auxiliarydieselprofessional vessel

The 3512E marine propulsion engine is now available in a wide range of ratings that meet U.S. EPA Tier 4 Final and IMO III marine emissions regulations. As the commercial marine industry adjusts their operations to meet U.S. EPA Tier 4 Final and IMO III emissions standards, Caterpillar Marine has introduced a solution built to maximize performance while meeting regulations. Caterpillar's combination of a fuel-efficiency-optimized engine and a selective catalytic reduction (SCR) aftertreatment system is a solution that not only reduces NOx emissions, but can also lower a customer's owning and operating costs in the process. Utilizes SCR Technology to enable U.S. EPA Tier 4 Final emission regulations compliance while lowering operational costs, IMO III emissions compliant Highest efficiency mixing and control to lower operational costs, extends emissions useful life, ensures compliance, flexibility regarding urea quality Advanced engine combustion design process utilizing optimum configurations and cylinder geometry for maximum engine efficiency AIR INLET SYSTEM Corrosion-resistant aftercooler core CONTROL SYSTEM Dual A5 engine control modules with electronic unit injection and low pressure fuel system EXHAUST SYSTEM Dual turbochargers with water-cooled bearings and heat shields GENERAL Vibration damper and guard Meets SOLAS regulations FUEL SYSTEM Duplex Fuel and Oil Filtration COOLING SYSTEM Auxiliary fresh water pump Gear Driven, centrifugal jacket water pump with 40% more capacity
