Cummins KTA19-M550 Marine Engine and Spare Parts

The Cummins KTA19-M550 Marine Main Engine is a 6-cylinder inline, four-stroke engine with a displacement of 18.9 liters. It features a bore and stroke of 159 mm (6.25 in) and operates at 2100 RPM. Equipped with a PT Fuel System, turbocharger, and Air-Air intercooler, this marine diesel engine complies with IMO-NOx requirements set by the International Maritime Organization (IMO). It delivers a continuous power output of 550 HP (410 kW) at 2100 RPM, with a maximum torque of 2050 N.m at 1500 RPM.

Hawks Parts provides a variety of cooling options for marine main engines, including heat exchanger cooling and keel cooling. Additionally, we offer complete propulsion systems, including the marine engine, gearbox, shaft, and propeller, providing a comprehensive power system solution for marine applications.

Hawks Parts is committed to offering full life cycle services for all customers, covering design, power system supply, installation, commissioning, after-sales service training, spare parts supply, troubleshooting, and overhaul technical support.

All Cummins marine main engines come equipped with a dry-type exhaust system, comprising a dry-type exhaust manifold and dry-type turbocharger. we also offer upgrading services to convert dry-type exhaust systems into water-cooled exhaust systems, which are often requested for passenger boat projects due to their importance and benefits.

The KTA19-M550 Marine Engine offers several advantages:

  1. Integrated Design: The cylinder block and cylinder head feature an integrated design, reducing the risk of water and oil leakage and minimizing failure rates.
  2. Enhanced Durability: Strengthened cylinder liners and chrome-plated piston rings contribute to improved engine durability, extending its operational life.
  3. Emission Compliance: The engine meets the requirements of China Inland River 1, China Inland River 2, and IMO TIER2 stage emission regulations. It incorporates CMI’s BHT3B supercharger optimized for marine engines, which helps reduce emissions while enhancing reliability.
  4. Fuel Efficiency: High injection pressure, overspeed protection, low-pressure fuel supply, and optimized pipeline design ensure full fuel combustion and high-efficiency energy-saving effects. The equipped ESTC electronic oil timing control valve accurately supplements and adjusts timing, improving combustion smoke color at low idle speed.
  5. Reasonable Exhaust System Design: The exhaust system design of the Chongqing CMI marine engine is rational. Water-cooled superchargers and water-cooled exhaust pipes effectively reduce the engine’s surface temperature, meeting SOLAS safety regulations.
