摘要：In Today’s world development of automobile technology is boom to the world, in that increasing theengine performance lead a major role in it. Therefore in order to improve the efficiency of an engine different types ofmaterial and techniques are used to improve the performance. In this paper a new design of an IC engine is presentedwhich has better characteristic features than its predecessors and can add up to technological advancements in the field.Technically, the concept is to add one more stroke in a classical four stroke cycle in order to extract more work. .Thefour stroke engine exhaust gases at high temperatures having energy which could be used further to extract more work.With this concept of extracting more work, a new design is made with the ultimate target of increased efficiency anddecreased structural weight. It is found that, addition of one more stroke in a four-stroke IC engine results in increase ofexpansion ratio and thermal efficiency. It is made possible with the help of an extended expansion stroke which iscarried out in a low pressure cylinder which has larger volume compared to the two high pressure cylinders. Theextended stroke helps in producing more power output and torque, consuming less amount of fuel-mixture and hencemaking it more efficient. The 5 stroke engine which has an additional exhaust gas energy recovery is very interestingfrom a research point of view.
