Abstract
This paper reviews the progress made since the last SAE Congress in the development and testing of the Collins Scotch Yoke crankshaft technology and the demonstrator engine in which it is being proven.
New packaging refinements are illustrated, and more detailed internal friction loss data are shown. New fuel consumption data are shown to confirm the low internal friction losses of the demonstrator engine.
A study of the potential of supercharging illustrates the power increase that can be achieved with virtually no increase in engine packaging volume.
A discussion is also provided of the unique, exact engine balancing that is possible with the scotch yoke technology, due to the pure sinusoidal motion of the pistons and con rods.
Finally, a brief discussion is provided of the small crevice volumes that may be achieved with the Collins Scotch yoke technology.
