Cummins Marine Engine KT38-M900 And Spare Parts

The Cummins KT38-M900 Marine Main Engine is a V Type 12-cylinder, 38-liter four-stroke engine with a bore and stroke of 159 mm (6.25 in). Operating at 1800 RPM, the KTA38-M900 Marine Main Engine is equipped with a CMS PT Fuel System, a turbocharger, and a Water-Air intercooler, ensuring compliance with IMO-NOx requirements set by the International Maritime Organization (IMO). It delivers a continuous power of 900 HP (671 kW) at 1800 RPM.

Hawks Parts offers both heat exchanger cooling and keel cooling options for marine main engines, based on standard CCEC marine main engines. Additionally, We provide complete propulsion systems, including the marine engine, gearbox, shaft, and propeller, offering a comprehensive power system solution.

Hawks Parts is committed to providing 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 CCEC marine main engines come equipped with a dry-type exhaust system, including a dry-type exhaust manifold and dry-type turbocharger. Hawks Parts also offers upgrading services for water-cooled exhaust systems, modifying dry-type exhaust systems into water-cooled exhaust systems, which are often requested for passenger boat projects due to their importance and benefits.

The advantages of the KTA38 M900 marine engine

  • The cylinder block is integrated with the cylinder head, which reduces failure rates and prevents oil and water leakage. The use of chrome-plated piston rings and strengthened cylinder liners improves durability and extends engine life.
  • The engine meets the emission requirements for China Inland River 1, China Inland River 2, and IMO Tier 2 stage. It also adopts the BHT3B turbocharger, optimized by Chongqing CMI specifically for marine engines. The engine is designed to reduce emissions and improve reliability.
  • It can achieve energy savings with high efficiency and high-efficiency thanks to its high injection pressure and overspeed protection. The ESTC electronic timing control valve equipped with the device can precisely adjust and supplement the timing, and improve the color of the combustion smoke at low idle speeds.
  • The exhaust system design of the Chongqing CMI Marine Engine is reasonable. Water-cooled superchargers and water-cooled pipes can reduce the surface temperatures of the engine to meet SOLAS safety requirements.
