Why is the engine in the Ford Fiesta making a strange noise?

The engine in my Ford Fiesta has started making a strange noise, especially when I accelerate. What could be the cause of this and how can I fix it?

This could be due to a problem with the engine's pistons or valves. I would recommend taking your car to a mechanic for a closer inspection and repairs if necessary.

The noise may be coming from a loose belt or fan. Check under the hood and tighten any loose components, or take it to a mechanic to have it checked.
