Detail:

The innovation is a modification in silencer of the two wheelers where part of the exhaust gas is used to pre-heat the air and charge leading to increased combustion efficiency of the engine. It results in the increase in the mileage by 25 to 30 per cent. The system is mainly a heat exchanger consisting of exhaust line, a nozzle for exhaust gas, heat exchanging chamber (between intake air and exhaust gas), modified air intake line passing through the heat exchanging chamber, ,an additional chamber, and aluminum covers. The exhaust gas enters the heat exchanger through the nozzle attached to the main exhaust line and supplies the exhaust gases from the same pipe to the heat exchanging chamber. One end of the modified intake air line is kept between the engine fins so that it gets fresh air easily and the other end of the pipes is connected with the filter. This line is made of copper. The additional chamber is situated behind the main chamber is connected with smoke outlet nozzle on the other side. Its purpose is to reduce the noise level. The aluminium covers are provided at both the sides of main chamber and make the device cool from the outside. In this system[i], the intake air is passed over the exhaust manifold (silencer), which results pre heating of the intake air. NIF facilitated its testing at BIT Mesra, Ranchi. The test report mentions that the use of the modified silencer and the system for preheating of intake air increases the mileage by 25 to 30 per cent. This technology is still in the process of being refined so that it can be used at a wide scale and needs some adjustments in filter, intake manifold and the timing of fuel supply. NIF also filed a patent (1460/MUM/2009) in his name for the technology.
