Design and development

The engine marked a departure from earlier Argus engines in that it had new construction techniques which gave the engine greater operating speeds and power. The engine featured smaller 105 mm x 115 mm cylinders with deep finned steel cooling slots, aluminum heads, geared supercharger, a steel alloy crankshaft and a magnesium alloy crankcase. The engine weighed approximately 315 kg and produced 465 PS (459 hp, 342 kW) at 3,100 rpm. Approximately 28,700 engines were produced.[2]

A distinctive feature is the finned spinner ahead of the propeller. This is driven by the airflow as a windmill, and used to power the actuator of the variable-pitch propeller.

The more powerful and refined Argus As 411 was developed from it.
