to be connected with

[Ksenia]

The competence of XXX (company's name) is the internal combustion engines and everything that is connected with them.

It's grammatically correct to use "everything that is connected with them" but I am wondering if there is any other ways to convey the meaning of this phrase?

Thank you.

I'm assuming that by 'connected with them' you are referring to the subject of combustion engines and not the mechanical aspect.

If that is the case, how about, '…and everything appertaining to them'?

The meaning isn't 100% clear to me, so there could well be other ways of saying it.

Everything that is connected with the internal combustion engines... For example: repair kits, spare parts and so on...

How about Anything to do with internal combustion engines? However, these are tools/accessories to me.
