According to VW "the TSI offers a particularly innovative thermal management system with map cooling module"

 

Has anyone of the 1.5 tsi engine owners noticed  improved coolant & oil warm up times so far? 

 

i posted in separate thread 'techy stuff' pdf that mentioned liquid cooling system, when i searched i found articles like this below

Thank you

 

Thanks for posting, very interesting 

I've certainly noticed that the water temperature gauge is up to normal within about half a mile of starting, fastest I've ever seen.

Yep, this is very fast,  definitely. Btw, what about the oil temperature, i.e. can you use the turbo faster too? 

Oil seems to take a bit longer - not sure about turbo usage, I've always been a bit cautious for the first few miles in any new car in any case!

Useful if you have a short commute then

Presumably that's from a stone-cold engine?  Such a swift warm-up must be good for the engine and for efficiency as the ecu can soon switch to a normal lean mixture rather than an enriched mixture for a cold engine. 

 

I would expect the oil to take a little longer than the coolant to get up to temp.  The coolant temperature will be particularly dependent on the heat gerenated from the top of the engine (ie where the bangs are taking place) whilst the oil will particularly depend on the heat built up in the bottom end.  Having said that I expect, as a modern design, the motor will have an oil/water intercooler which will assist getting the oil warm more quickly (and allow the oil to shed heat more easily should it get hot if it is being stressed due to high revs/loadings/high ambient temps).

 

Another benefit in winter time must be a lovely warm cabin heater output in no time!

Yes, that's from a cold start.

it is disappointing that Skoda still use lead acid standard batteries for 2018 and onwards.

 

i red that Mercedes already switching to lithium ion 50V DC batteries, lighter and higher capacity meaning it can withstand all car's electronics better and longer, less weight, i believe BMW also on to this now

Not sure I'd want a big lithium battery in my engine compartment, bad enough when a Samsung phone self-ignites and that's only a small one ;0)

Also, with the price point the Karoq is marketed for, with it's pretty generous standard level of equipment, I don't think it's so unreasonable not to expect one. To the best of my knowledge, neither do Audi or VW (unless it's their top of the tree models (Q7, A8 Arteon etc) ?

it should be looked as design improvement

 

doesn't make sense, your lithium ion powered phone us in your pocket 

 

everything is prone to faults

 

Even Tesla's latest models use lead-acid 12v batteries to run auxiliary systems. Lead-acid may be old-tech, but they are reliable at extreme temps, can be partially-charged / discharged tens-of-thousands of times, can handle high-current draw, plus they are very cheap to maintain/replace.

You could argue that it’s a design “change” which does not necessarily mean it is an “improvement”. There are lots of examples of manufacturers trying to improve things only to make them worse.

 

The whole idea of moving to all-electric vehicles within the next 20yrs is a joke. Today’s technology is not capable of providing it and the advances it will need to get there enormous.

Where is all that lithium going to come from?

what viable alternatives are available in the quantities required to fuel the world?

How many new nuclear power stations would be needed to recharge the batteries, we all know how long it takes to build those? Without the infrastructure investment all-electric vehicles will never become mainstream.

 

Whoops! Excuse the rant, too many espressos today. I’ll end it now as the battery in this iPad is getting quite warm ;0)

 

Back on topic, please.  This thread was about the engine's "innovative thermal management system".

still on subject; technical discussion on technical thread

 

perhaps Tesla do install lead acid batteries but suspect for smaller things like car interior

 

lithium ion batteries and 48V system should be looked as design improvement, excellent article on the benefits;

Improved alternator's charging duty and help reduce the load on the engine, increasing fuel efficiency 10%>, more instant torque, i also red separately that it can electrify and drive turbo rather than depend on exhaust gasses driving it giving again smoother faster acceleration.....

I thing the "electrify and drive turbo rather than depend on exhaust" etc. refers to the 128 hp version, not the 148 hp one. 

Any advancements to ICE technology are just a short-term stop-gap. The medium-term technology will be Full Electric Vehicles, so expect to see less and less development of fossil-fueled wheeled transport.

 

Of course, safe mass-production, transportation and disposal of so much Lithium-Ion will create it's own problems, but at least monkeys will begin to feel a little safer from those VAG employees wearing white coats. VAG are certainly doing their bit to kill off diesel and petrol sales asap.
