Propulsion engine B4.5L

inboardauxiliarydiesel

Available for commercial and recreational propulsion applications Based on the proven Cummins B4.5L industrial engine The B4.5L complies with U.S. EPA Tier 3 emissions regulations without the use of aftertreatment Features & Benefits Engine Design: The B4.5L is an in-line, 4-cylinder,16-valve cylinder head, 4-stroke diesel engine, with a robust rebuildable engine block designed for continuous operation. Industry leading engine torque provides excellent vessel acceleration, control and maneuverability. Fuel System: High Pressure Common Rail (HPCR) optimized for best-in-class fuel consumption lowering operating costs. Fuel Pump and Fuel Injectors are designed to operate with alternative fuels such as JP5, JP8 and biodiesel. Electric transfer fuel pump enabling a quick engine start. Includes primary and secondary filters with 10 and 5 microns respectively to provide better protection for the fuel pump and injectors. Cooling system: Single loop with low temperature aftercooler intended for keel cooled (KC) or heat exchanger (HX). The simplicity of the cooling system eliminates the need for a more complex two-loop system, while meeting emissions requirements. For KC applications, the coolant flow and temperature has been optimized to reduce the size of the keel cooler equipped with customer connections. For HX applications, the tube and shell heat exchanger is designed for superior durability and ease of service with minimal maintenance requirements.
