3512C HD

3512C High Displacement Propulsion Engine

3512C HD High Performance

DESCRIPTION

The Cat 3512C marine propulsion engine makes your investment work harder. Through a wide range of available power 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 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

Making Your Investment Work Harder

Uses advanced predictive modeling software to select best nozzle configurations and combustion cylinder geometry, Stainless steel exhaust manifold and turbo heat shields, Closed crankcase ventilation system, Dual camshafts, Reduced aftercooler heat load for smaller heat exchanger requirements

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, Uses K-factor injector to align with predictive model analysis, Better electronic injection control using crank timing vs. cam timing, EPA Marine Tier 3/IMO Tier II Emissions Compliant, Lower IMAT = Lower NOx

Improving Workforce Efficiency

Electronic governing (A4 ECU), Instrument panel shipped loose with Color Marine Power Display (MPD), Cold mode start strategy, Programmable low idle, Optional marine alarm and protection system

Fully Integrated Marine Power Solution

Single-source support, Caterpillar warranty for all factory packaged components, Industry-leading one-year warranty on parts
