WATER BATH TREATMENT OF EXHAUST GASES IN DIESEL ENGINE

Nowadays the main reasons for global warming are increasing: rapid industrialization, automobiles and deforestation. Though there are different methods to reduce the pollution in the diesel engine of the automobiles it is not possible to reduce the pollution up to 40% to 50% from diesel engine which operates at different loads. However in our project at the 1st stage itself the pollution has been reduced to 45% but now fixing addition two devices the emission is reduced nearly 70% in diesel engine.

in this project the emission characteristics were studied on four stroke diesel engine., Exhaust emission such as hydrocarbon, carbon monoxide etc smoke level were measured by passing the exhaust gases through the device there is considerable decrease in all the pollutants.

It consists of three stages:

Water Injection :
High pressure water is injected on the exhaust stream of exhaust gases. To increase the contact between gas and the water, water is injected on the flat plate by using the injector.

Water Bath:
The exhaust gases from the 1st stage is passed to the tank which consist of water. From the bottom the gas is passed and it is taken from the top. The heavier unburnt particle is settled down at the bottom of the tank.

Filtration:
The exhaust gases from the 2nd stage is passed to the filtration unit which consist of series of filter to remove the remaining dust particles and water droplets.

We took the exhaust reading in a diesel engine before and after fixing our device, there was a huge difference.
