The M133 is based on the M270 engine but has been extensively revised by AMG. [2] 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]
A twin-scroll turbocharger uses two separate exhaust gas inlets, to make use of the pulses in the flow of the exhaust gasses from each cylinder. [34] In a standard (single-scroll) turbocharger, the exhaust gas from all cylinders is combined and enters the turbocharger via a single intake, which causes the gas pulses from each cylinder to ...
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 ...
The twin-scroll turbocharger uses 2 sets of exhaust duct to turn 1 turbine wheel, with cylinders 1–3 and 4–6. [9] The engine management system is Bosch MEVD 17.2, and compatible fuels are ROZ (RON) 91–98 octane (minimum RON 95 is recommended), [ 10 ] [ 11 ]
It features a higher compression ratio than its predecessor (10.1:1 vs 9.3:1), with the exception of the Maverick, [53] along with a twin-scroll turbocharger and fuel and oil systems upgrades, as well as a redesigned block and cylinder head. [54] This new engine will deliver more low-end torque than its predecessor.
For the facelifted 2013–2014 Genesis Coupe, the engines got upgraded with a new twin-scroll turbocharger, compression ratio is 9.0:1 and the newer version now producing 260–264 PS (191–194 kW; 256–260 hp) at 6,000 rpm and 36 kg⋅m (260 lb⋅ft; 353 N⋅m) of torque between 2,000 and 4,500 rpm on 91 RON/87 octane gasoline, and 275–279 ...
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.
