Applicable Vessel Types: inland river shipping and oceanic fishing boat, and other marine engineering equipment
Product Features
High-Efficiency Power Output
-Turbocharged & Inter-cooled technology (elevated power density and torque).
-Broad operational adaptability with surplus power reserve for diverse workloads.
Fuel Economy Optimization
-4-valve/cylinder design (expanded airflow area, central-mounted fuel injectors).
-Enhanced combustion uniformity (low soot emissions, flat fuel consumption curve).
Simplified Maintenance
-Modular architecture with wet cylinder liners and individual cylinder heads.
-Side-access panels for streamlined servicing.
Compact Structural Design
-Arc-reinforced alloy cast iron body (high strength-to-weight ratio).
-Minimal cylinder center distance for reduced overall dimensions.
Reliability & Safety
-High-strength alloy cast iron body+ forged steel crankshaft.
-Dual-protection gasket system and freshwater-cooled intercooler.
-Water-cooled exhaust manifold (reduced cabin heat exposure).
