pistongsmotorer

Pistongsmotorer, also known as reciprocating engines, are a type of internal combustion engine where the expansion of high-temperature gas in a cylinder pushes a piston. This piston is connected to a crankshaft via a connecting rod, which converts the linear motion of the piston into the rotary motion of the crankshaft. This rotary motion is then used to power a vehicle, generator, or other machinery.

The basic principle involves a four-stroke cycle: intake, compression, power, and exhaust. During the intake stroke, a mixture of fuel and air is drawn into the cylinder. In the compression stroke, the piston moves up, compressing this mixture. The power stroke occurs when the compressed mixture is ignited, creating an explosion that forces the piston down. Finally, the exhaust stroke expels the burnt gases from the cylinder. Two-stroke engines achieve the same result with fewer movements, combining some strokes.

Pistongsmotorer are widely used in automobiles, motorcycles, airplanes, and many other applications due to their relatively high power-to-weight ratio and versatility. They can be powered by various fuels, including gasoline, diesel, and natural gas. Despite the emergence of alternative technologies like electric motors, pistongsmotorer remain a dominant force in many sectors of the global economy. Their design has evolved significantly over time, leading to improvements in efficiency, emissions reduction, and performance.
