The improvement of flow strategy is implemented in the intake system of the engine to produce better biogas engine performance. The intake system for air-fuel mixture is studied, designed, simulated and analyzed with ANSYS-CFX and CFD-Post code. The components: the venturi and its outer body are installed to produce pressurized turbulent flow with higher fuel volume in the intake system, which is ideal condition for biogas fuelled engine. A venturi-inlet holes mixer with three variables: number of inlet holes (4, 8 and 16); hole diameter (3, 2 and 1.5 mm) and the inlet angles (300 , 250 and 200 ) are studied. In this study it is found that the combination of throat diameter 17.24 mm, convergent angle 300 , hole diameter 3 mm and number of holes 4 is proven to improve the power output 11.5% and torque 15.5% compared to average values of the same with other combinations. However, this figure, still approximately 15% lower compared to that of gasoline mode.

Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
