What type of engine is in my car (exactly)?

2008 Honda Accord Ex-L 2.4L Inline 4 cylinder DOHC IV-tec

I believe it's a K series

But whenever I google the exact specs I keep getting directed to "Buy this or buy that" type websites…

So I'm a little aggravated with search engines, can anybody clarify what exact type of engine I have in this car…

Is it a K series B, C, X, A, cause I have absolutely no clue and I've been combing through the internet for about a month now…

K series is a Rover/MG engine that Honda have used and I believe was never made over 2.0
