RowdyRebel Posted April 19, 2009 Share Posted April 19, 2009 Hi everyone,Could you pls explain the difference between E7 & EM7 engine types to me? Also what are the advantages of Engine Brakes and double frames? we have a rough terrain here in Nigeria.Thanks and really appreciates repliesThis is just a shot in the dark guess, but I'd say the Em7 is probably a mechanical engine, where the E7 is electronic. Someone can correct me if I'm wrong.Engine brakes help keep your speed in check coming down a hill without relying upon your foot brake as much.Double frame refers to the frame rail having an insert, so it's stronger than just a single frame.

HK Trucking Posted April 19, 2009 Share Posted April 19, 2009 Actually, the EM7 would be a Maxidyne, and the E7 is Econodyne.Both could be either mechanical or electronic, depending on year of Mfg, or customer spec.

Lmackattack Posted April 19, 2009 Share Posted April 19, 2009 double frames add strength to the truck. if its an off road truck the double frames often reduce the stress and twisting thus extending life of the frame. the down side is that rust can get inbetween the rails and spread them to the point where crossmember bolts snap.engine brakes help slow the truck and help maintain a safe speed on a downgrade. it allows you to use less of your service brake on a hill and extends service brake life, ruduces brake fade etc...
