whats the difference between a 4 stroke diesel 2 stroke diesel i know the difference between a 2 and 4 stroke

Answer 1

They are basicly the same as a gas engine! A two stroke fires every round, a four stroke on every other round(Crankshaft). Four stroke's tend to have more low end power, and torque than a two stroke. Which with a diesel engines lower RPM spread is a huge advantage. Detroit Diesel made quite a few popular 2 stoke diesel engines in the 60's, 70's, and mid 80's. The 892TT was available in buses as a computer controlled application until the Series 60 came out in the early 90's. The Detroits were easy, and cheap to rebuild. The only problems I ever had with them were the "routerbit" injector tools, and getting the fuel rack to stay in adjustment. Otherwise good dependable engine. They did have a tendancy to slobber oil though. Hope this helps!

Answer 2

I personaly would have bet there wasn't a four stroke. Good thing I check before putting money on it. Try:
