[Vwdiesel] Diesel braking - again

[LBaird119 at aol.com]

ok, i've been thinking about this. sorry to bring this
up again, but i just can't get it off my mind. :)


I see it pretty much the same way you do.  However I've noticed that 
the gas DO engine brake better than diesels notieably but nothing 
to really brag about one way or t'other.  The compression should make 
the diesel better but pulling against a vacuum helps the gas.  Appears 
the vacuum is mightier than the pressure.  

>    So why do you think they put those expensive Jake brakes on diesel
trucks? They sure don't put them on gasser trucks.

  Probably because they don't MAKE them for gas engines.  Won't work
without cylinder injection.  You'd suck raw fuel right through the engine.  
Wouldn't set well in the past and CERTAINLY wouldn't set well with 
the EPA!  Fuel could be cut but generally I'd assume and exhaust brake 
would make it comperable to a Jake'd diesel, and legal in many more 
places.  I've never seen an 80K gvw with a gas tho.  I heard they tried a 
few turbine models way back when. Talk about no engine braking!
