The Wärtsilä 46F is the latest in the highly successful marine engine series launched in 1987 with the Vasa 46, as it was then called. Though visually similar to the original Wärtsilä 46, with similar bore and stroke, the Wärtsilä 46F is a new engine with the latest technology applied to all major components. It is packed with new features including common rail injection and scaleable embedded control, for high performance and record-low exhaust emissions, regardless of fuel quality. It is ideally suited to applications which place a premium on optimum space layout, savings in operating and maintenance costs, superior environmental performance and fuel adaptability. The Wärtsilä 46F is our proud and most recent achievement in medium-speed marine engines.
