Woodward, Inc. is an American designer, manufacturer, and service provider of control systems and control system components (e.g. fuel pumps, engine controls, actuators, air valves, fuel nozzles, and electronics) for aircraft engines, industrial engines and turbines, power generation and mobile industrial equipment. The company also provides ...
If the electrical part of the control should fail, an EEC will revert to a standard hydromechanical fuel control. Full-authority digital engine control (FADEC): A digital computer which controls a servo-operated fuel valve. In this case the power lever is only electrically connected to the fuel control.
In 2009, the L'Orange Fuel Injection Trading (Suzhou) Co., Ltd. subsidiary was founded in China. In 2014, L'Orange founded its third production location in Ningbo (China), which was also the first plant to be established outside Germany. In April 2018 Rolls-Royce Power Systems sold the company to its competitor Woodward in the USA. [2] [3]
The fuel level indication system in the simplest form is a transparent window on the tank side and in its usual application a float-driven potentiometer installed in the tank. After the TWA Flight 800 disaster, a revision was made to aircraft fuel systems to address the potential explosion hazard of electrical components located in the fuel tank.
Fuel primer pump - A manual pump to add a small amount of fuel at the cylinder intakes to assist in starting a cold engine. Fuel-injected engines do not have this control. For fuel-injected engines, a fuel boost pump is used to prime the engine prior to start. Fuel quantity gauge - Indicates the amount of fuel remaining in the identified tank ...
A Digifant II DF-1 Engine Control Unit used in '91 Volkswagen Golf Cabriolet with 2E engine. Digifant is an Engine Management System operated by an Engine Control Unit that actuates outputs, such as fuel injection and ignition systems, using information derived from sensor inputs, such as engine speed, exhaust oxygen and intake air flow.

The float is lifted upward by inertia, closing the fuel inlet valve as if the fuel bowl was full of fuel. Cutting off the fuel supply causes the fuel-air ratio to become greater than sixteen to one, which is then too lean for combustion to take place, stopping the engine. [10] [11] The inverse is also true when the aircraft is in inverted ...
An onboard refueling vapor recovery system (ORVR) is a vehicle fuel-vapor emission control system. It captures potentially harmful volatile organic compounds (VOCs) during refueling. [ 1 ] Without such a system, fuel vapors trapped inside gas tanks would be released into the atmosphere, each time the vehicle was refueled.
