Liquid air cycle engine - A liquid air cycle engine (LACE) is a spacecraft propulsion engine that attempts to gain efficiency by gathering part of its oxidizer from the atmosphere. In a LOX/LH2 bipropellant rocket the liquid oxygen needed for combustion is the majority of the weight of the ...
Air cycle machine - An Air Cycle Machine (ACM) is the refrigeration unit of the environmental control system used in pressurized turbine-powered aircraft. Normally an aircraft has two to three of these machines arranged in a system called a "pack".
Four-stroke cycle - The four-stroke cycle of an internal combustion engine is the cycle most commonly used for automotive and industrial purposes today (cars and trucks, generators, etc). The Thermodynamics cycles used in internal combustion reciprocating engines are the Otto Cycle (the ideal cycle for spark-ignition engines) and the Diesel Cycle (the ideal cycle ...
Four-stroke cycle engine valves - Four-stroke engines, of either spark ignition or compression ignition varieties, use poppet valves to allow air (or an air/fuel mixture) into the cylinder and exhaust gases out. Very early engines used alternative valve types such as slide valves, but these proved less satisfactory, especially for high-speed engines.
