Förbränningsmotor

Förbränningsmotor is the Swedish term for an internal combustion engine. This type of engine converts chemical energy stored in fuel into mechanical energy through a process of combustion. The combustion occurs within a confined space, typically a cylinder, where a mixture of fuel and air is ignited. The rapid expansion of gases generated by the combustion exerts pressure on a piston, causing it to move. This linear motion is then converted into rotational motion by a crankshaft, which can be used to power various machines, most commonly vehicles.

There are several types of internal combustion engines, with the most prevalent being the spark-ignition engine (gasoline engine) and the compression-ignition engine (diesel engine). Spark-ignition engines use a spark plug to ignite the fuel-air mixture, while compression-ignition engines rely on the heat generated by compressing the air to ignite the fuel. The four-stroke cycle, consisting of intake, compression, power, and exhaust strokes, is the most common operating principle for both types. The efficiency and emissions of internal combustion engines have been a significant area of development and regulation.
