Duke Engine: An Overview of Present State of Art and Future Potential

Sidharath Joshi

Abstract: During the past three centuries, there has always been an emphasis on development of a kind of engine that has superior efficiency, less polluting and good power generation. Among them, a recent innovation is duke engine. It is an advanced stage of simple 4 stroke IC Engine which is capable of producing high speed with low vibrations, has an axially arranged arrangement with five cylinder and three injector systems. This engine has a negligible first order vibration and is also expected to have low vibrations in higher order running. Being compact in size, there is more reduction in weight and on the other hand, it is capable of generating heavy torque. This 3rd generation engine has the ability to run on different combustible fuels and petroleum products at different octane level. Thus it has potential in replacement for petroleum based fuels such as biofuels, compressed natural gas, liquefied petroleum gas, suitable mixtures with Methanol/ Ethanol, Hydrogen etc. Due to utilisation of less components, there is reduction in manufacturing and production cost that could lead to great economic value. This engine delivers a superior torque at high power density and a counter rotating cylinder leading to cancellation of gyroscopic forces. In this review, an effort has been done to highlight various aspects of Duke Engine.
