Sound produced under water is less hearable than it produced in atmosphere. The other end of the perforated tube is closed by plug. The other end of the perforated tube is closed by plug.
The perforated tube has different diameters. Generally 4 sets of holes are drilled on the perforated tube. Around the circumference of the perforated tube pollution.
Literature Survey The control unit is given an electric supply of 12V. The Ruthenium sensor is then activated.
Now a signal is 1. Patel et. The exhaust gases now enter the water to reduce emission and noise level with the help of tub. Water tub reduces noise and toxins from gases get aqua silencer. According to them perforated tube dissolved.
Nanotubes are used for regeneration from which is installed at the end of pipe may have holes of hydrogen molecules. This silencer controls water and different diameter. The very purpose of providing air pollution, it also reduces unwanted vibrations when different diameter holes is to breakup gas mass to form the vehicle is in steady state. We have observed from various tests, the silencer. Prem Sankar R. So we can conclude that , aqua silencer is diesel engine to reduce the pollutants and noise level more efficient than conventional silencer.
They have fabricated and tested aqua silencer, they have used activated 4. And then aqua silencer without lime water is connected on the exhaust and determine the amount of exhaust gas by smoke analyser.
At last the silencer with lime water which is connected to exhaust pipe and readings are taken. The results which are obtained from the project analysis is given below in the tables. Smoke analyser 0tests were carried out for analysing the performance of the silencer.
Table 3 Test result using Simple Silencer Pollution Analyser test in single cylinder four stroke diesel engine Constituents. It can absorb some portions of the toxic gases present in the exhaust. During this test, it is found that the amount of hydrocarbons and nitrogen dioxide are reduced as compared to the previous test.
This is because of the reason that the charcoal embedded inside the silence has absorbed certain amount of the gas. The changes in the amount of other gases are negligible. Table 4 - Test result using Aqua Silencer Pollution Analyser test in single cylinder four stroke diesel engine with Aqua silencer Constituents. This test is found to be more efficient.
The amount of hydrocarbon has increased than that of the previous test. This is due to the reason that, while applying lime water the temperature will be decreased inside the silencer. High temperature is needed for the hydrocarbon to burn completely and this results in the incomplete combustion of the hydrocarbon. But it is found that the there is a considerable reduction in the amount of nitrogen dioxide.
As nitrogen dioxide is more toxic than hydrocarbons, this test is considered as more efficient. By using perforated tube the fuel consumption remains same as conventional system by using water as a medium the sound can be lowered and also by using activated charcoal in water we can control the exhaust emission to a greater level.
The water contamination is found to be negligible in aqua silencer. It is smokeless and pollution free emission equivalent to the conventional to the silencer. It can be also used both for two wheelers and four wheelers and also can be used in industries. The engine emission contains air pollutants and other species. Almost all pollutants are toxic in nature. Among the air pollutants, all are most effective pollutants.
Hence, the removal of pollutants was selected for the present study. Several expensive techniques are available in developed countries. But in developing countries like India is not applicable since adsorption technique is less expensive and economically feasible, it has been selected for the present study using some cheap cost chemicals as an effective adsorbent. Therefore the objective of the present work was to test the ability of some chemicals in removing air pollutants from engine emission.
In future researches are going on to develop an aqua silencer which can be fitted in to automobiles without effecting its aerodynamics properties and efficiency. Mathur, R.

They are as follows: Activated carbon pallets 7. Type - Air cooled No. Torque - 4. Start the engine easy. Control emission and noise in greater level. Carbon is precipitated.

Wiwit Climber. Generally 4 sets of holes are drilled on the perforated tube. The other end of the perforated tube is closed by plug. Around the circumference of the perforated tube a layer of activated charcoal is provided and further a metallic mesh covers it.
The whole unit is then placed in a water container. A small opening is provided at the Top of the container to remove the exhaust gases and a drain plug is provided at the bottom of the container for periodically cleaning of the container.
Also a filler plug is mounted at the top of the container. At the inlet of the exhaust pipe a non-return valve is provided which prevents the back flow of gases and water as well. As the exhaust gases enter in to the aqua silencer, the perforated tube converts high mass bubbles in lo low mass bubbles after that they passes through charcoal layer which again purify the gases.
It is highly porous and possess extra free valences so it has high absorption capacity. After passing over the charcoal layer some of the gases may dissolved into the water and finally the Exhaust gases escape through the opening in to the atmosphere.
Hence aqua silencer reduces noise and pollution. Following chemical reactions takes place in aqua silencer: Water will absorb the oxides of Nitrogen to a larger extent. The following chemical reaction will enhance the proof, for the above statement. If a small amount of limewater is added to scrubber tank, further reaction takes place as below.
When the carbon-di-oxide present in the exhaust gas comes in contact with the limewater, calcium carbonate will precipitate.
The calcium carbonate when further exposed to carbon-dioxide, calcium-bi-carbonate will be precipitated. The following is the chemical reaction,. The sulphur-di-oxide present in the Diesel Exhaust also reacts with the limewater. But the small trace of sulphur-di-oxide makes it little difficult to measure the magnitude of the chemical reaction, accurately.
The following equation gives the chemical reaction and calcium sulphite will precipitate. From calcium carbonate, calcium sulphite will precipitate and CO2 will be by-product. Because of the small percentage and SO2 presence, the liberation of Carbon dioxide is very less. The aqua silencer is more effective in the reduction of emission gases from the engine exhaust using perforated tube, lime water and charcoal by using perforated tube the back pressure will remain constant and the sound level is reduced.
By using perforated tube the fuel consumption remains same as conventional system by using water as a medium the sound can be lowered and also by using activated charcoal in water we can control the exhaust emission to a greater level.
The water contamination is found to be negligible in aqua silencer. It is smokeless and pollution free emission equivalent to the conventional to the silencer.
It can be also used both for two wheelers and four wheelers and also can be used in industries. Aqua Silencer Published on Jan 01,
