Powerful new 7-litre engine for power generation

Volvo Penta is introducing a new industrial engine and further expanding its product engine range for power generation. High output yet compact, with rapid response to step loading and low operational costs. These are the most important characteristics of the TAD734GE, an entirely new electronically controlled and highly modern 7-litre diesel engine.
Advanced engine technology
The new TAD734GE is an entirely fresh design featuring the very latest engine technology. Electronically controlled common rail fuel injection in combination with a wastegated turbocharger, air to air charge air cooling and four valves per cylinder provides the basis for high efficiency performance. Precise control over the fuel injection process – fuel quantity and injection timing are adjusted at lightening speed – allows performance characteristics to be optimized to give very fast response to step loading, but with low fuel consumption and low overall exhaust emissions.

Power output for this 7-litre engine is class-leading: 250 kVA prime 50 Hz and 227 kWe standby 60 Hz.

Engineering synergies provide many advantages
The TAD734GE engine has the same electronic engine management system – EMS 2 – as that fitted to Volvo Penta’s 9, 12 and 16-litre engines. It is a particularly user-friendly system based on CAN-bus technology. The customer can choose to use Volvo Penta’s engine instruments and control equipment or to connect his own control system via the interface provided in the EMS.

Dual speed switching between 50 and 60 Hz is standard on this new TAD734GE, as in all Volvo Penta industrial engines designed for power generation.

On delivery, all major equipment – cooling system, air intake system, engine ECU, - is premounted onto the engine in order to give reduced assembly time for the set builder.

EU emissions Stage 2
Modern engine technology means low exhaust emissions, and the TAD734GE is developed and certified for EU Stage 2, also meeting the standards for ½ TA-luft.
