Car Forum / Mercedes-Benz Cars / May 2007w124 230E compression?
Please, give me a compression information for mercedes w124 230E ( 132 ks) 1990. year... My compresion is 12 at 1,2,3 and 4 cilider...is it ok? Compression on new car ??? Thanks... Sorry on my bad english... 12 BAR x 14.7 is 176 psi and all cylinders are equal so the motor should run well. It's fine.  Signature© 2007 T.G.Lambach.

Depends on motor temperature, external air pressure, oil pressure, opening of the throttle and starter rpm. The geometric compression is around 10 plus adiabatic compression heating but cylinder filling is not complete, so 11 to 13 bar is always a good value. All cylinders should have the same value at least 9. Compression problems typically start at one or two neigbouring cylinders. SignatureRoland Franzius |
