Design of Six-Stroke Internal Combustion Spark Ignition Engine

Abstract

The rate at which energy is lost by human activities is enormous. There is need to work on how to generate more energy and minimize the usage of the generated energy. In an internal combustion engine, there is a need to focus on gaining energy usage by using generated heat during the combustion process. To reduce the energy usage, emission rate and improve the efficiency of four-stroke internal combustion spark ignition engine, the four-stroke internal combustion spark ignition engine is modified into a six-stroke internal combustion spark ignition engine. The heat generated from a four-stroke cycle is used in a six-stroke cycle for additional power stroke and exhaust stroke of the piston in the same cylinder. There is an injection of water which forms steam with the help of generated heat from a four-stroke cycle which forces down the piston for additional power stroke and the piston comes up to expel the exhaust gases out of the cylinder. With the injection of water into the cylinder, there is no need for a cooling system as in a four-stroke Otto cycle which makes the engine become lighter and 25% fuel and power efficiency over the normal Otto cycle.
