Start-Stop

Have anything to back that up that up I can read? Always open to learning... but if you have ever had anything with a manual choke you know it's not needed when the engine is warm. I can't see a reason you would need to richen it up with FI either.

 

Maybe when the engine turns off, the A/C also gets turn off. Maybe they can have all the windows roll down the same time? Just kidding. Lol

I have been driving old cars for life. This 2019 Tacoma of mines really open my eyes to how advance we became.
You could say I being living in a cave? When you live on a farm, things are still done by hand. We got modern tools like the “ shovel “?

I use maybe only 2% of my smart phone features. “Hello” , “Goodbye”. Not sure why text is use more now then the speaking?

there ya go. how a proper BSG stop/start system works.

none of the proper systems stop at stop signs. or in your example "1 second" at a quick light.

if it didn't help MPG they wouldn't be doing this.

 

Just hook up a scan tool that can read fuel trims and do a few start cycles, can't compare a 3.5 6 cylinder engine to a 1 cylinder Briggs and Stratton with a choke. FYI those engines always run very rich, so rich it would throw code if you ran your 3.5 at that fuel to air ratio, and even richer with the choke. I own a 4 cylinder boat motor, still not the same, but much closer to the 3.5 in scale and operation, and you always need some amount of choke to get a quick start. If you let it crank for 3 to 4 seconds it will start without it, but a start like that would be useless for a start stop system. The answer is compression isn't very high when the engine is at starting RPMs, compression that low means unreliable ignition and need more fuel to make sure a light-off happens. As far as something you can read I'm sure you can find many things on google to disprove and prove what I'm saying, I'm basing it of my own knowledge of how an engine works based my schooling, and my own experience as an A&P mechanic.

 

I agree, but people look at the small picture….

 

I was actually using my snowmobile as an example. If the motor was warm it fired right up with no choke but the cooler it was the more choke you needed or the longer it took to start. Auto/start stop knows what cylinder(s) are about to fire and injects fuel into them early for a quick fire; which is pretty much the same as you using the choke on the boat. Even if the system runs slightly rich for a split second it'll still save fuel.

To be clear I don't like the system. The tradeoffs aren't worth it to me.

 

What a lovely commercial for the ram 1500. Everything in this video is just RAM jerking itself off, what little data is in this video has no sources. There is no provision for lubrication so bearing wear is still going to be an issue. I think 90 seconds for a stop light is a lot, I think 20 to 30 is much better at least around were I drive. The whole system is just a worse version of a hybrid, they should have just made a full hybrid truck and been done with it. To be clear I think start stop hybrids are good, the electric motor in them spins the engine much faster than a starter, this builds oil pressure before the engine fires saving some bearing wear. Also the faster rpms means less fuel is needed in the start sequence. This is just a half assed attempt at strapping a hybrid system to a motor as an afterthought. Also the idea that companies wouldn't do this if it didn't save mpgs is wrong, notice how the rep in the video didn't even give a solid mpg savings number? Marketing departments control most big companies, and if they think people with buy something they will have it put in a vehicle. They can say "look its a not hybrid, hybrid truck" this lets them cater to the hybrid crowd and the not hybrid crowd at the same time, quite clever from a marketing standpoint, but it has nothing to do with MPGs.

 

bro you don't have shit for sources either other than being an airplane mechanic.

it is about average mpg as seemingly every year the automakers have to lower their average mpg across their entire fleet, ex:

it also doesn't only turn on after 90 seconds. that was just an example. you sound like my grandpa who was scared of fuel injection because he used to be able to tune his racecars by ear with a screwdriver.

and it doesnt cater to the people you think it does because every 2 digit IQ moron turns it off as soon as they get in the truck.

 

What your grandpa believes has little to do with me, this video is just a Ram commercial. If understanding the physics of an internal combustion engine, every detail of how it works and why it works isn't enough for you then I don't know what to say. If your doctor told you that you had high cholesterol would you just say "I don't believe you the internet says I don't, all the medical school you went to is worthless"? some people man....

 

Those commercials works and is very convincing for reasons to buy the Ram 1500 4x4!

Looking at the size of the Ram 1500 4x4 vs the Tacoma in the mpg? Not too much difference? The Ram 1500 gives more space , more comfort, safer in a collision, head room, etc.

