My understanding: Engine brake uses engine friction to damp the vehicle momentum. If one wishes to apply engine brake to assist manual gearshift,(activate engine brake, rpm dies, shift to lower gear), will this result in engine stall?
With modern day trucks,I understand idle governor takes care if rpm falls.
However, in below sequence
1)activate engine brake-->Vehicle drives engine-->rpm reduces slowly
2)clutch pedal pressed-->nothing drives engine
3)gear shift done
4)clutch pedal released.Here my guess is,
based on the various factors such as
a)duration of clutch press,
b)previous gear and current gear,
c)based on vehicle momentum,
d)due to sudden loading,
engine might stall and this may not be recovered with governor. So,
a)Is there a possibility of engine stall in above scenario?
b)Is it not safe to have engine brake active during gear shift?
