3512C Tier 3

3512C Tier 3 Marine Propulsion Engine

3512C Tier 3 Commercial Propulsion Engines

DESCRIPTION

The 3512C High Displacement marine engines are now available in a wide range of ratings that meet EPA Marine Tier 3 and IMO II regulations without any additional aftertreatment. These new propulsion, auxiliary, and DEP engines, designed and built from the current 3512C and 3516C platforms, have minimal dimensional and weight changes in comparison. Owning and operating costs are also very similar. For the specific fuel consumption of each rating please refer to the performance data. New features include stainless steel exhaust heat shields, closed crankcase ventilation system, and EPA Tier 3 compliance.

Power Range

1340-2366 bhp (1000-1765 bkW)

Speed Range

1600-1800 rpm

Emissions

EPA Tier 3, IMO II

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
