NATO Supply Class 2920 is a classification for Engine Electrical System Components, Nonaircraft. It falls under NATO Supply Group 29, which is specifically for Engine Accessories.

Engine Electrical System Components, Nonaircraft (NATO Supply Class 2920) refers to a wide range of electrical components that are used in engines for non-aircraft applications. These components are essential for the proper functioning of the engine's electrical system.

Some examples of Engine Electrical System Components, Nonaircraft include:

1. Starters: These are electric motors that are used to start the engine by cranking it until it reaches the required speed for ignition.

2. Alternators: Alternators are responsible for generating electrical power in the engine. They convert mechanical energy into electrical energy to charge the battery and power the electrical systems of the engine.

3. Ignition Systems: These systems are used to ignite the fuel-air mixture in the engine's combustion chamber. They typically consist of spark plugs, ignition coils, and control modules.

4. Voltage Regulators: Voltage regulators are used to maintain a steady voltage output from the alternator to prevent damage to the electrical components of the engine.

5. Sensors: Various sensors are used in the engine's electrical system to monitor parameters such as temperature, pressure, and speed. These sensors provide crucial data for engine control and diagnostics.

6. Wiring Harnesses: Wiring harnesses are bundles of electrical wires that connect various components of the engine's electrical system. They ensure proper electrical connectivity and prevent wire damage.

It is important to note that NATO Supply Class 2920 specifically refers to non-aircraft engine applications. For aircraft engine electrical components, a different supply class would be used.

Overall, NATO Supply Class 2920 plays a vital role in ensuring the efficient and reliable operation of engine electrical systems in non-aircraft applications.
