Marine Engine Model Decoder
Decode any marine engine model number across 34 makers (MAN B&W, WinGD, Wärtsilä, Sulzer, Mitsubishi UEC, Pielstick, Cummins, MTU, Caterpillar, Volvo Penta, MaK, HiMSEN, Hanshin, Akasaka, Bergen, Daihatsu, Niigata, Yanmar and more). Each character of the model number is decoded: maker, cylinder count, stroke, bore, generation, fuel system. Forgiving input: capitalisation, spaces and dashes don't matter.
Formula, assumptions, limits
Each maker uses a structured naming pattern. We strip whitespace and dashes, normalise the case, then match against every maker’s grammar in turn. The first confident match wins. If no parser matches, we compute Levenshtein distance against all known examples and surface the four nearest suggestions.
Coverage: 34 makers spanning two-stroke main propulsion (MAN B&W / Everllence, WinGD, Wärtsilä-Sulzer, Mitsubishi UEC), four-stroke medium-speed (MAN 4-stroke, Wärtsilä W-series, Pielstick, HiMSEN, MaK / Caterpillar, Hanshin, Akasaka, Mitsubishi 4-stroke, Bergen, Daihatsu, Niigata, Yanmar, Doosan, ABC, Stork-Werkspoor, Weichai/Yuchai), four-stroke high-speed and small craft (Cummins, MTU, Volvo Penta, Scania, Yanmar high-speed, Detroit Diesel, John Deere, FPT/Iveco, Perkins), Caterpillar large-bore (3500/3600 series, C-series), and aero-derivative gas turbines (GE LM-series, Rolls-Royce MT-series, Solar Turbines).
Reference guide: See the marine engine model decoder wiki article for the full encyclopedic treatment of each maker’s grammar with worked examples, the complete MAN B&W and Sulzer / WinGD lineage from 1960s mechanical to current dual-fuel / alternative-fuel programmes, exhaustive bore-stroke-cylinder-power matrices, and citations to maker programme guides.
