Natural Decomposition

Biogas is the term used for the gas made from the natural decomposition of Organic (plant or animal) materials. It is Produced when the materials are digested by bacteria in a situation where little or no air is present (anaerobic digestion). Biogas consisting of approximately two-thirds methane (CH4) and one-third carbon dioxide (CO2) burns well and can be used to provide energy in the form of heat or electricity. The main practical sources of biogas are sewage, animal manure and the organic materials in household refuse or industrial waste. Like other renewable energy sources, biogas is a stored form of solar energy (since it originates from plants which used the sun’s energy to grow). An experimental evaluation was carried out to compare the performance of an IC engine (SI) Using Biogas as fuel blended with petrol in different proportions to that of only petrol as fuel. The performance study carried out in a four cylinder SI engine shows that this can better be used as an automotive fuel with a comparatively much lesser cost than the conventional fuels. The results show that because of the low calorific value of biogas the thermal efficiency is lesser than that of petrol and remains same at low and high out puts. Same is the case for volumetric efficiency. Biogas is an excellent and economical fuel for both petrol and diesel engines. However the power obtained is less than that of liquid fuel. Biogas is a cheaper and better fuel for cooking, lighting and running engines.

Basic Movement

Improving the reliability of structures of transport mechanisms and other elements, reducing metal content, improving performance, expanding functionality and technical capabilities is a priority area of work to improve existing and develop new machines for beet growing. The dynamic model of the chain conveyor which considers the basic movement and fluctuations of elements of the drive and a working cloth is developed in work. The model is represented by a system of discrete masses with eight degrees of freedom. The operation of chain conveyors is characterized by the presence of dynamic forces arising from the pulsating movement of the chain at a steady rotation of the drive sprocket. At the start-up site, dynamic forces from increasing the speed from zero to a certain constant value are added to these forces. Under such conditions, significant alternating dynamic loads can occur in the chain, which as a result of the accumulation of fatigue phenomena can lead to its premature destruction.

Si Engines

The use of alternative fuels such as methanol and ethanol in spark-ignition (SI) engines is beneficial to the environment as it reduces emissions of pollutants such as NOx from these engines with slight penalty on the performance. This paper investigated the use of liquid fuel blends such as ethanol/gasoline blend in an SI engine by numerical simulations. The numerical simulations were based on the models of finite heat release, cylinder heat transfer, pumping losses, and friction losses. Simulations were carried out to evaluate the effects of compression ratio, equivalence ratio, ignition timing, and engine speed on the performance of the SI engine. The results of the simulations were compared with experimental data from the literature to validate the simulations. Good agreements between the computed and experimental results were obtained. The results showed that the current model could satisfactorily predict the performance of an SI engine fueled by liquid fuel blends.
