Morning cold startup for hybrid motor

[Gray Goose]

Better than an parked warm up is to drive slowly for the first mile. Keep the engine close to idle RPM. This allows the transmission oil to start circulating as well.

For a hybrid, once engine kicks in the vehicle is already moving so not much additional power is needed. The engine RPM shouldn't be much above idle after it kicks in.

In a normal car, you start the motor and let it run to allow the oil and lubicants to flow around the engine before getting under way. At least I do, especially on cold mornings. The hybrid however doesn't start until it is needed. When I first take off it's on battery only and then the motor kicks in.

Is it a problem for the motor to start under load without first circulating the oil and such?

If this is an earlier thread I couldn't find it.

If you put HVAC system to max defrost the engine will start after 30 seconds or so to warm up the coolant you can let it run in your driveway before you take off

Hybrids have been around for a long time. I’m sure it’s fine.

Good Morning, does this mean that you could simply sit there with electric motor on, switch through the gears and everything would be lubricated? The transmission has an oil pump, to feed the stators for cooling. If not, is there a way to start the engine without unhooking from your tow vehicle? yes my hybrid will be a toad behind an RV so my needs are special! Thanks all

In the lariat trim, does the steering wheel and seats warm up when you start it in the winter? Never had anything that fancy so i don't know. I only have the XL

I start mine with the cell phone and 30 seconds later the engine starts but air is off and temp. set for 72 and is toasty when I get in.

If you are doing this to warm up the cabin, I understand. I do the opposite to cool the cabin in mine. If you are doing it "to allow the oil and lubicants to flow around the engine before getting under way" , It is unnecessary.

Great question. I been wondering the same thing, cause if you drive on electric for a ways and then the gas engine starts it seems like the gas engine is running at a higher rpm then normal. But if i start the gas engine right away in the garage by pushing gas pedal to floor before leaving it seems like the gas engine doesnt run near as hi rpms. I would think stating the gas earlier would be easier on the engine.

My 23yr old Miata revs up to a high RPM for the first bit after it's first turned on, I'm sure Mav will be fine...

Start hit throttle engine will fire on hybrid .

In a normal car you don't and It is not recommended to start the motor and let it run to allow the oil and lubicants to flow around the engine before getting under way.

From Consumer reports: "Modern cars have improved in technology to the point where your engine is fully lubricated within 20 to 30 seconds. By the time you get in, start the car, put on your seat belt, and get comfortable, the engine might not be fully warm. But it’s completely lubricated, and you’re okay to drive at this point."

But normal cars the engine isn't under load at startup. The engine circulates the oil, can't imagine cold starts are good at 3500 rpm.

Who's talking about 3500 rpm except you?

Here's a little known tidbit:

The Maverick will hold at 1250 RPM during the warm up stage, so long as you don't mash the pedal to the floor to override this "eco friendly" warm up phase.

Even though the engine is spinning, you are getting your torque for driving from the HV battery and electric motor. For as long as the battery lasts, but for this cold start, the programming allows deeper discharge of the battery than at any other time. Mostly for emissions reduction reasons. But it's also gentle on your engine.

The engine is held at idle until the catalyst reaches "light off" temperature, the minimum temperature to break harmful emissions into less harmful byproducts. By mounting the catalytic converter as close to the engine as possible, this catalytic converter gets to operating temperature faster than a vehicle from previous decades. The engine also runs a little rich during a cold start. Extra fuel heats things up faster getting to lower emissions faster and is one reason why MPG is low for people making short trips on a cold engine. It's counterintuitive but bean counters have found burning MORE fuel on a cold engine, is a net savings of pollution to get to a warm catalytic converter, sooner.

If it's winter, and your battery is well charged, and your cabin heater is off, the engine will still run every few minutes, just to keep the catalytic converter warm enough to break down emissions.

This is Ford's 4th generation of Hybrid.
Not much has changed from the 1st generation. One thing that has: much faster warm up, and mounting the catalytic converter closer to the engine both gets it warmer, faster, and keeps it warmer, longer, if you drop into EV mode in winter.

In the Gen1 Escape Hybrid you couldn't drive EV in winter hardly at all not because the battery was cold, but the Catalytic converter would cool off at a single stoplight.

Auto startup about 15 minutes before I leave every day when it's cold out. Best idea ever,

GPSMAN
Worst idea ever.

Since you have hot air in these in 3 minutes. If not, have yours checked out.


The heater is not electric as far as I know and it gets below zero here and it still wasn't real warm. So actually the BEST idea ever.

I didn't know how it worked or the RPM's as I don't have tach, the 3500 RPM was just an estimation. That being said, my truck the engine doesn't turn on until well underway (40/45mph) and the engine sounds like it's spinning more than 1200 RPM.

 

[GPSMan]

1250 is "idle".

While there are infinite possibilities, 2500 is a very efficient sweet spot, so it spends a lot of time there.

Rarely more than 2500 unless you are accelerating more than average rate. Or climbing more than a gentle hill.
