The Volvo D12D, a 12.1 - liter in - line 6 - cylinder diesel powerhouse, is a marvel of engineering. It features direct injection and intercooling, with a compression ratio of 18.1:1 for models like the 420 hp, 460 hp, and 500 hp variants.
This turbocharged engine, with a bore of 131 mm and a stroke of 150 mm, meets strict Tier 3/Stage IIIA emissions standards. It has a fully - overlapping cylinder head with 4 valves per cylinder and an overhead camshaft, ensuring optimal air - fuel mixing.
