2-Stroke Low-Speed Marine Engines
In the demanding world of commercial shipping, 2-stroke low-speed diesel engines are the backbone of global trade. Known for their immense power-to-weight ratio and high thermal efficiency, these engines are the preferred choice for large merchant vessels, including tankers, bulk carriers, and ultra-large container ships.
We specialize in providing parts, maintenance, and technical expertise for the industry’s leading low-speed engine designers: MAN B&W, Wärtsilä, and WinGD.
MAN B&W
MAN B&W engines are the most widely used 2-stroke engines in the maritime industry. Their transition from the mechanical MC series to the electronically controlled ME series has set the standard for fuel efficiency and emission compliance.
- ME-C Series: High-performance, electronically controlled engines such as the S50ME-C, S60ME-C, G70ME-C, and the massive G95ME-C.
- MC-C Series: Reliable mechanical engines including the S50MC-C, S60MC-C, and S70MC-C.
- Dual-Fuel (ME-GI / ME-LGIM): Leading the green transition with models like the ME-GI (LNG) and ME-LGIM (Methanol), frequently found on modern gas carriers and container vessels.
Wärtsilä
Wärtsilä’s low-speed engine portfolio (formerly under the Sulzer brand) is renowned for its durability and advanced “Common Rail” technology. While new low-speed designs are now branded as WinGD, thousands of Wärtsilä-branded engines remain in active global service.
- Most Common Models:
- RTA Series: Iconic mechanical engines such as the RTA48T, RTA58T, and RTA96C.
- RT-flex Series: The electronically controlled evolution, including the RT-flex50, RT-flex58, and RT-flex82. These models are celebrated for their smokeless operation and flexible fuel injection.
WinGD (Winterthur Gas & Diesel)
As the successor to Wärtsilä’s 2-stroke technology, WinGD is at the forefront of the X-series engines and low-pressure dual-fuel (X-DF) technology. These engines are designed for maximum efficiency and reduced environmental impact.
- Most Common Models:
- X-Series (Diesel): High-efficiency diesel engines like the X52, X62, X72, and the X92—frequently installed on the world’s largest container ships.
- X-DF Series (Dual-Fuel): The industry leader in low-pressure LNG technology, featuring popular models like the X62DF, X72DF, and X82DF.
- Generation 2.0: Newest versions (e.g., X92DF-2.0) featuring iCER technology to reduce methane slip and improve fuel consumption.
