Engine, description
D12D is a straight six-cylinder, four-stroke, turbocharged diesel engine with direct injection and intercooler, as well as wet,
replaceable cylinder liners. The engine is equipped to meet governing legislation according to Tier 3/stage IIIA for exhaust
emissions.
D12D uses V-ACT (Volvo Advanced Combustion Technology) and gas split inspection, optimized air handling, and
turbocharger with wastegate. Electronically controlled IEGR (Internal Exhaust Gas Recirculation) lowers the content of NOX
and reduces emissions without aftertreatment of exhausts. All electronic functions in the engine are controlled by Volvo's
engine management system EMS2.
Cylinders are numbered in sequence beginning farthest from at the flywheel. Firing order: 1-5-3-6-2-4. The engine's
rotational direction is counter-clockwise seen from the flywheel.
