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 a single twin-scroll turbocharger.[2]
OM 654
The engine is a 2.0 litres (1,950 cc) turbo-diesel cast aluminum block in line four-cylinder with balancing shafts.[3] It has a single turbo and 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 (236 lbf⋅ft) at 1,400-3,200 rpm. In the 220-configuration it produces 143 kW (194 PS; 192 hp) at 3,800 rpm with peak torque of 400 N⋅m (295 lbf⋅ft) at 1,600-2,400 rpm. The engine weight is 168.4 kg (371 lb) (a 17% improvement over the 202.8 kg (447 lb) of the previous 2.1 litres (2,143 cc) 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 an 220d are mated to a 9 speed dual clutch transmission developed by Mercedes Benz.
Applications
OM 654q
It is a version of OM 654 placed transversely (quer). This makes it possible to mount this engine in smaller models of cars and front-wheel-drive vehicles.[6][7]
