Engine Information

Engine Family: Wärtsilä 32 Marine Engine

Engine Type: Dual Fuel Engine

Description

The Wärtsilä 32 is a medium‑speed, four‑stroke marine diesel engine widely used for both main propulsion and auxiliary power generation. Designed for high reliability and fuel‑efficient operation, the 32‑series has become one of Wärtsilä’s most successful engine platforms in commercial shipping, offshore vessels, ferries, and specialized industrial applications.

With a cylinder bore of 320 mm, modular construction, and multiple cylinder configurations, the Wärtsilä 32 offers flexible installation options and scalable power output for vessels requiring dependable performance under continuous load. Its long maintenance intervals, low specific fuel consumption, and compatibility with HFO, MDO, and dual‑fuel variants make it a preferred choice for operators seeking operational efficiency and lifecycle cost reduction.

Compared to the larger Wärtsilä 34 and 38 engines, the 32‑series provides an optimal balance between power density, fuel economy, and footprint, making it suitable for medium‑power propulsion systems and high‑demand auxiliary generator sets.
