What is the principle of the Atkinson cycle engine?

[AdrianaDella]

The working principle of the Atkinson cycle engine is to extend the power stroke and shorten the compression stroke, making the expansion ratio greater than the compression ratio, thereby more effectively utilizing the residual high pressure of the exhaust gas after combustion. The fuel and air mixture burns, generating heat energy, and the gas expands when heated, converting into mechanical energy through mechanical devices to perform external work. Below is more information about the Atkinson cycle engine: 1. Introduction: The Atkinson cycle engine improves efficiency but reduces power density, with the drawback of lower efficiency and poorer torque at low speeds. 2. Application: The Atkinson cycle engine is currently used in some hybrid vehicles. Hybrid vehicles are those powered by two or more energy sources, and the drive system can have one or more sets. Common energy sources include fuel, batteries, fuel cells, solar cells, compressed gas, etc., while common drive systems include technologies such as internal combustion engines, electric motors, and turbines.
