Design and Development of a New Pistonusing Nimonic Alloy 80A for Low Cetane Fuels usage in CI Engines

Abstract

In view of the existing fossil fuel deposits may come for another 30 to 40 years and Costs of these Fissile Fuels are day by day increasing. As we know that all over the world the diesel vehicle population is growing at an alarming rate. The emission will irritate skin, eyes, nose and throat and also leads to bronchitis asthma in the long run and has been led to air pollution. It is a serious concern with the pollution point of view. In view of this there is an urgent need for the modifications in the diesel engine technology to suit for emission norms and international standards of emissions norms which do not need major engine modifications. Developing Countries like India depends on its fossil fuel requirements on foreign countries for which spars a huge foreign currency in purchase of crude oil. Thus the inflation rate increases, rupee valve decreases and hence the country’s economy and development decrease. The increasing pressure on crude oil reserves and environmental degradation as an outcome.Hencein view of the above drawbacks there is an urgent need to find an alternative fuels in the existing engines.Fuelslike (Low Cetane Fuels) like Vegetable oils may promise and present a sustainable solution as it can be produced from a wide range of plants and seeds. The present investigation evaluates the Design and Development of a New Piston using Nimonic Alloy 80A for Low Cetane Fuels usage in CI Engines. Design is done using Catia –V 5 software and Production is being done in CNC machining using programming.