I used to own a 1986 Dodge Ram 4x4 with a 8’ bed. It took me to every off road fishing spots on the Big Island of Hawaii. There was no road where I could not go. I kinda miss the Ram , but I was getting under 10 mpg. Got too old.

My 2019 Tacoma TRD 4x4 after the lift , tires ,armor, camper top, I am getting less then 13 mpg.

The Dodge Ram E-Torque is beginning to look good! Google web shows the 3.6 liter Pentastar V-6 with e-torque gets 20/25/23 mpg.
The 3.0 EcoDiesel V-6 22/32/26 mpg .

Will all those systems work with a lift and bigger tires? Sure I know the mileage will come down.

 

When I lived in Japan back in 2013, almost every car I drove had start/stop, even cheapo K-Cars. It honestly freaked me out at first, but got used to it after a month or so. The delay at a red light wasn't bad either.

Some have mentioned that Start/Stop would wear out the poor starter, but from what I have seen, the starter on Start/Stop vehicles are a LOT beefier.

I personally would just be worried about the battery, which are your typical 12v lead acid.

 

Japan had start/stop systems in 2013? Is America that far behind?
Off course we loved our emissions, helps with climate changes. Kidding here!

it’s going to be a new way to learn and drive. Dodge Ram e-torque may have solve the early problems, with the start/stop?

Remember those days of shifting in neutral, when going down hills to save gas?

The only other time , we use push start is when the battery is dead? ( standards) . Every one pushes the car.
I also learn how to jump start a dead battery in a automatic, need another car to tow you at higher speeds. Without a jumper cable.

 

I have a 22 manual tranny Tacoma, no stop/start, no push button start.

 

Toyota mentions the new High Lander V6AWD & Rava LE AWD will have the Start/Stop, maybe the Tundra hybrid?

AUTO PARK - Toyota is adding lots of safety features to there line up of vehicles.
Auto-parks : works when you open the car door , it will automatically put your vehicles in the park mode!

 

The best safety feature is the one between your ears, I've never gotten out of my truck when it wasn't in park when using it. You should try it sometimes, works really well.

 

Yeah, a good majority of the eco and K-cars I drove or rode in had them. My gf's 3cyl K-car had it and it was barely noticeable at a red light. I think the starter also helps move the vehicle forward, and feels similar to how clutch start cancel works on the MT Tacomas.

Pretty sure I have seen a BMW with start/stop before 2013.

Speaking about things Japan had before the rest of the world, was being able to pay for things with your phone. Osaifu-Keitai service similar to GPay/ApplePay, but back in 2008.

 

The deaths from people getting out of there car, forgetting to put in park and handbrakes on ,is very numerous.
Someone mention a well known movie actor park his Jeep and roll backwards killing him.

The videos of vehicles rolling backwards because of this is hilarious. And some deadly.

You mention the safety feature is between the ears, but the “nut” behind the steering is a major cause of accidents.

What did one “eye” say to the other “eye?” “Between you and me something smells”

 

Forgetfulness is a common human trait. More common then you think?

To Remember everyone names is a blessing we all wish we could have. Wife’s birthday? Wedding Anniversary? Children birthdays. too.

Did I forget something? OH, The thing between my ears? Thanks.

 

If you don't have the brain capacity to put 4000 pounds of steel in park, leave it in drive and run someone's kid over because you walked way from your still moving car, you just shouldn't own a car, it doesn't matter what safety features it has, you will seriously injure someone with it. you really should consider engaging your brain when operating a car, your going to hurt someone with it.

 

38,224 people die in car accidents in 2020. Averaging over 100 people a day die. Not counting 2021 .
Why is car insurance required? Because accidents happen. Auto- Park will save lives, maybe yours or your children.

Must be nice to have a perfect accident driving record, I cannot claim that. Not perfect here.

Safety features on all vehicles will grow and grow to protect us. . I am glad for the few safety features on my Tacoma. Wish there was more.

Drive safe everyone. Yea! I know we gotta watch for the other guys.

When I hear on the news about another baby die in a “hot car” it is a sad feeling , and preventable. There are now cars made to alert drivers of kids in the back sits.

Forgetfulness , happens! We don’t mean too…..
