GENERAL SPECIFICATIONS

SDEC 400kW Diesel Engine

Precise Fuel Delivery

The SDEC 6ETAA12.8-G32 engine features a world class Bosch fuel system paired with an air-to-air intercooled turbocharger. This setup ensures highly efficient fuel combustion. When your operation experiences a sudden jump in power demand, the engine stabilises its speed immediately, preventing voltage drops and keeping sensitive equipment running safely.

Built for Demanding Industrial Conditions

Designed to handle severe grid instability and high temperatures, this engine uses a durable dry-liner block configuration. A large 36-litre oil sump provides superior internal cooling and lubrication during extended power cuts, ensuring long term reliability for major commercial and industrial operations without adding unnecessary maintenance hassle.

Robust Build with 4-Valve Efficiency

Built with a high strength cast iron block and an integrated cylinder head, this engine uses premium international components to handle demanding large scale workloads. Its 4-valve design improves fuel atomisation and delivers steady torque, making it a reliable choice for local generator builders and engineers powering commercial, agricultural, and industrial infrastructure.

Simplified Layout and Maintenance

The engine is designed with fewer individual parts, reducing mechanical complexity compared to standard large engines. This straightforward layout keeps field servicing simple, lowers your long term spare parts costs and ensures maximum uptime under harsh African conditions.

Key Technical Features

  • Efficient 4-Valve Layout: The cylinder block and integrated head 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 costs.

  • Reliable 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 fuel consumption.
