neljataktilised

Neljataktilised refers to four-stroke engines, a type of internal combustion engine. These engines operate in a cycle of four distinct piston strokes: intake, compression, power, and exhaust. During the intake stroke, the piston moves down, drawing a fuel-air mixture into the cylinder. The compression stroke follows, with the piston moving up to compress this mixture. At the top of the compression stroke, the spark plug ignites the compressed fuel-air mixture, initiating the power stroke. This combustion forces the piston down, generating the engine's power. Finally, in the exhaust stroke, the piston moves up again, pushing the burnt gases out of the cylinder. This cycle repeats continuously to produce mechanical energy. Four-stroke engines are widely used in automobiles, motorcycles, and many other applications due to their relatively good fuel efficiency and lower emissions compared to two-stroke engines. The design allows for separate lubrication systems, contributing to their durability and performance.
