The Quad 4 is the first wholly domestic regular production DOHC four-cylinder engine designed and built by GM, the only similar prior example being the Chevrolet Cosworth Vega, whose DOHC head was designed by Cosworth in England. In addition to the 2.3-liter DOHC Quad 4s, there was also a short-lived 2.3-liter SOHC variant called the "Quad OHC ...
It used stretched C3 Chevrolet Corvette underpinnings, coupled to fibreglass bodywork. [3] As for the Corvette, power steering and brakes, powered tinted windows, and tilt steering were fitted. The fuel-injected 5.7-litre V8 engine in the 1982 Berlinas offers 200 hp (149 kW) at 4,200 rpm, for a top speed of around 180 km/h (110 mph). [ 2 ]
Dassault Falcon 200. Dassault HU-25 Guardian. Number built. 200+. The Garrett ATF3 (US military designation F104) is a 3-spool turbofan engine developed at the California division of Garrett AiResearch. Due to mergers it is currently supported by Honeywell Aerospace. The engine's design is unusual; the core flow path is reversed twice.
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
Walker circulation. A schematic diagram of the quasi-equilibrium and La Niña phase of the southern oscillation. The Walker circulation is seen at the surface as easterly trade winds which move water and air warmed by the sun towards the west. The western side of the equatorial Pacific is characterized by warm, wet low pressure weather as the ...
The turbochargers are located on the outside of the engine and use a boost pressure of 11.6 psi (0.8 bar). [1] In its base configuration the engine has a compression ratio of 10:1 and a specific fuel consumption of 245 g·kW −1 ·h −1. [2] Like its predecessor, the N74 has direct injection, DOHC and variable valve timing (called double ...
Engine Alliance GP7000. The Pratt & Whitney PW4000 is a family of dual-spool, axial-flow, high-bypass turbofan aircraft engines produced by Pratt & Whitney as the successor to the JT9D. It was first run in April 1984, was FAA certified in July 1986, and was introduced in June 1987. With thrust ranging from 50,000 to 99,040 lbf (222 to 441 kN ...
The YJ93 started life as the General Electric J79-X275, an enlarged version of the General Electric J79 turbojet with "275" meaning Mach 2.75, the engine's target operating speed. [2] This design evolved into the X279 when Mach 3 cruise became a requirement, and ultimately became the YJ93. [3] The engine used a special high-temperature JP-6 fuel.
