Design of Portable Catalytic Converter with Temperature Control Based on Arduino for Waste Gas Diesel Engine

Catalityc converter is device that using of catalyst media.The media of catalyst is expected to accelerate the reaction rate at a certain temperature. In the process of combustion of fuel and air in addition to enthalpy, residual combustion products are emissions or pollutants of CO, CO2, NOx, HC, soot or smoke and other elements that can pollute the environment and can endanger human health. Diesel engines produce more soot and NOx gas pollutants than gasoline motors, but produce lower CO2. With the regulation of the temperature of the catalytic converter installed in the exhaust manifold system or diesel engine exhaust can reduce exhaust emissions in the form of black smoke or soot. The testing of this study used a quasi experimental method by comparing the exhaust gas data produced by diesel motors on the exhaust manifold system both those using and without catalytic converters. Data retrieval is carried out conditioned at room temperature during testing. The test starts at the rotation of the diesel engine 1500 RPM to 4000 RPM with an increase in rotation every 500 RPM. The overall results of using catalytic converters are very effective in reducing the density of the smoke or opacity of the diesel engine its was average of 18.69%
