Cummins KTA19-M470 Marine Engine and Spare Parts

The Cummins KTA19-M470 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 1800 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 470 HP (351 kW) at 1800 RPM, with a maximum torque of 1950 N.m at 1500 RPM.

Hawks Parts offers a range of cooling options for marine main engines, including heat exchanger cooling and keel cooling. Additionally, we provide complete propulsion systems, including the marine engine, gearbox, shaft, and propeller, as a complete power system solution for marine applications.

Hawks Parts is committed to providing full life cycle services for all customers, encompassing 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, which includes a dry-type exhaust manifold and turbocharger. we also offers 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-M425 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.
