May i request for a sample impression message after seminar. I believe this would help me prepare myself for new trainings that i am going to attend and i am quite sure this would help me in my new position as a head. Thank you

yes it will surely help me to prepare for paper presentanton.

duke engine ppt

Technology Overview

Duke Engines are in an advanced stage of developing a unique high-speed, valve-less 5 cylinder, 3 injector axial internal combustion engine with zero first-order vibration, significantly reduced size and weight, very high power density and the ability to run on multiple fuels and bio-fuels. The Duke engine is suited for many uses including marine, military, automobile, light aircraft and range extender applications.

There 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 recent EAA Airventure in Oshkosh, Wisconsin and thought you might be interested. The engine has 5 cylinders, 3 injectors and zero valves.

The pistons are all attached by their connecting rods to a reciprocator which rotates as a result of the movement of the pistons and is itself attached to the crankshaft which rotates in the opposite direction. As the pistons move through their strokes, they also move past the ports, injectors and spark plugs, eliminating the need for valves. It's a very ingenious arrangement.

The axial engine has a number of interesting features:

The counter rotating components generate very low vibration
Only 3 injectors and plugs for 5 cylinders plus no valve train reduces the parts count
It is designed to run on a wide variety of fuels
Lighter and more compact than similar displacement conventional engines
