Modified Silencer and Air Intake System
Bhagwan Singh Vishwakarma of Bhopal invented to modify the silencer and air intake system. The present modification in silencer increased the mileage of the vehicle (especially two-wheeler with four strokes). Increment of the mileage happens due to proper combustion of the fuel. The main concept of this innovation is preheating of intake air so that complete combustion happens in engine. It claimed to increase the mileage up to 27 percent. Her novelty lies in design of silencer, which does not require any external power source for preheating the intake air continuously. It also reduces the noise level.
