On one of my buddies 03 Dodge Ram 2500 Cummings Diesl, it says on a decal 24 valve Cummings Diesl. And what I dont get is Diesl engines dont have valves. ? Help me please

 

It might be a 02

 

Diesel engines do have valves.

 

Yes diesel engines have valves. Even the "Detriot" version which is like a cross between a 2 stroke and a 4 stroke.

 

ok my dad is a engine mechanic and he says they dont. He's been one for 20yrs. Iam not arguing iam just wondering why he says they dont

 

Your dad probably works on 2 stroke diesels. They dont have valves.

 

Not to be rude but if your dad has been a mechanic for 20 years he should know better. All the cummins engines have valves. The cummins is a traditional valve in head design. Go to the cummins web site thay have lots of pictures.

 

The 2-stroke detroit diesel has a cam operated exhaust valve that operates like a normal 4-stroke. That would be why ohhell said that they are kind of a cross between the two of them.

 

to tell you the truth he doesnt work on diesl engines only gas as far as I know. He has never torn apart a cummins or detriot motor. If he has worked on diesl then it was a smaller engine.Like a Polaris Diesl atv. he's not a heavy equipment mechanice. Anyway thanx for helping me understand. I never knew their was a 4 stroke and 2 stroke diesl. Thanx again Tbguy20

 

I think your dad is yanking your chain.
