The John Deere PowerShift transmission was an eight-speed semi-automatic transmission without a torque converter, used in John Deere tractors, including the iconic John Deere Model 4020. [1] The Powershift is not to be confused with similar John Deere transmissions (including the Quad-Range and the PowrQuad [ 2 ] ), or with the Ford Ultra ...
Quadrajet carburetors have mechanical secondary throttle plates operated by a progressive linkage; the primaries open before the secondaries, and use on-demand air valve plates above the secondary throttle plates. The air valves are connected by a cam and linkage to the secondary fuel metering rods.
CF34 engine mounted on an Embraer 190 Recent versions of the CF34 feature chevrons on the core nozzle outlet.. The General Electric CF34 is a civilian high-bypass turbofan developed by GE Aviation from its TF34 military engine.
CFM is the world's largest commercial aircraft engine manufacturer, with a 39% market share as of 2020. [1] It has delivered more than 37,500 of its engines to more than 570 operators. The name CFM is derived from the two parent companies' commercial engine designations: GE's CF series and Snecma's M series.
Time between overhauls (abbreviated as TBO or TBOH) is the manufacturer's recommended number of running hours or calendar time before an aircraft engine or other component requires overhaul.
The CFM International LEAP ("Leading Edge Aviation Propulsion") is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between American GE Aerospace and French Safran Aircraft Engines. It is the successor of the CFM56 and competes with the Pratt & Whitney PW1000G to power narrow-body aircraft.
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
CFM International announced the RISE program in June 2021 as an intended successor of the CFM LEAP turbofan engine, with plans to enter service in the mid-2030s. At the 2022 Farnborough Airshow in July of that year, CFM International and Airbus announced plans to start flight tests for the RISE engine on an Airbus A380-based testbed in 2026. [7 ...
