3512C
DESCRIPTION
The Cat 3512C marine propulsion engine makes your investment work harder. Through a wide range of available power ratings (including High Displacement ratings), no required aftertreatment technology, and nominal rated BSFC fuel consumption - it will drive down your total cost of ownership. With a redesigned piston bowl shape to improve combustion, and improved fuel delivery, this engine is IMO II or China Stage II emissions compliant and committed to sustainable environmental development. Single-source support, the Caterpillar warranty, and industry-leading one-year warranty on parts make the 3512C a fully integrated marine power solution.Driving down total cost of ownership
A wide range of power ratings available, No aftertreatment technology required, Fuel consumption nominal rated BSFC
COMMITTED TO SUSTAINABLE DEVELOPMENT
Modified piston bowl shape to improve combustion and reduce emissions. Better electronic injection control using crank timing vs. cam timing, IMO Tier II Emissions Compliant, Lower IMAT = Lower NOx
IMPROVING WORKFORCE EFFICIENCY
Electronic governing (A6 ECU), Instrument panel shipped loose with color Marine Power Display (MPD), cold mode start strategy, programmable low idle, optional marine alarm and protection system
