• All internal combustion engines are characterized by a four part cycle of operation. The four parts are: 1. Intake, 2. Compression, 3. Combustion, and 4. Exhaust. A fuel/air mixture must be drawn into the engine, compressed, burned, and exhausted. A two-stroke engi ne uses only two strokes to accomplish all four parts. Each of the four parts can be easily understood by fol/owing the path of the fuel/air mixture through the engine (Figure 2-1). 1. Intake: On the upstroke of the piston a charge of fuel mixed with air is drawn into the engine through an open port in the cylinder. 2. Compression: Near the bottom of the downstroke, the intake port is closed, and the piston starts back up. This upstroke compresses the fuel/air mixture to a fraction of its former volume. 3. Combustion: When the mixture has been compressed, it is ignited and forces the piston down. This is called the power stroke. 4. Exhaust: After the power stroke, the burned gases exit through the now open exhaust port, and the cycle is ready to start again. The piston is carried through each step from one power stroke to the next by the rotating inertia of the crankshaft. The intake of a two-stroke engine is perhaps the most complex part of the cycle. After the fuel and air have been mixed in the carburetor, it is drawn into the crankcase. As the piston rises, a hole in the cylinder wall (the intake port) is uncovered by the lower edge of the piston. The rising piston effectively increases the volume of the crankcase, drawi ng in the mixture. On its return trip, the piston blocks the intake port and lightly compresses the mixture in the crankcase. At about 55°-60° BBDC (before bottom dead center), the upper edge of the piston uncovers ports in the cylinder wall that are connected to the crankcase. The mixture in the crankcase, under pressure, rushes through these transfer ports into the cylinder.
