Transport plays a significant role in the economy of the country. Fuel is the food for transport. Petrol, diesel, autogas, and CNG are significant fuels. It has been observed that the inflation in the price of petrol is the maximum. In 2001 the price of petrol (Mumbai), diesel, autogas, and CNG was Rs.28, Rs.15, Rs.30, and Rs.26 respectively. In 2019 the price of petrol, diesel, autogas, and CNG is Rs.74, Rs.65, Rs.33, and Rs.46 respectively. If the trend continues, petrol is going to be super expensive, and walking will be the best option for humankind.
Amidst all the price hikes, there is an individual who was determined to reduce petrol consumption because decreasing the cost was not in his control. Mr Arvind Khandke, a cloth merchant from Kolhapur, developed a mechanical valve that minimizes petrol consumption by 30%. The perfect example of ‘Jugad’, when you can’t decrease the price reduces consumption.
What’s Mr.Khandke’s method?
Before understanding the method, one must know what carburettor is. It is a part of a vehicle that mixes the appropriate proportion of fuel and air for the engine to ignite. It needs to be set. If it is not fixed correctly, then the engine runs inefficiently or does not start at all.
It was during 1980, Mr Khandke found that the air filter in the vehicle was oily. He thought that the air-fuel mixture was escaping from the carburettor. A valve type device was fit in the carburettor to prevent the wastage. Then in 1983, mild steel was used by him to design the prototype of the valve. But the flap of the valve was heavy. So it did not work efficiently which made him change the material of the flap. He designed a new valve using nylon and polypropylene, which will be appropriate for 1HP to 1.25HP engines.
In 2018, he updated the valve to accommodate a water pressure kit. The reason for adding the water kit was to heat the water and the steam generated from heating can be used as an energy source to enhance the performance of the engine. The average of the engine is increased, and the percentage of petrol supply decreases. There is also a reduction in carbon deposits. This results in slow wear and tear of engine and increases the life span of the engine oil.
The first valve made sure that the air-fuel mixture does not escape from the carburettor and used the air-fuel mixture to the fullest. The version of 2018, in which the water kit was added reduced the petrol consumption by up to 30 per cent.
Initially, Mr Khandke used to change his engine oil for every 2000 km. Now he changes it after 5000 km. He has also patented both his devices.Mr. Khandke developed the valve because of his interest in auto-innovation. He has no plans to commercialize the product — a real example of a man following his passion.
