OM616 basic questions

Verfasst am: 19.09.2006 07:26:11 Titel: OM616 basic questions

Dear all,

Being a newbie, I am unclear about

1) Why is it that IDI engines have more compression ratios than DI engines? If IDIs sacrifice mileage/torque for smoothness and accleration, I would think that the compresson ratio needs to be the same if not lesser than DI

Can some one post a pic of the cylinder head? Is that the place where the pre-comb chamber is located?

2) Is the design of the IDI pistons different in any way as compared to the DI pistons?

3) Why do TC engines have oil spray and NA engines do not have them? Why is it that the combustion temps are more on a TC engine? If one has an Intercooler , by how much does it reduce the need for oil spray. I am asking this question because I have an acquaintance who wants to get a normal OM616 and wants to TC it.

And generally any pictures you can post of the mechanical aspects will be much appreciated.
