SDEC SC9D240.21CA2 Marine Engine

SDEC SC9D240.21CA2 marine main engine is a 6-cylinder design, 6-cylinder engines are usually suitable for a large number of boats or applications that require higher torque and power output.

SC9D240.21CA2 has a displacement of 8.8 L, larger displacement means better acceleration performance and handling stability, especially suitable for heavy-duty or high-load working environments.

The Engine has a rated power output of 172 kW, enough to drive large vehicles or provide high performance, which is important for applications that require quick acceleration or long distance runs.

We provide all customers with full life cycle services from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from troubleshooting to maintenance technical support.

Advantages of SC9D240.21CA2 Marine Engine

  • Easy maintenance and high attendance. Integrated design of engine parts, fewer sources of failure, nationwide service network, cheap parts and sufficient supply.

  • Powerful, efficient and fuel-efficient. Four-valve structure, turbocharger matched according to the working conditions of the ship to achieve higher air intake efficiency, Japan Denso electronic control system is adopted, the maximum injection pressure is 2000 bar, the atomization is uniform, and the combustion is sufficient. The practical application has large power margin, excellent emission, low fuel consumption and low operating cost.

  • Compact structure, excellent NVH. Modular design of the engine, small size, easy to arrange the cabin, light weight, low engine noise and vibration.

  • Rich configuration and high comfort. According to the different operating conditions of the marine engine, the configuration of the engine is optimized. Water-cooled supercharger and water-cooled exhaust pipe, flywheel interface, etc., large-capacity oil pan, etc. are optional. The ambient temperature of the engine room is low and the comfort is high.

  • High reliability and good consistency. Machining and assembly lines are controlled by MES production system and guaranteed by SPS system. The selected diesel engine parts are of high quality, high reliability and good consistency.
