Product Features

Safe and reliable: high-strength engine body, crankshaft, connecting rod, large-flow cooling-and-filtration lubrication system and efficient cooling system, less tube and split head design to ensure the reliability and maintenance of engine parts.

Powerful: Optimized turbocharger, high-pressure fuel pump and fuel injector, with wide power coverage, larger torque reserve and high torque at low speed better for various working conditions.

Excellent fuel economy: Four-valve, pulse turbocharging, large air intake and full combustion lead to minimum fuel consumption rate of 195g/kW-h.

Low vibration and noise: Enhanced key components and high-stiffness spring damper bring low engine vibration and noise. High applicability: The turbocharger can be arranged at the free end or the flywheel end to meet different ship requirements.
