Looking at the rising fuel prices, people are in search of various means that help in reducing fuel cost. Many companies have introduced various alternatives based on magnetic and fuel saver technology to increase the mileage but none has found to be effective in long run and shows problem in monsoon season. At present, there is no effective alternative present in the market.

Hari Narayan Prajapati, an innovative garage mechanic developed an easily attachable kit for 4 stroke engines to increase the mileage without compromising on power. The kit is fitted in the inlet manifold line between carburettor and inlet valve.

The device introduces a small amount of air ahead of fresh charge thus rectifying the air-fuel mixture. The extra fuel mixture is sucked by the kit and released back to the engine when required and thus involves lesser losses and hence results in increase in mileage. The estimated savings in fuel/petrol consumption is about 10-15 per cent (depending upon air-fuel mixture).
