DESIGN AND EXPERIMENTAL CONSTRUCTION OF A SIX-STROKE ENGINE WITH WATER INJECTION

Internal Combustion Engines can be found under the hoods of 98% of the estimated 1.2 billion cars in the world. The quest for engines with better power and greater fuel efficiency has been persistent for a great number of years. New ideas and technologies have been incorporated into the current system in order to reduce the consumption of fuel. A six-stroke I. C. engine will radically improve on the concept of a four-stroke I. C. Engine. It will increase the fuel efficiency and improve the heat dissipation of the engine, thereby eliminating the need for a radiator. The six-stroke engine concept will add two strokes of water to the original four-stroke cycle. The fifth stroke in the cycle will act as an auxiliary power stroke. This type of engine will have positive implications on the environment as it will reduce emissions. The paper gives a detailed description of the design changes that need to be incorporated for the engine to run on a six-stroke cycle. It also gives an insight into the various thermodynamic process changes that occur on converting a four-stroke engine into a six-stroke engine along with the various parameters that have to be taken into consideration. The Crower Six Stroke engine is the basis for this design idea.
