i was in a new S class on saturday and it got me thinking,,,

what new toys will be coming on cars in the near future?

to get the ball rolling,,,,electrical brakes



electronic wedge system

 

fook that, what if the fuse blows

 

you crash

DUUUUHHHH

 

we have these in London already..........called cash points you just need a cash card

 

Seems but yet again, just more electronic gizmos to go wrong

 

1. Pneumatically operated valves (needs 42v electrical system), for CONSTANTLY variable valve timing .

2. Variable compression ratios (do a google search for the Saab idea ).

 

Those brakes are allready on teh new Mercedes.

We cant change teh pads easily as with the engine off teh brakes are locked on by the ECU. We need to tell the ecu to release the brakes so we can do a pad change and currently that requires a Mercedes computer.

 

 

completely different system Stu...

 

Fabulous system. Currently ready for production cars i believe.

 

How do you mean sir? I am talking about teh elctronic handbrake at teh moment, although i expect gareth has heard of some far more complex system knowing him.

 

Stu,

What makes it a fabulous system. I have no idea how it will even work. Obviously you do, so lets hear your thoughts mate

 

With no cams, you can tell the valves when to open at ANY rpm point. This means you have the PERFECT valve opening point at EVERY single RPM point. Obviously means the engine is efficient at EVERY point as it would be at it's BEST point with cams... More power, everywhere (apart from it's original peak) and better fuel efficiency .

 

it would mean the valve duration/lift wouldnt be determined by the camshaft..... and could be controlled by ecu

 

yes mate,,, completely electrical braking systems

mike ive seen the camless engine ideas,, they look amazing, and also read that bmw says they need 2kW of energy for them to work

the variable compression engine is also intresting,,,,, but a hidge on the block,,,, would be hard to keep it strong,,, even worse once we start winding loads of boost in

 

ahh too slow

 

no more cam belt failures

 

imagen that on a yb

 

also, as a caveat, seems to may be expensive if it fails?

 

when the cams has gone,,, the spark plugs will be next

 

You talking about the new four rota engine? I was saving that for later .

However, as you mentioned it - after you sir .

 

i did know what your on about mike but once you have no cams,, they will run the engines on self ignition like a derv engine! made also easyer with ion sensing equipent,,, which i think the new M5 is using

 

So an engine as we know it will sonn cease to exist. they gonna do away with the pistons as well next then will stick with my age old YB set-up thanks very much

 

interesting thread

so how do the electonic brakes work then

 

engines without pistons have been around years

the good old wankle engines



question on them anyhow, how do you lower the compression on them to fit a big turbo or can you just get away with a big turbo , injectors and ecu etc

 

being honest,, i dont know,,, ther is a actuator of somekind driving a wedge to create your clamping force

 

Not ones without spark plugs .

The Photodetonation Quasiturbine is quite similar to a rotary engine, but it has four faces on its rotor, rather than the usual three.

Photodetonation is a term for the compression-only ignition and combustion of a petrol/air mixture rather than the spark ignition of a traditional petrol engine. Petrol has a higher octane rating than diesel and is more difficult to ignite via compression alone. A conventional piston engine design would not be able to cope with the stresses, but the Quasiturbine apparently can. One of the benefits is a very clean exhaust as almost all the hydrocarbons are burnt . So this will obviously be pursued for ecological reasons...

 

good call mike

I remember years ago hearing about a electronic-esqe valve system by Lotus IIRC.

Anyone else remember that or am I talking shit again.

 

no mate,, i remember aswell,, im sure it used valves from the shuttle on it something like 15k a piece

 

Andy, give it time mate, this type of ground breaking technology takes its time getting over to Wales they will think its the best invention since sliced bread....if they get Hovis that is

 

Phewww! Thought I was wrong or summant.


All I could find from a quick Google.

what bread that is sliced??? fuck off,, thats amazing

 

42v is unlikley to happen, so camshaftless engines may have to wait a while until they go into production. of course there are companies that have them already as research engines - the carrot crunchers at lotus included

electric brake calipers enable far more braking force overall by individually apportioning maximum retardation to individual wheels - even those that are turned - and by allowing more bias to the rear than is currently used.

on the subject of brakes, carbon discs will increase in use

how about delphi's twin disc system? twice the braking torque in the same diameter package - ideal for the old skool 13"


in my area, there are already hybrid a/c compressors that have one mechanically driven scroll compressor, and one electrically. honda have been using these a while, and other companies are looking into it. means a/c can be run when engine is not running.

of course the next major step in propulsion will be hydrogen fuel cells, but i think that there may be more hybrid diesels first. i've already seen many hybrids designed for the Ultra Low Carbon Car challenge including citroen berlingo and smart forfour and fortwo. bizarre watching them drive silently about on electric power

alternative fuel engines will be more common, particularly biofuels

 

you alrerady get 2 capliers braeks on the rollers (and on some bttx cars from ages ago ( ithink it was aflahpa from 95?) and electronic brakes area already is use on buses, bu they are called retarders and operate on teh gearbox, some buses have 2 stage retarders and this savess on the brake pads too

 

....it's what makes time travel possible.

 

I think my dads Lexus hybrid already has this, I was wondering how the AC works when the electric engine is being used!

 

Phil possibly, or it could be a purely electrical compressor. i don't get to see much of what the competition are doing

 

the s class is gadget heaven..my old man has placed his order for the S65 AMG

 

amazing machine mate,, sadly the one i was in wasnt a AMG,, but a great car all the same,
