Product catalog summary

General Specifications
The K38-M and KTA38 engines are V-12 cylinder, 4-stroke diesel engines designed for marine propulsion and auxiliary applications. They feature turbocharged and aftercooled aspiration with a displacement of 38 liters. The engines rotate counterclockwise when facing the flywheel and utilize a Pressure Time (PT) fuel system. Dimensions and weight vary based on configuration, with an overall length of 2152 mm, width of 1462 mm, height of 2083 mm, and weight of 4218 kg.

Power Ratings
The engines offer various power outputs ranging from 559 kW to 1119 kW, with engine speeds between 1600 and 2050 RPM. They are rated for continuous, heavy-duty, medium continuous, and intermittent operations. Fuel consumption varies by model and speed, with compliance to ISO 8178 standards for emissions.

Features and Benefits
The engines are designed with a low profile for easy installation and service. They include replaceable wet cylinder liners, a Cummins PT fuel system with optional CENTRY electronics, and a cooling system that can be keel cooled or use a plate heat exchanger. The exhaust system features a dry manifold with water shielding, and the air system includes marine-grade filters. The lubrication system offers standard or high-capacity oil pans, and the engines come with a 24V electrical system.

Certifications
The engines comply with IMO Tier 1, IMO Tier 2, or EU Stage 3a emissions regulations. Certificates of compliance are available from the U.S. EPA and Lloyd’s Register of Shipping. They are designed to meet SOLAS requirements.

Optional Equipment
Optional features include the CENTINEL oil management system, prelub starter, direct mounted front power take-off, duplex lube filtration, and engine room and pilot house panels with analog gauges.

Fixed Speed Ratings
Fixed speed models offer power outputs from 634 kW to 1007 kW at speeds of 1500 RPM (50 Hz) and 1800 RPM (60 Hz). They are rated for prime operations with fuel consumption based on ISO 8178 D2 standards.
