However, uncooled EGR designs do exist; these are often referred to as hot-gas recirculation (HGR). Cooled EGR components are exposed to repeated, rapid changes in temperatures, which can cause coolant leak and catastrophic engine failure. [9] [10] Unlike spark-ignition engines, diesel engines are not limited by the need for a contiguous ...
[77] [full citation needed] In turbocharged engines, EGR needs a controlled pressure differential across the exhaust manifold and intake manifold, which can be met by such engineering as use of a variable geometry turbocharger, [citation needed] which has inlet guide vanes on the turbine to build exhaust backpressure in the exhaust manifold ...
The Prince family shares its basic block dimensions with the previous PSA TU engine family. Engineering design was directed by BMW using their Valvetronic variable valve lift system on the intake side, flow-controlled oil pump, timing chain, single belt drive of all ancillary units, composite camshafts and cylinder head produced by lost-foam casting.
The BMW iX is the first vehicle to feature the iDrive 8 that combines a 12.3-inch digital instrument cluster with a 14.9-inch infotainment touchscreen to form a single curved unit. The system comes with an upgraded version of BMW's personal voice assistant and retains the iDrive controller.
BMW 2800CS. The first of the E9 coupés, the 2800 CS, replaced the 2000 C and 2000 CS in 1968. The lead designer was Wilhelm Hofmeister. [2] [3] The wheelbase and length were increased to allow the engine bay to be long enough to accommodate the new straight-six engine code-named M30, and the front of the car was restyled to resemble the E3 sedan.

This approach relies on observation and experimental data. It is specifically tailored to the geometrical shape of the vortex tube and the details of its flow and is designed to match the particular observables of the complex vortex tube flow, namely turbulence, acoustic phenomena, pressure fields, air velocities and many others.
Channel 9 (Russian: 9 канал, IPA: [ˈdʲevʲɪtʲ kɐˈnaɫ]) is a television station in Israel, formerly known as Israel Plus (Russian: Израиль Плюс). It primarily broadcasts in the Russian language usually with Hebrew subtitles.
Launched in 2004 when Microsoft's corporate reputation was at a low, [2] Channel 9 was the company's first blog. It was named after the United Airlines audio channel that lets airplane passengers listen to the cockpit's conversations unhindered; the site published conversations among Microsoft developers, rather than its chairman Bill Gates ...
