We offer industry leading 24 month / 1,000 hour warranties on our engines and diesel generators.

The SDEC 495kW Diesel Engine (6ETAA12.8-G310) is a high-capacity 12.8L inline 6-cylinder engine built for large industrial and commercial operations. It is designed to run 500kVA to 550kVA generators, combining a premium Bosch fuel system with advanced turbocharging to handle massive electrical loads smoothly.

  • Power Output: Delivers 495kW maximum standby power at 1500 RPM (50Hz), maintaining steady speed through heavy electrical surges.
  • Efficient Layout: Uses an air-to-air cooling system and a precision fuel setup for fast recovery when heavy equipment powers up all at once.
  • Durable Design: Features a 16:1 compression ratio optimised for high turbocharger pressures, paired with a large 36-litre oil capacity for extended running.
  • Reliable Support: Backed by The Generator King’s comprehensive technical expertise, fast cross-border shipping across Africa, and direct access to genuine parts.

We offer delivery across Sub-Saharan Africa at the best prices.

GENERAL SPECIFICATIONS

SDEC 495kW Diesel Engine

High Capacity Power and Rapid Load Recovery

The SDEC 6ETAA12.8-G310 engine uses a large 12.8L displacement and a turbocharged, inline 6-cylinder layout to carry the full load of substantial facilities. It features an air-to-air charge cooling system that lowers intake temperatures to improve efficiency. When heavy machinery or large commercial systems switch on simultaneously, the engine recovers its power immediately, preventing sudden voltage drops and keeping your operations steady.

Engineered for Heavy Commercial Demands

Built to withstand severe grid instability, this engine features a dry-liner cylinder design and a 16:1 compression ratio built for high turbocharger pressures. A large 36-litre dual-level oil sump ensures the engine stays properly lubricated during long blackouts. It delivers absolute reliability for large manufacturing plants, extensive cold storage facilities, and regional shopping centres without unnecessary mechanical complexity.

High Capacity Output and 4-Valve Efficiency

Built with a high strength cast iron block and an integrated cylinder head, this engine easily handles demanding large scale workloads. It features an advanced 4-valve layout that improves fuel atomisation and delivers steady torque. This makes it a reliable choice for local generator builders and engineers who need dependable power for substantial commercial, agricultural, and industrial setups.

Simplified Layout for Lower Maintenance

The engine is designed with fewer individual components, reducing mechanical complexity compared to standard large engines. This simplified layout means fewer parts to manage, which keeps field maintenance simple, lowers your long term spare parts costs  and ensures maximum uptime in harsh African conditions.

Key Technical Features

  • Efficient 4-Valve Design: The robust cylinder block and integrated head use premium international components to improve thermal efficiency and extend the engine's service life.

  • Precision Manufacturing: Produced under strict SAIC Motor quality controls and verified by world class German automotive production standards for excellent consistency and performance.

  • Fewer Moving Parts: Uses integrated components to cut down the total part count, making routine servicing simpler and reducing operational overheads.

  • All-Weather Starting: Starts up instantly without a pre-heater in temperatures down to -10°C, and handles extreme cold down to -30°C when paired with an auxiliary heating device.

  • Clean and Efficient: Meets Off-Road Stage II emission standards, ensuring a cleaner fuel burn and highly efficient consumption profiles.
