GENERAL SPECIFICATIONS

SDEC 88kW Diesel Engine

Flexible Performance and Better Airflow

The SDEC 4HT4.3-G23 engine uses a vertical inline 4-stroke design engineered for operational flexibility across varying load demands. Featuring four valves per cylinder, it maximises airflow and ensures excellent fuel atomisation. This allows the engine to deliver smooth, reliable torque whenever your facility needs backup power.

Strong Build and Lower Maintenance Overhead

Constructed with an integrated cylinder head and a high strength cast iron block, this engine uses top tier components to ensure reliable operation. The dry-liner layout makes servicing straightforward, while the simplified internal design drastically reduces the total number of parts. Fewer components mean fewer potential breaks, lower long term running costs and maximum reliability in tough African environments.

Versatility Meets Advanced Engineering

Constructed with an integrated cylinder head and a high strength cast-iron block, this 4.3L powertrain is specifically engineered for multi speed operational flexibility. The advanced 4-valve layout guarantees precise fuel atomisation and smooth torque delivery, making it a highly adaptable choice for local generator builders supplying commercial complexes and agricultural projects. By routing internal lubrication lines directly through the block, significantly reducing leak risks and maximising field uptime under demanding conditions.

Core Technical Highlights

  • Optimised Thermal Dissipation: The overhead 4-valve architecture enhances airflow and combustion efficiency, extending the structural longevity of the engine under rigorous load cycles.

  • Automotive-Grade Precision: Manufactured under the strict quality control matrix of SAIC Motor and verified by world class German production standards for balanced, dependable performance.

  • Streamlined Framework: The design relies on integrated components to lower the overall part count, resulting in simpler field maintenance and reduced spare parts overhead.

  • Reliable Ignition: Starts instantly without an intake pre-heater down to -10°C, and handles extreme drops down to -30°C when paired with an auxiliary heating device.

  • Emissions Compliance: Fully matches the Off-Road Stage II framework, ensuring a cleaner fuel burn and highly efficient consumption profiles.
