avgasator

An avgasator is a device used in aviation to mix aviation gasoline (avgas) with oil. This mixture is necessary for certain types of aircraft engines, particularly older two-stroke engines and some vintage aircraft. The avgasator ensures that the correct ratio of fuel to oil is maintained, which is crucial for proper lubrication and engine performance.

There are various types of avgasators. Some are simple manual mixing devices where the pilot or mechanic measures and combines the fuel and oil themselves before adding it to the aircraft's fuel tank. Others are more sophisticated, often referred to as oil injection systems, which automatically meter the oil into the fuel flow as the engine operates. These automatic systems are designed to provide a consistent and precise mixture, adapting to varying engine loads and speeds.

The purpose of mixing oil with avgas in these specific engines is to provide lubrication for internal engine components, such as pistons, cylinders, and crankshafts, as the oil is burned along with the fuel. Modern aircraft engines typically use separate oil systems for lubrication, but avgasators remain relevant for maintaining older aircraft and specific engine designs. Proper operation and maintenance of an avgasator are essential to prevent engine damage and ensure flight safety.
