* 16V: This stands for "16 valves", meaning the engine has 16 valves that control airflow into and out of the cylinders. Both petrol and diesel engines can have 16 valves.
* DOHC: This means "Double Overhead Camshaft", referring to the engine having two camshafts located above the valves. Again, this is a feature found in both petrol and diesel engines.
To know whether an engine is petrol or diesel, you need more information, such as:
* Fuel Type: The most obvious indicator. Look for terms like "petrol", "gasoline", or "diesel".
* Engine Code: Many manufacturers use specific codes to identify engine types.
* Model Information: If you know the car model, you can usually find out the engine type.
Let me know if you have more details about the specific engine you're interested in, and I can try to help further.
