T603 engine designed by Julius Mackerle. http://www.eurospares.com/graphics/engine/...searcheable.pdf (thanks jd74914 ) By raising the camshaft far above the crank in the valley,the rocker geometry for the exhaust valve is improved,perhaps making possible the use of common rockers throughout. Note the hemi-like chamber and wide angle canted valves.Like the VW/Porsche and Corvair,the bore diameter is restricted by the cylinder head studs. A considerable amount of weight savings would be realized by adopting LN cylinders. I believe the crank is a conventional cross plane and at a small 72mm stroke,there may be plenty of room for a much larger stroker. http://www.velocetoday.com/a-technical-history-of-tatra/ The discrete lifter-blocks allow replacement roller-lifter and barrels to be installed for low friction,high rpm operation. |
