K-Series Details

Sdec K-Series marine engine — OBKA Group

K Series Marine Diesel Engine

  • 1. Manufactured to high standards: Developed strictly according to SAIC's GPDP standard process. With an integrated engine design, the marine engine features a high-strength body and cylinder head, forged steel crankshaft, and key components supplied by world-renowned brands. Average overhaul interval exceeds 20,000 hours.
  • 2. Strong power with high fuel efficiency: Designed with four valves, twin turbochargers, full-efficiency air intake, and dual electronic control units. Available in two types: electronically controlled high-pressure common-rail engines and electronically controlled pump-type low-power engines. Wide power and torque range makes it suitable for medium and heavy-duty applications. Minimum fuel consumption reaches 190 g/kW·h, achieving more than 10% fuel savings compared to similar products.
  • 3. High adaptability and flexible configuration: Users can select different models according to operating conditions. For example, the 33W marine engine suits high-speed conditions, while the 38W suits medium to low-speed conditions. Optional configurations include different starting methods, output interfaces, seawater pumps with different flow rates, anti-corrosion cooling systems, and pre-lubrication oil pumps.
  • 4. Comfort & eco-friendly NVH performance: Compact structure with attractive design. NVH-optimized design effectively reduces vibration and noise, improving crew and passenger comfort.
  • 5. Convenient long-interval maintenance: Modular design ensures fewer failures. Single-cylinder and single-head design makes operation and maintenance easier.
