An engine-generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of self-contained equipment. The engines used are usually piston engines, but gas turbines can also be used, and there are even hybrid diesel-gas units, called dual-fuel units.
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.
A 200 kW Caterpillar diesel generator set in a sound attenuated enclosure used as an emergency backup at a sewage treatment substation in Atlanta, United States. A diesel generator (DG) (also known as a diesel GenSet) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. [1]
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
The International DuraStar line, known as the 4000 series prior to 2008, is a line of medium-duty trucks produced by Navistar International from 2001 until 2018. [1] Introduced as the successor to the International 4000 series of 1989–2001, the 4000 series was renamed the DuraStar in 2008.
The 2008 models of all three CD-2 versions retained the previous generation's engines and transmissions. However, the manual transmission was only available with the four-cylinder and front-wheel drive, and with the XLS trim. For 2009, all three versions received engine and transmission upgrades that increased performance and fuel economy.
A 7 speed dual clutch option is available as standard for the 1.4, a 6 speed manual option is available as standard for the 1.5 and 1.6 litre models alongside an optional CVT for the 1.5 and a 6 speed automatic for the 1.6. Pricing ranges from 109,800 yuan to 146,800 yuan. [56]
The Mirage 4000 was comparable in size to the United States F-15 Eagle, and was designed to be both a long-range interceptor and a fighter-bomber. In the early 1980s, Dassault ended the program shortly after the Royal Saudi Air Force ordered a large number of Panavia Tornado aircraft.
