The Wärtsilä 46TS-DF is a four-stroke dual fuel engine generating set offering exceptional output, efficiency, and flexibility. Evolved from a long line of proven and reliable Wärtsilä engines with millions of running hours, this large-bore engine has a 2-stage turbocharging system that enables superior performance, even in challenging environmental conditions.
Wärtsilä 46TS is designed for balancing renewables and to operate cost-efficiently on baseload. The engine’s improved output and efficiency save fuel and costs while keeping emissions to a minimum. Its fast-starting capability with unlimited starts and shutdowns maximise your revenue streams. The DF technology allows instant switching to alternative fuels, should price instability or delivery challenges affect the use of the primary fuel. Wärtsilä 46TS is based on futureproof technology that can run on sustainable fuels in the future.
