The Mercedes-Benz OM 654 is a family of inline-four cylinder automobile diesel engines introduced by Mercedes-Benz in 2016. This is one of the most powerful 2-liter inline-4 cylinder diesel engines with two twin-scroll turbocharger.[2]

OM 654

The engine is a 19501NaN1 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 1100NaN0 at 4,500 rpm with peak torque of 320Nm at 1,400-3,200 rpm. In the 220-configuration it produces 1430NaN0 at 3,800 rpm with peak torque of 400Nm at 1,600-2,400 rpm. The engine weight is 168.4kg (371.3lb) (a 17% improvement over the 202.8kg (447.1lb) of the previous 21431NaN1 OM651).[4] [5] Also, the engine consumes 13% less fuel than its predecessor. It is planned that it will feature across the entire Mercedes-Benz range of cars and vans. Both the 200d and 220d are mated to a 9 speed dual clutch transmission developed by Mercedes Benz.

OM 654q

A transverse version of OM654 that can be mounted in smaller cars and front-wheel-drive vehicles.[6] Mercedes-Benz OM 654q 4-cylinder diesel complies with Stage 2 RDE, certified to Euro 6d

OM 654 M

With the OM 654 M, Mercedes claims to deliver the worldwide first diesel engine with integrated starter generator. The revised two-liter turbodiesel four-cylinder was given a new crankshaft for electrification, increasing the displacement by 43 to 1,993 cubic centimeters. At the same time, the injection pressure will be increased from 2,500 to 2,700 bar. The maximum power is now 265 hp, the maximum torque 550 Newton meters. On the exhaust side, a NOX storage catalytic converter, particle filter and two SCR catalytic converters have been retrofitted.
