 | Radial Engine Info? I have questions about the inner workings of a radial engine. Can anyone direct me to a website that has some detailed pics or diagrams? Maybe even a Message board? I understand the basic concept of the Radial, my questions are rather detail oriented. I understand that all of the cylinders in a given row share the same crankshaft journal, they do this by using a "Star" assembly that centers on the crank journal, while the "Points" of the star hold the ends of the connecting rods. I've seen this in a motorized cutaway at the Smithsonian. What I want to know, is what keeps the star in "phase" with the Cylinders? Why does it not just rotate off center and lock up the engine? Also, I need details on the oil control system. |

| Here is a site about radials.... The thing that keeps the everything together internally is called a "Master Rod" and how it is connected to the crank case... http://www.aviation-history.com/engines/radial.htm http://travel.howstuffworks.com/radial-engine2.htm http://auto.howstuffworks.com/question331.htm Oil is usually fed under pressure from a seperate sump, this is called a dry sump system..
