Advantages of KTA19-M470 Marine Propulsion Engine
Proven Reliability in Marine Conditions
The KTA19-M series is widely used as a marine main engine due to its robust mechanical design and long service life. It performs consistently in harsh saltwater environments and heavy-duty cycles.
Fuel Efficiency & Operating Cost Reduction
Compared with older K19 models, the KTA19-M470 offers improved fuel efficiency and optimized combustion, making it a cost-effective solution for operators of 20–30 meter tugboats and cargo vessels.
Compliance with International Standards
This engine is available with:
- CCS certification
- IMO Annex VI compliance
The PT Fuel System & Maintenance Specs
The Pressure-Time (PT) fuel pump system is designed for high injection pressure and overspeed protection. For fleet managers, this means simpler PT fuel system troubleshooting and lower maintenance overhead. At HekoPower, we provide the full KTA19 engine maintenance schedule PDF to our clients, ensuring your crew can manage routine service—from replacing a KTA19 injector to optimizing fuel flow—without needing proprietary electronic tools.
Turbocharging and Cooling Efficiency
Equipped with a Holset HX80 turbocharger, the KTA19-M470 achieves superior air intake efficiency, resulting in a cleaner burn and better response. The engine features a sea water cooled system with a high-efficiency heat exchanger, ensuring stable operating temperatures even in tropical waters. This cooling configuration, combined with 24V electrical starting, allows for a low temperature start at -12℃, making it versatile for global shipping routes.
Typical Applications of Cummins KTA19-M470
The versatility of the 19L marine propulsion engine makes it a "workhorse" across various sectors:
- Tug Boat Propulsion: The KTA19-M470 is ideal for 20-30 meter tugboats requiring steady bollard pull.
- Fishing Trawlers: Provides the continuous power needed for deep-sea dragging.
- Cargo Barges: Optimized for 500-800 ton vessels navigating inland waterways or coastal routes.
- Offshore Supply: Reliable main propulsion for workboats and pilot boats requiring IMO Tier II compliance.
KTA19-M470 vs KTA19-M500 – Key Differences
When comparing the KTA19-M470 with the KTA19-M500:
