This paper proposes a multi-stage power generation system suitable for renewable energy sources, which is composed of a DC-DC power converter and a three-phase inverter. The DC-DC power converter is a boost converter to convert the output voltage of the DC source into two voltage sources. The DC-DC converter has two switches operates like a continuous conduction mode. The input current of DC-DC...

The major pollutants emitted from spark ignition (SI) engine are carbon monoxide (CO) and unburnt hydrocarbons, nitrogen oxides which are hazardous to human beings and environment. If the engine is run with alcohol blended alternate fuels, aldehydes are emitted as significant pollutants, which are carcinogenic and harmful in nature. Hence, control of these aldehyde emissions call for immediate ...

Investigations were conducted to evaluate the performance of a two-stroke, single cylinder, spark ignition (SI) engine, with gasohol (80% gasoline and 20% ethanol by volume) having copper coated engine [CCE, copper-(thickness, 300 μ) coated on piston crown, inner side of cylinder head] provided with catalytic converter with different catalysts of sponge iron and manganese ore and compared with ...

The need to deliver fast-in-market and right-first-time ultra low emitting vehicles at a reasonable cost is driving the automotive industry to invest significant manpower in the computer-aided design and optimization of exhaust aftertreatment systems. To serve the above goals, an already developed engineering model for the three-way catalytic converter is linked with a genetic algorithm optimiz...
