Design

The PBS TS100

engine is equipped with an autonomous oil and fuel system, brushless electric starter generator and a digital ECU. The ECU controls the acceleration and deceleration of the

gas generator A gas generator is a device for generating gas. A gas generator may create gas by a chemical reaction or from a solid or liquid source, when storing a pressurized gas is undesirable or impractical. The term often refers to a device that uses a ...

to maintain a constant output shaft speed. The ECU also provides subsequent automatic cooling of hot components after the engine stops. The

engine can be controlled by an analogue or digital interface. The maximum continuous power mode of 214 hp (160 kW) is available up to .

Variants

Two versions of the PBS TS100 engine are available based on the number of rpm: * PBS TS100 ZA with 5,978 RPM * PBS TS100DA with 2,158 RPM

Applications
