TSI ZMS: What is it?

Hello,

Please don't immediately criticize me, but I have a question from a rather unconventional perspective:
Do the 1.2 TSI engines with 63/77 kW or the 1.4 TSI engine with 90 kW (manual transmission, e.g., in the Golf 6) have a dual-mass flywheel (DMF)?

Background:
Today, while my 1.9-liter car was being serviced, I had the chance to test drive a new Golf 6.
I test drove the 1.2 TSI (manual transmission, 77 kW) and I'm still thrilled with it!
The surprisingly low possible speed setting really impressed me; there's no humming or jerking at all!
On the other hand, there's also only very limited acceleration when you...
Approximately 1200 rpm in 5th gear when you press the accelerator - but that's what gears 2-4 are for, after all.
I had concerns about the accessibility, but I can tell you that...
"The first gear is short and crisp, which makes it easy to handle even on steep inclines."
It also doesn't immediately disconnect from the LLR.

Do you have any information specific to ZMS?

Thank you and best regards,

PD90

You would have had to ask the parts expert... if a dual-mass flywheel (ZMS) is offered as a replacement part, then he has one .

Well, you're right - I should have asked earlier...
I only started thinking about the machine in detail when I got home.
Sure, here is the translation of the text from German to English:

"Goodies:"

This phrase can be translated in a few different ways, depending on the context. Here are some options:

* "Treats"
* "Snacks"
* "Rewards"
* "Gifts"
* "Surprises"
* "Goodies" (as a general term)

For example, if you're talking about food items that are given to pets or children, you might use the word "treats." If you're talking about small gifts or tokens of appreciation, you might use the word "rewards" or "gifts." And if you're just referring to something that is generally considered to be good or enjoyable, you could simply use the word "goodies."

I hope this helps!
- no HFM
- No (external) EGR system, therefore no EGR cooler or bypass (no "dirt" in the intake manifold).
- No DPF/SCR system; instead, a widely proven three-way catalytic converter.
- SOHC (no variable valve timing, chain drive => simple!)
- Coil pack with short spark plug wires (spark plug replacement is a breeze!).
- The machine is tiny - even in the engine compartment of a Golf 6, there's plenty of space; you could almost fit yourself in there .

continue:
- No air/air heat exchanger, but air/water. This results in a very low dead volume and extremely fast response to positive load changes, even at low speeds.
I've only seen this before in the 8-cylinder TDI/CDI engines from Audi/Daimler. But even the 1.4 TSI with 90 kW has it too.
The only concern I have is that if this low-temperature coolant leaks, it could potentially cause damage if the vehicle sits overnight and then is started.
(That's why the engine is always manually cranked a few revolutions on the test stand in the morning, because the vehicle's intercooler system, which uses water to regulate the intake air temperature, tends to leak. And if you don't manually crank it in the morning before starting, the connecting rod can bend.)
- Electric actuator on the wagon. At least, this is a first for Volkswagen (but since electric actuators have been causing problems in ventilated trailers for quite some time, I think it should be reliable...).
- Direct injection: All the components together (high-pressure pump, injector) look quite small for their maximum pressure of about 250 bar, but they have been running reliably for a few years now.

For my part, I plan to continue focusing on diesel technology professionally in the future, but I will switch to gasoline engines for my personal vehicles.
"Euro6 combined with a DPF, SCR, NOx storage catalyst, high EGR rates, and MFB50-controlled combustion, as presented in the PSG documentation, seems like a lot for the customer who owns their vehicle."
Driving it beyond the warranty period is a bit "overly" complex and sensitive.

=> This is just my opinion, if it's too strong, just ignore it!

Here's another helpful link on the topic of the 1.2 TSI engine:

=> Very good video!

Greetings, PD90.

And what fuel consumption does this high-tech, small-engine powerhouse have when you really push it?

Consumption: In practice (based on my driving habits), it is currently unknown...

The 90kW 1.4-liter engine starts to produce noticeable torque at around 2500 rpm, and the 1.2-liter engine will likely behave similarly.
During long lectures and practice sessions on the training device (AB) in Germany, a significant amount of information is likely to be absorbed.
At speeds up to a maximum of 130 km/h, not much needs to be "cooled," so it's not quite as bad.

The high-tech engine's displacement is comparable to that of current 1.6 and 2.0 TDI engines when considering the effective average pressure, and in some cases, it's even slightly lower.
"Outliers are just my BXFs, which should last forever due to their low pressure."

The input values in the table are taken from the technical specifications of the current G6 model.
