The Volvo D5[1] is a type of turbocharged diesel engine developed by Volvo Cars for use in its passenger cars. The D5 engine is based on Volvo Modular engine.[2]

History[edit]

Volvo D5 engine D5244T15 (Euro 5), in 2015 model year Volvo XC70

It is an all aluminium five-cylinder engine with 20 valves and double overhead camshafts. In all but one late version it has a VGT turbocharger of the type VNT (variable nozzle turbine), common rail direct injection and cooled exhaust gas recirculation (EGR).

There are three generations of D5 engines:

  • The first generation was introduced in 2001.
  • The second generation was introduced in 2005. The second generation got a slight reduction in stroke and has a reduced compression ratio, a water-cooled VNT turbocharger with a bigger compressor and an electric servo motor to adjust the vanes, an improved EGR system, a throttle valve, revised intake and exhaust ports and a newer generation of common-rail direct injection with improved injectors.[3]
  • The third generation was introduced in 2009. The third generation got a further reduction in compression ratio, a two-stage turbo system (D5244T10), an improved exhaust gas recirculation (EGR) system, revised intake and exhaust ports and a newer generation of common-rail direct injection with higher pressure and piezoelectric injectors.

Volvo has a special version of the D5 for use in the C30, S40, V50 and C70 models that produces 180 hp (134 kW) and 400 N⋅m (295 lb⋅ft) of torque (reduced to 350 N⋅m (258 lb⋅ft) with automatic transmission). The engine compartments of these cars are smaller so among other things the engine has a different air intake system, different exhaust system, smaller charge air cooler and a smaller radiator.

In 2009 Volvo, in conjunction with Polestar, launched software upgrades for many of its D5 engines.[4] These upgrades have no impact on official emission or fuel consumption figures, but produce power and torque gains of typically a little over 10%. The first engine to have such an upgrade available was the D5244T4, and the upgrade increased the torque from 400 to 450 N⋅m (295 to 332 lb⋅ft), and power from 185 to 205 PS (136 to 151 kW). The same upgrade was available for the mechanically-identical D5244T5. Similar upgrades have since been launched for later engines. [5]

Marine engine[edit]

The D5244T is also offered as a marine engine by Volvo Penta under the name D3. The marinised engine is in large parts identical to D5244T. This includes crankshaft, pistons, camshafts, valves, cylinder block, cylinder head, turbo, injectors and the high pressure pump. The D3 ECU has a modified software, which e.g. gives a modified torque suited for marine applications and has a simplified starting sequence. The hardware differences between D5244T and D3 are: a water-cooled intercooler, a water-cooled exhaust manifold, a heavier monolithic crankwheel, a seawater-pump and a heat exchanger. The output is 110 hp (82 kW) at 3,000 rpm, 130 hp (97 kW), 160 hp (119 kW), 190 hp (142 kW), 220 hp (164 kW) at 4,000 rpm and it is coupled to a duoprop I/O system.

Note: 'D5' is branding. All these engines share the five-cylinder block, although not all consistently used the 'D5' badge over time. This is due to changes in hardware and the specific model the engine was deployed in. E.g. On the S60 -05 range, the D5244T was labelled 'D5', and subsequently the D5244T5 was labelled '2.4D' as a (software) detuned version of the D5244T4 'D5' on the 05-09 range.

Successor[edit]

In autumn of 2013 the new Volvo Engine Architecture was introduced. The 5-cylinder D5 was phased out along with the V70/XC70 and first generation XC60.
