Tom,
I am familiar with the reasons why diesel engines naturally
produce limited compression braking compared to gas engines as well as
how and why exhaust brakes are used. But I had the understanding that
an exhaust brake was only activated on demand by the driver.
What I was not aware of is the idea that the exhaust brake is
either switched on or switched off and is activated every time you lift your
foot from the throttle pedal. I don't think I would like that
method of operation. Are all brands of aftermarket exhaust brakes
activated in the same manner?
I know that Jacobs, the original "Jake Brake" which has been
used on 18 wheelers for 30 years or more is authorized by Cummins, the engine
manufacturer for sale and installation on Cummins engines including Cummins
powered Dodge Rams by either Cummins shops or Dodge dealers. I checked and
found that a local Dodge dealer can sell it through MOPAR parts and install it
in their service department.
Has anyone out there had any experience with a Jacobs "Jake
Brake"?
Harvey
