PROGRESS PICTURES OF THE 14 CYLINDER SLEEVE VALVE ENGINE.

 

The model is 1-3/8 bore by 1-5/8 stroke - 38 cu.in. displacement ( 550 cc ) 

 

I thought you might enjoy seeing the progress on the parts.

Picture 1 :

NEW - The cylinders & cylinder heads mounted on the crankcase,

With those 29 gears. Notice the crankcase profiling.

    The crankshaft is installed and driving the oil pumps. 

 

The finished engine is getting closer !

 

This is why they call a sleeve valve engine - A Swiss watch running at 2500 HP !

Some history of the sleeve valve project 

 

                      In the 1960's I was fortunate to hear a Willys-Knight sleeve valve automobile

               engine run.  I was fascinated by an engine with no poppet valves. Instead there

               were two concentric hollow sleeves moving vertically up and down with a piston

               inside. The nickname for the car was the " Silent Knight ", because of its very 

               quiet operation.  

 

                            I was delighted to learn, years later, that before and during WW II the Bristol

               Engine Company in England built a series of remarkable sleeve valve radial 

               aircraft engines. 

 

                            The principal was different from the automobile engine I had seen years 

               before.  In these engines, there was a single sleeve operating inside each cylinder.

               Each sleeve makes an elliptical path, operated by its own small crank, running at

               half speed of the crankshaft. 

 

                            The pinnacle of this work was the 14 cylinder " Hercules " and the

               18 cylinder " Centaurus ". 

 

                             I have been working on this engine for quite some time.

                I hope this gives you some insight into the project.
