SYNOPSIS

INTRODUCTION

Diesel engines are playing a vital role in Road and sea transport, Agriculture, mining and many other industries. Considering the available fuel resources and the present technological development, Diesel fuel is evidently indispensable. In general, the consumption of fuel is an index for finding out the economic strength of any country.
In spite, we cannot ignore the harmful effects of the large mass of the burnt gases, which erodes the purity of our environment everyday. It is especially so, inmost developed countries like USA and EUROPE. While, constant research is going on to reduce the toxic content of diesel exhaust, the diesel power packs find the ever increasing applications and demand.

This project is an attempt to reduce the toxic content of diesel exhaust, before it is emitted to the atmosphere. This system can be safely used for diesel power packs which could be used in inflammable atmospheres, such as refineries, chemicals processing industries, open cost mines and other confined areas, which demands the need for diesel power packs.
For achieving this toxic gases are to be reduced to acceptable limits before they are emitted out of this atmosphere, which otherwise will be
hazardous and prone to accidents.

MEASUREMENT OF EXHAUST GAS CONTENT ANALYSIS AND CONTROL

For measuring the contents of the exhaust gas, provisions are made to take samples between engine outlet and scrubber inlet and after the scrubber outlet before the gases are let-out to the atmosphere. These sampling points enable us to measure the exhaust gas content before and after scrubbing. The difference is evaluated and effective control is initiated. The samples are analyzed by using an orsat apparatus of the system.

WORKING PRINCIPLE

The aqua silencer is more effective in the reduction of emission gases from the engine exhaust gas using water and lime stone mixture. By using water and lime stone mixture the back pressure will remain constant and the sound level is reduced. Using the 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 limestone in water we can control the exhaust emission to a greater level. The water contamination is found to be negligible in aqua silencer, because the amount of acidity level in aqua silencer is expected to be below the dangerous acidity. It is smokeless and pollution free emission and also very cheap. The aqua silencer’s performance is almost equivalent to the conventional silencer.

ADVANTAGES AND DISADVANTAGE

ADVANTAGES

Diesel engines are playing a vital role in Road and sea transport, Agriculture, mining and many other industries.

In general, the consumption of fuel is an index for finding out the economic strength of any country.

DISADVANTAGE

Need to alter the silencer which may increase the total weight of the vehicle.

CONCLUSION

The aqua silencer is more effective in the reduction of emission gases from the engine exhaust gas using perforated tube. 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 grater level. The water contamination is found to be negligible in aqua silencer, because the amount of acidity level in aqua silencer is expected to be below the dangerous acidity. i.e. 250mg/lit. It is smokeless and pollution free emission and also very cheap. The aqua silencer’s performance is almost equivalent to the conventional silencer.
In No load condition, by using AQUA Silencer the NOx will be reduced to 29.9%, the Particulate Matter will be reduced to 70%. In the Smoke Density will be reduced to 67.36%.
