The Caterpillar 3512 is a high-displacement V12 diesel engine introduced in the late 1970s as part of the company’s 3500 engine family, developed to deliver high-power output for marine propulsion, large industrial equipment, mining trucks, and stationary power generation. Featuring a bore of 170 mm and a stroke of 190 mm, the 3512 shares its core architecture with the 3500-series engines but expands it to a 12-cylinder configuration to provide greater power. Early versions used mechanical unit injection systems, while later models evolved through the 1990s and 2000s with electronic engine management and improved fuel delivery systems to enhance efficiency, monitoring, and emissions performance. 

Many 3512 engines remain in active service thanks to their robust construction, modular design, and ability to be rebuilt multiple times over their operating life and thus, continues to see strong demand for rebuilds and parts support well into the 2020s.
