What components are included in tacho-gen systems?

• A. A fuel pump and oil cooler
• B. A generator and speed sensor
• C. An ignition coil and battery
• D. A throttle body and air intake

Answer: (B)

Tacho-gen systems are designed to monitor and provide information about the rotational speed of a turbine engine. The correct answer includes a generator and a speed sensor, which are essential components of this type of system. The generator in a tacho-gen system converts mechanical energy from the engine's rotation into electrical energy, allowing for the measurement of speed. This electrical output can then be processed to display the engine's speed on a gauge or feed information to the engine control system for various operational decisions. The speed sensor complements the generator by providing real-time data on the rate of rotation. It detects changes in speed and sends signals that contribute to the engine's performance monitoring and control. This combination ensures that the engine operates efficiently and safely by continuously providing feedback on its performance. Other options listed, such as a fuel pump with an oil cooler, an ignition coil with a battery, or a throttle body with an air intake, do not relate to the function of a tacho-gen system. They are components associated with different systems within an engine: fuel systems, ignition systems, and air management systems, respectively, and do not play a role in measuring engine speed.
