if i'm not mistaken, the etorque system only activates whenever the vehicle is coming back on after auto start stop. not every single time you accelerate from a dead stop.
The system does add torque for the first half turn of the wheels according to videos that were regularly circulated when 5th gens first came out with etorque.
Perhaps you mis-spoke. Etorque provides no torque on engine start but does add torque on take-off.
Seems a mix of I mis-spoke and mis-understood as to how the system works. The video is a clearer explanation than what I wrote, and it does provide more torque to the road in the early rev pulling away from a stop sign. The video shows it does so for longer than I understood it to provide the electric boost.
this is what i was trying to explain, when turning back on from a auto start stop cycle.
It’s not just after an auto start stop cycle. For instance, if you disable stop/start the etorque motor/generator adds torque when taking off from a stop. Disabling stop/start does not disable the other features of etorque.
Agree. For instance if the AC system can not keep up so auto-start (stop/start) is disabled, the system does still provide some additional torque off the line. Almost never happens for me unless I set the system to max cooling.
interesting
If it's not providing torque on engine start... how is it starting the engine? And since the truck is still in gear, with the engine spinning up, yes, it is providing torque. The videos and articles regurgitate marketing information which is largely lacking in how the system actually works.
That video does not tell the whole story. If you use an OBD tool with an app, you can view live input/output of the 48V system. When I had a 2021 with eTorque before getting my EcoD, I drove around for a bit watching what the system did. When taking your foot off the accelerator and not touching the brakes, the system was idle i.e. there is no regenerative braking taking place until you apply at least a miniscule amount of braking pressure - this makes sense because coasting is the most efficient thing you can do once you're already moving. During regular cruising, with adequate charge, the system provided torque to aid the engine for short periods of time - it does this so the battery can drain to have spare capacity for regen during braking, and and also saves some fuel. eTorque plays a role in upshifts and downshifts - it provides smoother shifts through its direct control of engine speed and in turn saves fuel & transmission wear through rev matching by increasing engine speed during downshifts, and recaptures energy by slowing the engine during upshifts.
That was just one of many videos that are out there. There are also Mopar videos out there which say basically the same thing but I wasn't able to find them in my quick search. You're free to search on your own if you don't like that one.
I get what you're saying. I misunderstood what you meant in your previous post. Apologies to you sir.
Admittedly that's not the best video out there. As I said above it's what I came up with in a quick internet search. There are better videos out there that I've seen but those didn't come up with my search. Maybe I'll spend some time and find the one that was put out in 2018/19 which did a great job explaining the system, and mentioned some of the points you made above.
