Four-Stroke Petrol Engine

This animation illustrates the processes inside a four-stroke petrol engine. It serves as a basic introduction to four-stroke petrol engines. Description of the Animation 1. Intake: The valves open. The piston moves downwards. The resulting partial vacuum draws air and fuel into the cylinder, where they mix to form a combustible charge. 2. Compression: The… Read More: Four-Stroke Petrol Engine »

Thermodynamic Processes in a Four-Stroke Petrol Engine

The animation shows the thermodynamic processes taking place inside a four-stroke Otto engine. The four-stroke Otto engine accompanies us every day, often without us noticing: In cars, it drives pistons through exactly four steps – intake, compression, power, exhaust. Lawn mowers, motorcycles, and emergency generators also use this principle. Although modern vehicles are becoming increasingly… Read More: Thermodynamic Processes in a Four-Stroke Petrol Engine »
