Using a turbocharger spool valve to increase exhaust gas flow speed to the (twin-scroll) turbine; Using a butterfly valve to force exhaust gas through a smaller passage in the turbo inlet; Electric turbochargers [52] and hybrid turbochargers. A similar phenomenon that is often mistaken for turbo lag is the boost threshold. This is where the ...
A mechanically driven supercharger offers exceptional response and low-rpm performance, as it does not rely on pressurization of the exhaust manifold (assuming that it is a positive-displacement design, such as a Roots-type or twin-screw, as opposed to a centrifugal supercharger, which does not provide substantial boost in the lower rpm range), but is less efficient than a turbocharger due to ...
In an internal combustion engine, twin-turbo is a layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine 's produced exhaust through ...
The newest version of the most powerful Panamera features an enhanced twin-turbocharged 4.0-liter V-8, which trades its previous twin-scroll turbo for a single-scroll design that Porsche says ...
It is the first EcoBoost engine to include twin independent variable cam timing (Ti-VCT), with advertised 10–20% better fuel economy while maintaining the performance of 3.0 L V6s. [ 40 ] [ 41 ] This engine is derived from the 2.0 L Mazda L engine block used by Ford in the North American Focus MK3, but equipped with unique heads, fuel ...
The BMW N20 is a 1.6 and 2.0 L (98 and 122 cu in) turbocharged four-cylinder DOHC petrol engine with variable valve lift and variable valve timing which replaced the N53 (or BMW N52 in some markets) and was produced from 2011 to 2017 by BMW.
It features a twin-scroll turbocharger, BlueDIRECT direct injection, iron-carbon alloy on the cylinder walls to reduce friction, and zircon in the cylinder heads to increase thermal conductivity. [3] The cooling system is also based on the one found in the Mercedes-Benz SLS AMG . [ 4 ]
The engine uses smaller twin scroll type turbos (for reduced turbo-lag), a bespoke Bosch ECU, a modified intercooler configuration, and dry sump lubrication. It produces 730 PS (537 kW; 720 hp) at 5800 rpm [8] and 1,000 N⋅m (738 lb⋅ft) of torque at 2250-4500 rpm. [8]
