Abstract:

The greatest discovery of mankind is fire. It is from fire we obtain heat energy which forms the base for all kinds of energy. The modern world thrives on heat energy used in different forms. Transportation was made easy and comfortable due to the invention of automobiles which is ultimately powered by heat energy. Every day new advancement is made in the field of automobiles. Automobile industry is ever-growing industry and all the new developments are made to increase human comfort and to make traveling a pleasure. But the conversion rate of energy from one form to another is very minimal. Almost 95% of the automobiles run on IC engines which are powered by fossil fuels. As we all know that fossil fuels are getting exhausted. So we must use the gift of nature (fossil fuels) very efficiently. The ultimate aim of thermal engineering is to convert the heat energy to mechanical energy completely, but the maximum energy conversion ratio is limited in practical implementations. The main application of thermodynamics is in the field of automobiles. The efficiency of an automobile is around 30%. Since its inception, the internal combustion (IC) engine has undergone continuous improvements with respect to efficiency and performance. Future regulatory and environmental requirements are not only driving still further improvements, but also extending the propulsion system efficiency through hybridization and potentially obsolescing the IC engine with hydrogen fuel cells and some new innovative thinking.

This paper describes the potential IC engine improvements to meet tomorrow's challenges and the associated business and technical challenges in obtaining these challenges. Hence we go in for a new alternative to four stroke engine THE SIX STROKE ENGINES. The critical role of the IC engine in this portfolio is examined.
