DESIGN AND ANALYSIS OF A TWO STROKE I.C.ENGINE Prepared by: Suraj Jose Amit Modi Vishal Panchal Vishal Modha Guided by: Mr. H. K. Solanki DEPARTMENT OF MECHANICAL ENGINEERING MAHATMA GANDHI INSTITUTE OF TECHNICAL EDUCATION AND RESEARCH CENTRE, NAVSARI, GUJARAT.
Worried of running out of petrol every time you get on the roads??? Just Relax!!! Because we are introducing a concept which will increase the thermal efficiency of the engine upto some extent. By introducing our concept, we are able to increase the temperature of the inlet air by using the concept of a non contact type heat exchanger by utilizing the temperature of exhaust gases. INTRODUCTION
Minimize the requirements for addition of new complicated parts particularly moving parts. Minimal interference in the moving parts, mechanisms and control systems. Maximize the positive effect from operation of strokes of the existing engines. THE MAIN AIMS OF THE PROJECT
Easy to introduce into the vehicle with minimum cost. Achieve optimum possible work out from the vehicle. It should be eco-friendly (i.e. minimum pollution).

Speed, km/hr Efficiency (η), % Heat Supplied, KJ/Kg 2069.153.4326 2569.153.5988 3569.144.2106 Result without increasing the inlet air temperature
ADVANTAGES Ignition lag time decreases. Uniform air-fuel mixtures obtained. Modification is not complicated. One time investment. Easily replaceable if damaged. Cost efficient.
DISADVANTAGES This concept cannot be applied to Compression Ignition Engines (diesel engines). The design and structure of the silencer body becomes a bit complicated. Instant result may not be obtained. A decrease in the efficiency may be observed if size of the copper tube is not selected properly.
CONCLUSIONS After performing the tests on the vehicle, and from the observations made, we can conclude that the efficiency does not increase as per the theoretical concept due to the following reasons: Variation in the actual air filter tube size and used copper tube. Due to improper wounding of copper tube. Due to the rise in air temperature, the volume of fuel is increased, as a result a rich mixture is obtained.
FUTURE SCOPE We are confident that the efficiency would increase if further changes can be carried out in the project. The major research options which are applicable to this project are as follows: Use copper tube of different size diameter. Check the Emission and the noise level.
Use of the temperature control device to vary the temperature as desired. To try different materials to achieve higher heat transfer. To check the compatibility with other vehicles.
