Internal guide:Ms. BHAVANI,Asst. professor, MECH. DeptOverviewThere have been a number of axial engines designed over the years with some similarities between them, but these examples from Duke Engines of New Zealand show a very impressive and well developed prototype. Arthur, one of our readers, spotted the engine on display at the recentEAA airventure in Oshkosh, Wisconsin and thought you might be interested. The engine has 5 cylinders, 3 injectors and zero valves.ENGINEAn engine is a machine designed to convert energy into useful mechanical motion

To increase the power the number of cylinders are been increased either by linear or v- shaped increasing the weight and complexity

The duke engine reform the linear motion to circular creating a true axial engine

Axial engineAxial engines (sometimes known as barrel or Z-crank engines) are a type of reciprocating engine with pistons arranged around an output shaft with their axis parallel to the shaft.

Duke engineDuke Engines are in an advanced stage of developing a unique high-speed, valve-less 5 cylinder, 3 injector axial internal combustion engine

Reciprocator in tern rotates the crank shaft in opposite directionWith only 5 cylinders requiring only 3 spark plugs and 3 fuel injectors.The engine has as many power stroke a the engine of 6 cylinders But at least 30% less weightAnd also outstanding reduction in the number of partsADVANTAGESResistant to pre-ignitionHigher compression ratiosLow VibrationHigh power in small sizeLess partsRuns on multiple fuelsAPPLICATIONSMARINEAERO SPACEconclusionThe Duke Engine is far less complex than traditional IC engines. The Duke Engines much lower part and component count (only 3 sets of spark plugs, injectors and ports for 5 cylinders with no valve train), coupled with ease of repair and maintenance and potentially lower production costs, offer potential for savings in manufacturing and operation.Thank you.
