CO, UBHC, NOx and Lead constitute the primary pollutants that cars contribute. Sound beneath water that is created in the atmosphere is less perceptible than the sound. This is mainly due to tiny water molecules sprockets, which reduce its amplitude, which lessens the loudness of the sound. This damaging nitrous and Sulphur content generated by the motor is filtered by the activated carbon layer. It converts high mass bubbles to low mass bubbles and lowers noise emissions. This silencer requires water and is hence called AQUA SILENCER. The aqua Silencer is used for noise reduction and management of harmful gas emissions in vehicles. Keywords— Pollution, Aqua silencer, Charcoal layer, Reduce noise I. INTRODUCTION Aqua Silencer has been amended to reduce hazardous emissions from the exhaust of an IC engine into the atmosphere by use of a traditional quilter. It includes the use, via simple but efficient changes in design and manufacturing of the silencer, of cheap chemical products such as lime water, activated charcoal and water. The exhaust pipe of the engine is installed to minimize the noise [1]. Underwater sound is less hearable than atmospheric sounds. It reduces the sound intensity largely because of the little sprockets in the water molecules [2]. The emission may be regulated by the activated layer of charcoal and is very porous. Thus, absorb gas from the engine and release it to the atmosphere considerably less. In addition to typical single-unit engine silencers put on industrial and heavy- duty motors, an aqua silencer system has been devised [3]. The sound and emission control in IC engines is employed. The sound generated can be decreased by utilizing water as a medium. It can also be employed in cars with additional development [4]. It has been identified as an excellent adsorbent for the current investigation using some inexpensive compounds. CO, CO2, etc. are the major pollutants. We need cheap and effective technology in developing countries like India [5]. Silencer is also known as muffler. It is used to reduce exhaust noise from an internal combustion engine that is an important cause of noise pollution. When utilized in residential areas or regions where noise presents a risk, it becomes a more important problem. Noise levels of well above 80-90 dB are often harmful to people [6]. The major source of noise in a motor is separated into two sections; firstly, there is the noise of exhaust, and secondly, the noise is caused by friction of many engine elements. The most dominating motor exhaust noise is.
