SDEC was founded in 1947 and is a diesel engine manufacturer. They are ISO9001, QS9000 and TS16949 certified, which is testament to their quality and reliability.
SDEC 105kW Diesel Engine
Turbocharged for Immediate Power
The 4HTAA4.3-G21 features an air-to-air aftercooler paired with a precision turbocharger and an electronic governor. By cooling the intake air before it enters the cylinders, the engine improves combustion efficiency and torque. This allows the engine to respond to sudden load steps, maintaining stable frequency control when heavy machinery or equipment is activated.
Integrated Lubrication
Engineered to operate reliably within harsh Sub-Saharan conditions, this engine integrates its lubrication directly inside the cast iron block. This layout removes external oil hoses that can degrade or leak under high running temperatures. Accompanied by a high capacity water cooled radiator and a dry-liner cylinder configuration, it ensures stable heat management and straightforward field servicing.
Direct Torque Delivery
Cast from high strength iron with an integrated cylinder head, this 4.3L engine is built to withstand intensive use. The advanced 4-valve layout ensures precise fuel atomisation and steady torque delivery, making it a highly reliable powertrain for local generator assemblers and engineers building commercial and agricultural systems. By integrating internal components and lowering the overall part count, the design simplifies field servicing and minimises failure points in demanding environments.
Primary Technical Specifications
Thermal Efficiency: The integrated cylinder head and heavy duty block use the best international components to maximise heat dissipation and structural longevity.
Automotive Grade Assembly: Produced under the strict quality control of SAIC Motor and verified by world class German production standards for exceptional balance and mechanical consistency.
Streamlined Engineering: Utilises a design that reduces the total part count compared to conventional engines, making field maintenance straightforward and cutting spare parts overheads.
Sub Zero Starting: Engineered to fire up instantly without an intake pre-heater in temperatures down to -10°C, and handles extreme cold down to -30°C when paired with an auxiliary heating device.
Emissions Profile: Meets global Off-Road Stage II emission standards, ensuring clean fuel combustion and highly efficient consumption.
