Cylinder Deactivation - 4 Cylinders To 2 How & Why? COD ACT Tech.

[@EthanJackson98]

This channel is so under appreciated. The research you must do to create these videos is tremendous

[@torquecars]

Cheers buddy it is hard work and when you look at what I earn from the hours I put in it works out at less that $1.30 per hour!!!! I do it for the community not for profit so I'm pleased that people find these videos useful and interesting. it is also a way for me to answer the 100's of emails I get each week as i wouldn't be able to respond individually to them all.

Great informative video, thank you. I have 1.4 ACT (Skoda) and unfortunately I have the dreaded rattle. When ever 2 cylinder mode activates you can hear a rattle. I've been told in 2 cylinder mode the engine naturally vibrates more, which leaves you with a metallic rattle sound. I've don't a bit of research and the likely culprit is the actuator rod.

Thanks for interesting content! Good luck. 💐🙏🇮🇳

Just swapped an engine for my customer who has skoda 1.5 tsi .. Rattling from top end at 63000 miles. Full skoda history.

[@evensisftw]

Quite a few engines in the wild that control their throttle by adjusting valve lift and duration mechanically, which consequently means the butterfly valve is wide open all the time. Makes me wonder what benefits would be found in engines of this type.

[@derekburgess]

If you did this on a diesel engine, while it would have less impact on the volumetric efficiency, might it reduce the NOx, since there would be less excess oxygen available?

[@fredy000]

can you tune such an engine? like maybe I buy one and want stage 1, will cylinder deactivation work?

[@torquecars]

Yes these engines (1.4 1.5 TFSi) can be remapped or tuned and in most cases will still retain the deactivation. Talk to your tuner about this to discuss your requirements and expectations.

Oil temp efficiently high? Is not true my car does it before i am out off my street after a cold start. I can sure you oil temp is not warmed up.

[@turktrchollanda7962]

Totally useless stupid system COD ACT. Very not smooth driving.

[@stuarthall2523]

Very interesting as I’m about to buy a T Roc 1.5 with this tech. It all sounds good, but is it a matter of extra technology to go wrong?

[@AnthGott]

Thanks for the video. Ive just bought a 1.5 tsi, what sort of fuel economy do you get out of the audi on a long journey?

[@torquecars]

I get around 50-60 MPG on my 1.4 TFSi on a run, my best is around 70mpg, but around town and general driving it gives about 45mpg. Obviously these drop a lot if i drive it hard, but these figures are based on general driving with a few overtakes and faster sections. Bear in mind I also only use shell V Power, which does make a difference to me for economy.

[@AnthGott]

@@torquecars thanks I think I am going to try use Esso as it does not contain any ethanol.

[@torquecars]

That's certainly the key - avoiding Ethanol. Are you in the UK? We're up to 10% on non premium fuels.

[@AnthGott]

@@torquecars yes there are a few companies using ethanol even in the premium fuels

[@blakespower]

the only problem I see with my Mazda at least is that its always the same cylinders that are running or get deactivated. wont that cause uneven wear in the cylinders? should like alternate them evenly for more uniform wear edit: never mind the pistons continue

[@flemmingqvist8326]

Mazda is a master of details and reliability. Many details have been optimized to secure a smooth (as possible) running with only two cylinders in operation. This can NOT be obtained with several different operating modes. Cylinder wear is not what ruins an engine. Turbo chargers and wet timing belts should be your main concern. My 2,5 Mazda petrol engine has non of those selfdestructive features.

[@AnthGott]

Mine kicks in pretty much cold on 1.5 tsi DPCA

[@PeteRock1]

I just recently found your channel. SUb’d 😊 Would like to learn more about the Audi TTS and the EA113 engine (2015 TTS 8j Mk2) - What are things to do before tuning? - How to make it more reliable. (Plug upgrades?, ignition upgrades? Oil upgrades & types?) - Tuning the DSG Pro’s & Con’s - Are catch cans necessary?

[@torquecars]

2.0 TFSi = most of this still applies to the EA113 kzbin.info/www/bejne/eKOriqqjo8yMi8U Things to do before you tune kzbin.info/www/bejne/a2OpnGijabmnj9E Gearbox tuning and mapping (one specifically for DSG is planned for the future) kzbin.info/www/bejne/m6qze4mgpM6MrLs Catch cans are important on these, the carbon build up is a problem without kzbin.info/www/bejne/gJ2yh2yNrtJpjpI Some remove the EGR but I personally feel the catch can is the main culprit here.

[@agrubera75]

Car manufacturers should build 2 cylinder engines, why bother with a 4 cylinder one & make it run on 2 cylinders🤦‍♂️.

[@rige1646]

??

[@AnthGott]

Fiat have 2 cylinder

[@hoggieboy9769]

@@agrubera75 well what if your trying to pick up speed fast you want the other 2 , it's easier to make it stop using 2 then to add stress to a 2 cylinder trying to do more then it should

[@hamiltoncouple01]

Worst possible technology. Not only it doesn’t save any fuel, it puts stress on the pistons that have to do double the work pulling along the dead pistons. This technology was developed back in the 80’s and was no good then and no good now. It was developed to satisfy government fuel consumption regulations.
