Will a hydrogen generator hurt my 69 volkswagen bug?

I have a 1969 volkswagen and I want to put a hydrogen generator in it but I am concerned that the engine will have trouble taking the added pressure from the hydrogen. I want to know before I put it in my car and destroy my engine!

I don't know about added pressure, but the hydrogen will cause it to burn hotter, which isn't good for an air cooled engine, where heat is a critical factor for reliable operation and longevity.

Thank you for your insight!

Would it be safe to drive with the hydrogen generator if I was only driving for at most 30 minutes? in other words, would the car stay at a safe temperature for that long?

I think hydrogen generator is not good for air cooled engines.
