The very first Wartsila gas engine (the Wärtsilä Vasa 32GD) was introduced in 1987. It was a gas-diesel engine with direct high-pressure gas and diesel fuel injection. The first spark-ignited gas engine concept was initiated in 1992 and the first engine was released in 1993. The Wartsila Vasa 32-based Wartsila Vasa 34SG spark-ignited gas engine family appeared on market in 1995. One year later Wartsila Vasa 32DF dual-fuel engine was released. The newest 34SG engine basing on a new frame of Wartsila 32 heavy fuel oil diesel engine was presented in 1999. The Wartsila 34SG is four-stroke spark-ignited lean-burn turbo-charged engine with ported gas admission and pre-chamber ignition system. Engine design combines well proven gas engine technology with recent developments in diesel engines. The Wartsila 20V34SG medium speed engine in 20-cylinder V-configuration with mean effective pressure at the level of 20 bar gives a total mechanical output power up to 9000 kW accompanied with 44.3% electrical efficiency. The engine can operate with full power at high altitude and hot and dry ambient conditions. All its components were designed to provide reliability, good performance, high efficiency, long maintenance-free intervals and long lifetime of engine. A modular ergonomically designed system enables easier maintenance access and shorter service time. The Wartsila 20V34SG is dedicated to Wartsila gas power plants designed for optimum performance. Gas power plants are based on engines operating on dual-fuel (gas/diesel) or natural gas. The typical power range is 4 to 150 MW and gas power plants can also provide combined heat and power option. The Wartsila gas power plants can operate continuously or as peak load electricity generation unit and can operate in parallel to the grid or in island mode. Power plants are a power source for industry, for local utilities or for public electricity. This paper will present technical specification of the Wartsila 20V34SG. The main technical data of engine components and technology will be described. Finally, some typical applications of the Wärtsilä 20V34SG will be shown. The newest power plant concept, an one-engine based compact power plant "GasCube", will be also presented in this paper.
