Reduction in fuel consumption in IC engines

Towards it’s mission to promote innovation through research by making it more open and participative, Knimbus has instituted the “Knimbus Young Innovator” Award.

Over 900 teams from 600+ colleges across India participated in the competition with their innovative ideas and project submissions.  Finally, we shortlisted 20 entries and amongst our top 20 entries, here is one such entry:

 

This innovate idea will help to save fuel and some money  and will drastically improve the efficiency of your engine. 

 

Abstract:

 

In this paper we propose a modification to the engine design which can use two different fuels simultaneously to extract work from the engine and reduce the consumption of conventional fuel. In this concept we are using hydrogen as the first fuel along with conventional fuels. In this concept, cylinder of the engine has two thermodynamic systems which works on Otto Cycle or Diesel Cycle and are separated by the moving boundary which is the piston. The four strokes of the Otto Cycle or Diesel Cycle works alternatively in the two systems. The two chambers of the cylinder have their own intake, exhaust and fuel injection systems. Conventional fuel is used in the chamber above the piston and hydrogen below it and the strokes of this engine are altered in such a way that the power stroke produced by conventional fuel aids in compressing the air in the other chamber during the compression stroke. The hydrogen is injected by high pressure direct injection and is ignited by compression ignition. The power output of a direct injected hydrogen engine is 20% more than that of a gasoline engine and 42% more than a hydrogen engine using a carburetor. Because of hydrogen’s wide range of flammability, hydrogen engines can run on air-fuel ratios from 34:1 (stoichiometric) to 180:1 and can ignite at very low temperatures. The strokes in the lower chamber can be initiated by just supplying heat energy to the cylinder block. Hydrogen can be produced on- board by accelerated electrolysis process of water and is stored. This engine can also run using one fuel in case of absence of the other since both the systems work independently. Our concept of using hydrogen could be promising as it reduces the fuel consumption by large extent and coul answer to the depleting recourses.

Things You Should Know about Research in India

When was the last time you heard India invented something remarkable?  Recently, Prof Rao was addressing press conference a day after the Bharat Ratna award was announced, stressed on the need for providing more resources for research.

“The future of India stands with science let me tell you only countries which have really made progress in the world are those which are scientifically advanced and those which are not scientifically advanced are not known,” Rao said.

Rao went on to say that starting next year, China will top the world with 16.5 per cent of world research publications, overtaking even the US. The quantity of publication of research papers from India have remained at 2-3 per cent.

At a time when India is being looked at as the next big knowledge superpower, this could come as a shocker. Just 3.5% of global research output in 2010 was from India. While India’s research on physics was 4.6% in 2010, China’s stood at 19%.

Few days ago our Prime Minister said “As far as higher education in science and technology in our country is concerned, there are massive challenges that lie ahead,”

Now just in higher education, there are many more challenges faced in research.  The research methodology is not systematic. Many researchers undertake research work without having actual knowledge of the research methods. Getting the Research sponsored  is again a challenge. There is not efficient interaction between researchers and the business establishments, government institutions, etc. This leads to a great deal of data going

Abstract:


Myocardial Infarction, commonly known as cardiac arrest, is the most common disorder in the present scenario. This is due to the stress developed in the heart. This stress may be due to fat or cholesterol accumulation and also due to hypertension. Here we can use a micro SONAR to detect this fatal disorder before. This micro SONAR is placed over a NANO ROBOT which travels to the coronary artery and gets fixed to the walls of the artery. This NANOBOT movement is controlled wirelessly by infrared radiation or radio (including Bluetooth). Hence high speed wireless movement is achieved. This micro SONAR sends some ultrasonic sound waves (above 18,000 Hz), bistatic micro SONAR, within the blood vessel (inferior and superior venacava, aorta and mainly coronary artery). If these sound waves are blocked by the plaque, then a portion of sound waves won’t be reaching the receiver since they are reflected back and hence the transducer which is fixed to the SONAR sends the Radio Frequency waves to the patient’s mobile phone through the server. Here there is another micro monostatic SONAR which senses the diameter of the blood vessel (useful during hypertension and stress) and it transmits the data to the mobile phone.
