Abstract – This research study aims to control the emission
are small sprockets are present in water molecules which helps to reduce the asperity of noise. The perforated tube and charcoal layer is also provided inside the silencer. The charcoal layer installed in this silencer helps to control the emission. This charcoal layer sieves the harmful sulphur and nitrous contents coming out from the engine therefore there is no necessity of catalytic converter. In the regular silencer catalytic converter is used for emission control but this silencer is replaced by aqua silencer with minimum cost and good performance.
and noise reduction of engine by inventing aqua silencer at its exhaust. The regular silencer is used for noise reduction and emission control, but; aqua silencer technique is invented in regular silencer to reduce the noise and emission control at great level. Silencer collects the exhaust of engine; reduce its noise and delivers to the atmosphere. While reducing the noise level of engine backpressure should be minimum; this effects on its efficiency. This silencer contains water which helps not only for noise reduction but also control of emission. The aqua silencer is designed by referring the various research papers and test results are calculated.
2. LITERATURE REVIEW Mr. Sachin S. Morti et. al. (2021) have researched on backpressure investigation and design modification to reduce noise level of silencer used for single cylinder water cooled diesel engine through CFD simulation. In this research study, silencer design is modified by using CFD simulation software as a tool for numerical analysis. The comparison between regular silencer and modified silencer is made and results are tabulated with the help of CFD simulation. The modified design of silencer is enormously efficient in noise reduction of engine than regular silencer. The backpressure of modified design of silencer is also minimum as compared to regular silencer, which increases engine efficiency. The perforated baffle plate is installed inside the silencer to control the acoustic pulses generated by engine.
Key Words:
Aqua Silencer, emission control, noise reduction, backpressure.
1. INTRODUCTION The automobile engine should be always equipped with silencer to attenuate the acoustic pulses generated by the engine. The noise is generated because of pressure difference between exhaust of engine and atmosphere. This pressure difference can be bridged by inventing silencer at the exhaust of automotive engine. The invention of silencer at the exhaust of engine helps to reduce the noise level as well as controls the emission. Environment pollution is the major problem in the world. The air pollution sources are automobiles, thermal power stations, industrial processing, refuse burning etc. These pollutants are hazardous for environment as well as human beings. The polluting agents at the automobile exhaust are carbon-monoxide (CO), Carbon-dioxide (CO2), Un-burnt Hydro Carbon (UBHC), Sulphur-dioxide (SO2), Oxides of Nitrogen (NOX) and Lead etc. The pollution should be controlled for the preservation of living organisms. The aqua silencer can be used for the reduction of noise level and controlling the pollution.
Mr. Sachin S. Morti et. al. (2021) have reviewed on design modification to reduce the noise level of silencer used for single cylinder water cooled diesel engine. This review aims to design modification of silencer for noise reduction of engine with minimum backpressure. The reviewer has referred various international journals for studying different kinds of numerical methods used for shape modification of silencer. The CFD simulation and virtual lab software can be used for design modification of silencer. In this review study various methods such as CFD simulation software, virtual lab software, acoustic software, various geometrical types of exhaust multifarious and their consequence on the pastime of engine have collected and discussed.
The aqua silencer is fabricated with less cost as well as easily for installation. This silencer is installed at the exhaust of the engine. The aqua silencer is very effective for the controlling pollution and reducing the noise level as compared with regular silencer; because noise produced inside the water is less audible as compared to noise in free atmosphere.
