from stationary gasoline engine produces about 20% power lower. Poor biogas fuel is not suitable for the engine running at speeds over than 2500 rpm. Biogas engine consumes about 1m3<\/sup> biogas to produce 1kWh electricity, saving 0.4 liters of diesel and contribute to reducing 1 kg of CO2<\/sub> emissions into the atmosphere.

Abstract<\/strong><\/p>\n\n\n\n

                The paper presents results of experimental study of performance of biogas spark ignition engine converted from Toyota 3Y automobile engine. The experiment was conducted on-site at biogas production plant with Froude hydraulic dynamometer. The results show that the maximum speed of the engine decreases when conversion a gasoline vehicle engine into stationary engine running on biogas. This maximum speed reduction is higher with lower CH4<\/sub> concentration in biogas fuel. Biogas engine power at nominal speed position after conversion is reduced from 20% (for rich biogas) to 30% (for poor biogas) in comparison to gasoline power at the corresponding speed.
                As CH4<\/sub> concentration in biogas increases from 60% to 78%, the maximum engine power increases by 8%. If supplying biogas to engine by simple carburetor, its power can be reduced to 30% in comparison with the case of using GATEC 21 biogas supplying kit with biogas flow adjustment. Increasing of advanced ignition angle according to engine speed is needed to improve the performance of biogas spark ignition engine.
