Volvo Penta launches new power generation engines

High power-density diesel models offer up to 800 kVA for genset market

Volvo Penta has announced the launch of two new diesel engines – one of which has the highest power density engine per liter of displacement in its class.

A statement from the Volvo group company issued in conjunction with its presence at the Middle East Electricity exhibition in Dubai, where the engines are on display, said the TWD1645GE and TWD1644GE engines extend the company’s competitive range and reinforce its commitment to international genset customers.

Volvo Penta is taking a significant step forward by adding new technology and upgraded features to its new power generation engines, the statement added. The 16-litre TWD1645GE has been designed to produce up to 10% more power compared to previous models, offering what the company claims is one of the global class leading independent power sources. Its switchable rpm settings mean that it can be used anywhere in the world, Volvo Penta added.

“This is an exciting move for us to be launching the highest power density engine in its class,” said Giorgio Paris, head of Volvo Penta’s industrial segment. “We are setting a new standard in power generation with our market-leading offer. The engine comes equipped with our latest features, which enable us to deliver the most power per litre displacement of any 16-litre engine on the market.”

The TWD1645GE produces up to 800 kVA at 1800 rpm (60 Hz), and up to 770 kVA at 1500 rpm (50 Hz.). Its sister model, the TWD1644GE produces up to 752 kVA at 1800 rpm, and up to 717 kVA at 1500 rpm. Both are calculated with 94% generator efficiency.

“We have achieved this level of market-leading power density by advancing our technology and adding new features,” added Krikor Abraham, Volvo Penta’s product manager for the power generation segment. “We are able to leverage more power out of the engines, and customers will see a range of benefits.”

According to the statement, the new 16-litre engines feature dual stage turbo-chargers and new high grade steel pistons, for excellent power density; optimised combustion with electronic high-pressure unit injectors, resulting in high fuel efficiency and low exhaust emission levels; upgraded wiring harness, for optimum insulation in harsh environments; a two-circuit cooling package; and an advanced engine control system.

The engine can be used for prime power, in locations such as construction sites where there is no electricity grid supply, and as standby power, for sites such as hospitals which require back-up electricity supply in the event of normal power failure.

Volvo Penta’s TWD1645GE and TWD1644GE feature the same engine base as the rest of the 16-litre diesel family, allowing for ease of installation and maintenance. Furthermore, with the new and upgraded features, customers can be assured of a low total cost of ownership through the engines’ excellent fuel economy. The statement added that smooth operation is enabled by low noise and reduced vibration, and the engines are equivalent to EU Stage II levels, which means exhaust emissions are minimised for better environmental care.

“These new models’ excellent power-to-size ratio means that they are compact, flexible, have good load acceptance, and can be used in all types of applications,” added Abraham. “Customers can power their businesses with our new power output, and our global footprint means that we can supply the same engine to anywhere in the world with the same service support and aftermarket care.”
