Cummins KTA38-850 Marine Engine and Spare Parts

Cummins KTA38-850(1800 RPM) Marine Main Engine is V Type 12-cylinder, 38-liter four-strokes engine with 159 mm (6.25 in) bore and 159 mm (6.25 in) stroke. KTA38-M0-850 Marine Main Engine equipped with CMS PT Fuel System, comes with turbocharger, this marine diesel engine complies with IMO-NOx requirements of the International Maritime Organization (IMO). The continuous power at 1800 RPM of CCEC KTA38-M0-850 Marine Main Engine is 850 HP (634 kW). The maximum torque of the engine at 1500 RPM is 3587 N.m.

Based on standard CCEC marine main engines, Hawks Parts provides both heat exchanger cooling and keel cooling marine main engines, we also provide a complete propulsion system that includes a marine engine, gearbox, shaft, and propeller as a complete power system. Hawks Parts provides full life cycle services for all our customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, and from troubleshooting to overhaul technical support.

All CCEC marine main engines come with the dry type exhaust system, which means dry type exhaust manifold and dry-type turbocharger, We provide upgrading services for water-cooled exhaust systems, which modify dry type exhaust system into the water-cooled exhaust system, which are quite important and often requested by passenger boat projects.

Advantages of the KTA38-850 Marine Engine include:

  1. Integrated Design: The cylinder block and cylinder head feature an integrated design, minimizing the risk of water and oil leakage and reducing failure rates.
  2. Enhanced Durability: Strengthened cylinder liners and chrome-plated piston rings improve engine durability and prolong its lifespan.
  3. Compliance with Regulations: The engine meets the requirements of China Inland River 1, China Inland River 2, and IMO Tier 2 stage emission regulations. It adopts the BHT3B supercharger optimized by Chongqing CMI for marine engines, enhancing emissions control and engine reliability.
  4. Efficient Fuel Combustion: High injection pressure, overspeed protection, low-pressure fuel supply, and fewer pipelines contribute to full fuel combustion and high-efficiency energy-saving effects.
  5. ESTC Electronic Oil Timing Control Valve: Equipped with an ESTC electronic oil timing control valve, the engine accurately supplements and adjusts timing, improving combustion smoke color at low idle speeds.
  6. Reasonable Exhaust System Design: The exhaust system design by Chongqing CMI incorporates a water-cooled supercharger and water-cooled exhaust pipe, reducing engine surface temperatures and meeting SOLAS safety regulations.
