Marine & Offshore

Marine main engines, high-power auxiliary engines, offshore platform support vessels, and coastal engineering ships powered by the latest C15 series engines.

Power Generation

High-capacity stationary generator sets (920 - 1120 kW) for industrial parks, data centers, hospitals, and critical infrastructure emergency backup power systems.

Performance Feature

Detailed Benefits & Performance Data

Fuel Flow & Atomization

Ultimate high-flow nozzle design delivers 59% more fuel flow than standard injectors; ultra-fine fuel atomization (spray variance under 0.18%) ensures uniform air-fuel mixing and complete combustion. This design reduces fuel consumption by 24-27% compared to standard components.

Electronic Control Precision

Equipped with a next-generation high-response solenoid valve, achieving microsecond-level injection timing accuracy. Integrated with the engine's onboard diagnostic system, it ensures precise fuel metering, eliminates fuel dripping and leakage, and maintains stable idling and seamless power delivery across all speed ranges and load conditions.

Durability & Reliability

Constructed with advanced high-temperature and corrosion-resistant materials to withstand the harshest operating environments. Factory-leak tested and calibrated, ensuring consistent and reliable performance for over 25,000 hours of continuous operation.

Emission Compliance

Integrated with the engine's advanced exhaust aftertreatment system, effectively reducing particulate matter (PM) and nitrogen oxide (NOx) emissions to near zero levels, fully complying with global emissions standards and supporting green and sustainable operations.

Assurance & Service Item

Detailed Description
