The Caterpillar 3612 is a large-bore, medium-speed industrial diesel engine developed as part of the company’s 3600 engine family. Introduced during the 1980s, the 3612 was designed for continuous heavy-duty service in marine propulsion, oil and gas operations, and large stationary power plants. The engine features a bore of 280 mm and a stroke of 300 mm. The 3608 was most commonly used in large marine vessels, offshore platforms and pipeline compressor stations. Like other engines in the 3600 series, it used direct unit fuel injection, turbocharging, and aftercooling, emphasizing robust mechanical design. The 3612 engine would evolve into a gas variant as well with the introduction of the G3612 engine. 

Production of the 3612 gradually declined in the 2010s as newer electronically controlled and emissions-compliant engines replaced many of its roles. Despite this, many 3612 engines remain in service today.
