The D7E engine has long service intervals, which contributes to low mainten ance costs.

Efficient combustion is achieved through measures such as high boost pressure from the turbocharger.

Features• The engine offers a very wide torque range and responds alertly to the accelerator, resulting in excellent driveability.• Electronic engine management – EMS – with precise fuel injection promotes efficient combustion and low emissions with

the help of SCR technology.• Electronic fuel injection with precise control of the amount of fuel injected and injection timing results in low exhaust emissions

and good fuel economy.• Exhaust treatment with SCR technology means the engine meets the EU’s tough environmental standards according to

Euro 5 and EEV.• Disruptions in the exhaust treatment system are shown in the display in the instrument panel.

Power and EfficiencyThe Volvo D7E290 is a 7.1-litre, in-line six-cylinder diesel engine with a power output of 290 bhp, equipped with a turbocharger and intercooler. The engine meets the EU’s exhaust emission standards according to Euro 5 and EEV.

290 bhp, 7.1-litre diesel engineThe Volvo D7E engine is equipped with updated systems for fuel injection and the latest-generation engine management system, EMS. A particularly wide torque range contributes to excellent driveability.

Electronic engine management and extremely precise common rail fuel injection promote accurately controlled fuel injection. This together with high boost pressure from the turbocharger, high injection pressure and optimisation of the fuel injector nozzles in the combustion chamber leads to efficient combustion.

The efficient combustion process together with after-

treatment of the exhaust gases using SCR (Selective Catalytic Reduction) technology means this engine is environmentally optimised, approved according to the Euro 5 emission norms. What is more, emission levels are below the limit for EEV (Enhanced Environmentally friendly Vehicle) which imposes even higher demands, for instance requiring even lower levels of particulate emissions.

The engine is very smooth and quiet owing to its design. The timing mechanism is surrounded by a steel panel with a cast iron cover. The Volvo D7E engine has long service in-tervals, which contributes to low maintenance costs.

Approved for today’s and tomorrow’s environmental standardsThanks to its high efficiency rating, the D7E has low emissions. The exhaust gases are further cleaned using SCR (Selective Catalytic Reduction) technology. This means that an additive known as AdBlue is injected into the exhaust gases before they pass through an SCR catalytic converter where the nitrogen oxide is converted into harmless nitrogen gas and water vapour. As a result, the emissions are so low that the engine meets all the EU’s emission requirements as per Euro 5 and EEV (Enhanced Environmentally friendly Vehicle). Since exhaust treatment takes place without affecting the engine’s combustion process, this also means that fuel consumption is not affected.

Precise injection for efficient fuel utilisationIn the D7E, injection takes place using common rail techno-logy. The fuel is injected under high pressure through a common feed rail. The engine’s various functions are controlled electronically with the help of Volvo EMS (Engine Management System), which means that pressure and timing can be monitored and regulated with immense precision. As a result, combustion can always be optimised on the basis of the current driving conditions, thus contributing to excellent driveability. The engine control unit is linked with the vehicle’s own electronic system. This has the added advantage of providing advanced scope for diagnostics and fault-tracing. Disruptions in the exhaust treatment system are shown in the display in the instrument panel.

Components and lubrication system dimensioned for long service lifeThe cylinder block and cylinder head are made of cast iron, which gives a sturdy yet light framework for the engine. The engine’s moving parts are all built to withstand long-term strain. The lubrication system in the D7E guarantees effective lubrication and cooling of all the engine’s systems. The gear-driven oil pump ensures secure oil flow under all operating conditions. A separate oil system for piston cooling guaran-tees cooling all the way from idling speed. All this together gives the D7E high reliability and a long service life.
