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 one twin-scroll turbocharger.
The engine is a 2. 0 litres turbo-diesel cast aluminum block, inline four-cylinder with balancing shafts. 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 at 4,500 rpm with peak torque of 320 N⋅m at 1,400-3,200 rpm. In the 220-configuration it produces 143 kW at 3,800 rpm with peak torque of 400 N⋅m at 1,600-2,400 rpm. The engine weight is 168. 4 kg of the previous 2. 1 litres OM651). 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 torque converter transmission developed by Mercedes Benz....
