Volvo D16: The heart of the world’s most powerful truck

It was already powerful, now it is the most powerful in the world. Enter the Volvo D16G – the beating heart of the new Volvo FH16.

With 700 horsepower and 3,150 Nm of torque, Volvo’s newest 16-litre engine sets a new benchmark for the truck industry. This is the first time ever that a commercially-produced truck has been launched with such a powerful engine, designed for the very heaviest and most demanding of haulage assignments.

40 extra horsepower, 40 per cent lower emissions
The new engine is a further development of Volvo’s current D16 engine that produces 660 hp. In addition to an extra 40 horsepower and higher torque, the new engine produces cleaner exhaust gases. The new 16-litre engine is certified for the new Euro 5 European emission requirements that come into force on October 1st 2009, which means that oxides of nitrogen emissions are now 40 per cent lower.

The Volvo D16G is also available at Euro 5 with new 600 hp and 540 hp variants.

Optimised combustion promotes higher efficiency rating
Despite the higher power, fuel consumption levels remain as economic as the current engine generation. Through a number of measures - including redesigned pistons - Volvo’s engineers have optimised the combustion process and met demands for high performance combined with efficient fuel utilisation, low emissions and long lifetime. Both maximum power and maximum torque span a wider rev range than before, contributing to excellent driveability. The engine now also features a new oil thermostat that has a favourable effect on fuel consumption.

Quieter idling
The noise level during idling has now been lowered by 2dB(A). With the help of pre-injection, where a small amount of fuel is sprayed into the cylinder, the result is a gentler combustion sequence and a far lower noise level.

Effective exhaust cleaning
Another important change is that in the two most powerful engine variants is a new and larger exhaust after-treatment system. Since the system can handle a larger flow of exhaust gases, counter-pressure is reduced and power losses are minimised. A larger-capacity system also results in better cleaning capacity. As with the current model, the Selective Catalytic Reduction (SCR) system is used, taking effective care of harmful emissions.

EPG or VEB+
The Volvo D16G is equipped with a new, electronically-controlled exhaust brake (EPG) as standard with an output of 230 kW. Electronic control makes it possible to reduce the number of moving parts, promoting simpler operation, higher reliability and lower weight.

There is also the option of the Volvo Engine Brake (VEB+) with 425 kW maximum braking effect.
