Internal Combustion Engine

The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar four-stroke and two-stroke piston engines  Types of Engines 1.Internal Combustion Engine (I.C Engine):   in internal combustion engine the combustion take place inside the engine cylinder for example the auto mobile engine 1.External Combustion Engine:   In external Combustion engine the combustion take place outside the engine for example steam engine. Classification of I.C Engine by Fuel:- 1.Petrol Engine:-   In Petrol Engine petrol is used as a fuel. 2. Diesel Engine:-  In Diesel Engine Diesel is used as a fuel. Classification of I.C Engine by Ignition:- 1.Spark Ignition Engine:-  In Spark Ignition engine the combustion of


F LinkedI Reddit Delicious LinkedIn Reddit Delicious Technorati Technorati Biomass has been a major source, prior to the discovery of fossil fuel like coal and petroleum. Even through its role is presently diminished in developed countries it is still used widely in rural communities of developing countries there are five accepted technologies for converting biomass fuel into electrical energy Conventional steam cycle Gasification Pyrolysis Anaerobic digestion Landfill gas  Conventional steam cycle:- Biomass is burned to produce steam which is then used to derive turbine Gasification:- Biomass is converted into gas using a high temperature oxygen started environment Pyrolysis:- biomass in converted into liquid rather than a gas Anaerobic digestion:- typical sewage sludge is digested to produce methane Landfill gas:- collection of gas from landfill sites


Renewable energy technology are essential contribute to sustainable energy as they contribute to world energy security by reducing dependence on fossil fuel resources and providing opportunities for mitigating green house gases . the three generation of renewable technologies, reaching back more than 100 years are first generation technologies includes hydro power , biomass combustion and geothermal power and heat Second generation technology includes solar heating and cooling , wind power, modern forms of bio energy and solar photovoltaic Third generation technology includes advanced biomass gasification , enhanced geothermal system and marine energy first and second generation technology have entered the markets, third generation technology are not yet commercialized . they may have potential comparable to other renewable energy technologies.
