Front-mounted air-to-air intercooler Top-mounted air-to-liquid intercooler (the silver cuboid-shaped part) on a BMW S55 turbocharged engine. An intercooler is a heat exchanger used to cool a gas after compression. [1] Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas ...
Schematic of a typical turbo petrol engine. The simplest type of turbocharger is the free floating turbocharger. [44] This system would be able to achieve maximum boost at maximum engine revs and full throttle, however additional components are needed to produce an engine that is driveable in a range of load and rpm conditions. [44]
twin-turbo: two electronically controlled turbochargers with variable turbine geometry (VTG) (one turbo per cylinder bank), 2.2 bar (31.9 psi) maximum absolute pressure, combined 4-part inlet manifold and air-to-water intercooler mounted within the vee. With additional side-mounted coolant radiator and additional electric coolant pump
Variable-geometry turbochargers (VGTs), occasionally known as variable-nozzle turbochargers (VNTs), are a type of turbochargers, usually designed to allow the effective aspect ratio (A/R ratio) of the turbocharger to be altered as conditions change. This is done with the use of adjustable vanes located inside the turbine housing between the ...
Diesel engines are typically well suited to turbocharging due to two factors: A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture.
Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. V12 marine diesel engines . Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and warfares.
The turbine itself was designed primarily by Rolls-Royce with significant marine engineering and test facility input from DCN, with Northrop Grumman responsible for the intercooler, the recuperator and system integration. [1] [2] WR-21 development draws heavily on the technology of the successful Rolls-Royce RB211 and Trent families of gas ...
It is related to the Straight-4 OM364 engine which has two cylinders chopped off, while the bore and stroke remain unchanged. [2] It launched in 1983 and had a direct injection system (inline fuel pump) to deliver fuel to every cylinder. It used a twin-scroll turbocharger that was giving ~0.6-0.8atm of boost.
