NATO Supply Class 6620 is a classification within NATO Supply Group 66, which is dedicated to Instruments and Laboratory Equipment. Specifically, Class 6620 focuses on Engine Instruments.

Engine Instruments are devices used to monitor and measure various parameters and performance indicators of engines. These instruments play a crucial role in ensuring the efficient and safe operation of engines in various applications, including automotive, aerospace, marine, and industrial sectors.

Some examples of Engine Instruments that fall under NATO Supply Class 6620 include:

1. Tachometers: These instruments measure the rotational speed (RPM) of an engine's crankshaft. They provide valuable information about the engine's performance and help in monitoring and controlling its speed.

2. Pressure Gauges: These instruments measure the pressure of fluids, such as oil, fuel, or coolant, within an engine. They help in monitoring the engine's oil pressure, fuel pressure, and coolant pressure, ensuring proper lubrication and cooling.

3. Temperature Gauges: These instruments measure the temperature of engine components, such as coolant temperature, oil temperature, or exhaust gas temperature. They help in monitoring the engine's operating temperature and prevent overheating or other temperature-related issues.

4. Fuel Flow Meters: These instruments measure the rate of fuel consumption in an engine. They provide valuable information about fuel efficiency and help in optimizing fuel consumption.

5. Oil Pressure Switches: These instruments monitor the oil pressure within an engine and provide an electrical signal if the pressure falls below a certain threshold. This helps in detecting oil pressure issues and preventing engine damage.

6. Engine Hour Meters: These instruments measure the total running time of an engine. They are used for maintenance purposes, as they help in scheduling regular maintenance and tracking the engine's usage.

These are just a few examples of Engine Instruments covered under NATO Supply Class 6620. The class encompasses a wide range of instruments used for monitoring and controlling various aspects of engine performance.
