context_page_description: List of Volkswagen Group diesel engines. The compression-ignition diesel engines listed below are currently used by various marques of automobiles and commercial vehicles of the German automotive concern, Volkswagen Group, and also in Volkswagen Marine and Volkswagen Industrial Motor applications. All listed engines operate on the four-stroke cycle, and unless stated otherwise, use a wet sump lubrication system, and are water-cooled.
  Previous Volkswagen Group Diesel engines are in the list of discontinued Volkswagen Group diesel engines article.
context_section_description: A world first. Wholly developed by quattro GmbH, AUDI AG's private high-performance specialist subsidiary, and built at Audi Hungaria Motor Kft. in Győr, Hungary, this Turbocharged Direct Injection (TDI) V12 engine is a road-going development of the unit in the 24 Hours of Le Mans winning Audi R15 TDI. It features common rail direct injection, and includes the same cylinder bore and piston stroke as the latest 3.0 V6 TDI CR. This engine has created the most powerful sport utility vehicle (SUV) in its class - the Audi Q7 V12 TDI quattro.
  identification
  parts code prefix: 05A
  engine configuration & engine displacement
  60° V12 engine, Turbocharged Direct Injection (TDI) turbodiesel; 5,934 cc (362.1 cu in); bore x stroke: 83.0 mm × 91.4 mm (3.27 in × 3.60 in), stroke ratio: 0.91:1 - undersquare/long-stroke, 494.5 cc per cylinder; 90 mm (3.54 in) cylinder spacing; 17 mm (0.67 in) cylinder bank offset; compression ratio: 16.0:1; two oil coolers (one: water/oil, the other: air/oil); four coolant radiators; water-cooled alternator
  cylinder block & crankcase
  GJV-450 compacted vermicular graphite cast iron (GJV/CGI); nodular graphite reinforced cast iron bedplate frame with seven main bearings and four bolts per bearing, die-forged chrome and molybdenum steel alloy crossplane crankshaft, diagonally fracture-cracked forged connecting rods, aluminium forged Mahle pistons, two-part cast aluminium alloy baffled oil sump
  cylinder heads & valvetrain
  composite lower section made from low-pressure die cast aluminium alloy with integrated intake and exhaust ports, middle section for guiding engine oil flow, and the top section is a pressure-cast ladder frame for the overhead camshafts; four valves per cylinder, 48 valves total, low-friction roller finger cam followers with automatic hydraulic valve clearance compensation, double overhead camshaft - the exhaust camshafts driven from the flywheel side via a two-stage chain drive utilising three 3/8" simplex roller chains, and the inlet camshafts driven from the exhaust camshafts by gears at the front of the engine; two unequal-length swirl-inducing switchable inlet ports, siamesed unequal-length exhaust ports
  aspiration
  two air filters, two hot-film air mass meters; 'biturbo': two water-cooled turbochargers with electrically controlled Variable Turbine Geometry (VTG) (one turbo per cylinder bank) and an electronically regulated boost pressure of up to 2.6 bar (38 psi), two all-alloy side-mounted intercoolers; cast alloy intake manifold with dual adjustable turbulence flaps
  fuel system & engine management
  Bosch 2,000 bar (29,010 psi) common rail (CR) (one rail per cylinder bank) direct injection: with two chain-driven high-pressure fuel pumps, fuel cooler for return line, twelve combustion chamber-sited eight-hole (0.12 mm (0.0047 in)) piezo injectors with multi-pulse injection (up to five injection operations per piston cycle, including pre- and post- ignition injection); two Bosch EDC electronic engine control units (ECUs) working on the 'master and slave' concept; water-cooled vacuum-actuated exhaust gas recirculation (EGR) with up to 50% recirculation rate at partial engine load; European Euro5 emissions standard compliant
  exhaust system
  double flow exhaust pipes with two catalysts and two diesel particulate filters (DPF); two lambda sensors, two exhaust gas temperature sensors
  dimensions
  length: 684 mm (26.9 in) (just 166 mm (6.5 in) longer than the V8 TDI),
  DIN-rated power & torque output, ID code
  368 kW (500 PS; 493 bhp) at 4,000 rpm - 62.0 kW (84.3 PS; 83.1 bhp) per litre; 1,000 N⋅m (738 lbf⋅ft) at 1,750-3,000 rpm — CCGA
