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 [51] and hybrid turbochargers. A similar phenomenon that is often mistaken for turbo lag is the boost threshold. This is where the ...
Twin-turbo is a type of turbo 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 independent piping.
Whilst the N54 used a twin-turbo arrangement, the newer N55 uses only a single twin scroll turbocharger. [ 3 ] [ 4 ] Valvetronic (variable valve lift) [ 5 ] is claimed to improve throttle response, low-rev torque, exhaust emissions and to reduce fuel consumption by 15%.
They use dual overhead camshafts with 4 valves per cylinder, feature twin-scroll turbochargers, [2] and have particulate filters installed. M264 engines also have intake variable valve timing and a 48V system that powers the electric auxiliary compressor and integrated starter alternator.
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 ...
Single twin-scroll with air-to-liquid intercooler: Fuel system: Bosch HDEV5/HDEV5 EVO 200 bar (2,901 psi) central high-pressure Gasoline direct fuel injection. One direct injector per cylinder fed by an Bosch engine-driven high-pressure fuel pump (B48 non-TU) Bosch HDEV6 350 bar (5,076 psi) central high-pressure gasoline direct fuel injection ...
In contrast to the M178, this version of the engine uses wet-sump lubrication. In the C63 and GLC63 applications, the turbos are single-scrolled, whereas in E63 and S63 are twin-scrolled and different exhaust manifold. The twin-scroll application also features cylinder deactivation. [6]
The engine is a 2.0 litres (1,950 cc) turbo-diesel cast aluminum block, inline four-cylinder with balancing shafts. [3] It has a single turbo and its cylinder walls are lined with slippery Nanoslide, an iron-carbon coating that cuts friction. In the 200-configuration it produces 110 kW (150 PS; 148 hp) at 4,500 rpm with peak torque of 320 N⋅m ...
