{"Image DocumentName": "According to Strokes/Cycle.", "Image ImageDescription": "In an engine, the following events form a cycle: Filling the engine cylinder with fresh air. Compressing the air so much that injected fuel ignited readily by coming in contact with hot air and burns efficiently. Combustion of fuel. Expansion of hot gases. Emptying the products of combustion from the cylinder. Depending on how many strokes of piston are required in completing this cycle, the engines can be divided into two classes: 1. Four Stroke Engine. An engine, which needs 4 strokes of the piston (2 in and 2 out) to complete one cycle, is called Four-stroke engine. 2. Two Stroke Engine. An engine that needs only 2 strokes of the piston (1 in and 1 out) to complete one cycle is called Two-stroke engine.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
