Ottosyklillä

Ottosyklillä is a term used to describe a specific type of internal combustion engine operating cycle. It refers to the Otto cycle, a thermodynamic model that describes the functioning of a typical spark-ignition piston engine. The cycle consists of four distinct phases: intake, compression, power (or combustion), and exhaust. During the intake stroke, a mixture of fuel and air is drawn into the cylinder. This mixture is then compressed by the piston in the compression stroke. At the top of the compression stroke, a spark ignites the fuel-air mixture, causing a rapid expansion of gases in the power stroke, which pushes the piston down. Finally, the exhaust stroke expels the burnt gases from the cylinder. The Otto cycle is a theoretical model and real-world engines deviate from it due to factors like friction and heat loss. However, it provides a fundamental understanding of how spark-ignition engines convert chemical energy into mechanical work. The efficiency of an Otto cycle engine is influenced by its compression ratio. Higher compression ratios generally lead to greater thermal efficiency. The term "Ottosyklillä" is the Finnish equivalent of "by the Otto cycle" or "using the Otto cycle."
