Inspired by a car maker’s goal to create less carbon emission from an engine, five students of Swami Vivekananda Institute of Technology (SVIT) have attempted to do the same and have succeeded.

As a part of their final year project, Shiva Shanker, Rakesh Palakurthi, Dinesh Reddy, Mahesh Goud and Mohan Kumar, all from mechanical branch worked on their project that aims at enhancing the efficiency of petrol engine.

Their idea of introducing Brown’s gas through electrolysis into the vacuum hose of the car has helped increase mileage by 40 per cent.

The apparatus used to generate the gas is sent into the hose where air-fuel mixture is burnt. “When the gas is sent in, the energy released through the mixture of the gas and petrol is more and there by mechanical energy is more,” says Rakesh.

It took three months for the team to come up with a working model of the project. “When the project was being made, we tested the concept on a one KW generator-cum-engine. It was run on petrol first and the readings were taken down. Then we introduced Brown’s gas into the engine and the emissions were cut down drastically,” adds Shanker.

With the dry run being a success, the team decided to test the apparatus on a four wheeler.

“We placed the jars with electrodes and distilled water and connected it to the vacuum hose of the car.

The mileage jumped from 10 km per litre to 14 km per litre. We also noted that the petrol used was less and the carbon emission was even lower,” says Rakesh. “We knew that the gas was used in welding different materials. But the idea of this project was to tap the inherent energy of Brown’s gas and use it in a new way,” adds Rakesh.
