Experimental investigation on emission and performance charcterstics of a catalytic coated four stroke ic engine

Abstract

Every person in this world needs private vehicles for their domestic purpose. The automobile industries are implementing modern techniques to improve engine efficiency and reduce emission norms. Government is trying to reduce the emission levels due to global warming issue and customers are purchasing fuel efficient vehicles. So modifications on IC engine operated vehicles like improved aerodynamics, using catalytic converters, bio-fuels usage, weight reduction and hybrid power trains are being implemented by the industry. This leads to reduce emission and improved performance of IC engine operated vehicles. newlineIC engine is the one of the main power source for automotive vehicles. In the current scenario IC engine technology is used all type of automotive vehicles because of its ease maintenance, long run operations and affordable cost. The engine produces power with help burning the fuel. Due to burning of fuel or combustion the engine produces various toxin gases like carbon monoxide (CO) and hydrocarbon (HC) and oxides of nitrogen (NOx). It leads to pollute the environment and increases the effect of global warming, climatic change and health issues problems. Automotive pollution is considered to be the main reason for environment pollution. Specifically, IC engine pollution plays a major role in producing toxic gases into the environment. Incomplete combustion is one of the reasons for the emission of harmful gases like carbon monoxide (CO), un-burnt hydrocarbon (UHC), oxides of nitrogen (NOx). So, combustion efficiency has to be increased in order to reduce the emission levels in the exhaust. newline
