About Radial Engines
The roar of the propellers echo as the airplane soars overhead. These propeller planes use a radial engine to power them through the air. Unlike engines for a car or motorcycle, radial engines have their pistons arranged in a circular pattern. They have anywhere from three to nine cylinders and the pistons are arranged around the crankshaft. Just like four-stroke engines, they have require pistons, valves, and spark plugs in order to operate. Large and powerful radial enginers were used mostly during World War II, but today they are commonly used in models or kept as part of a collection. These engines are an important part of history, and make an excellent addition to any collection. Complete engines, replicas, and parts for engines are readily available on eBay, so you can find just what you need for your radial engine. Enjoy a unique part of history and learn more about engines in the process by adding a radial engine to your collection.
