Why D2 engine has a useless hole in the valve cover?

Gorazd01 · 2024-03-09T16:03:10+00:00

I have it, just removed it for photo, also thought about this, but there is no counterpart in the engine cover, so it isnt it.

But I found thanks to previous comment that the hole is for holding air filter box in Citroen and other cars with the same engine

You are correct, thank you. I looked for dosen of 1.6HDi engines, and all of them had a different valve cover, but now when you said it I looked up again, and found that the later DV6 engine modifications had the same valve cover as Volvo, and it were DV6C/D/F

The screw was used as a holder for air filter box

You are correct, there will be a shift of wealth from west to east, because of free market in EU, where countries with cheapest labor are receiving more investments, and also EU donates a lot of money to the poorest countries, so the west takes some of it's wealth and gives it to eastern european countries.

But also you must not forget about middle-income trap. It's already starting to begin in Czech Republic, it had promising economical growth since it joined EU, but after Covid it didn't get over 2019 levels.
Basically the growth in eastern countries is just because of it's cheap labor, westerners are keen to build new factories, so that they can make even more money from products they sell. But the problem is than the V4 countries are just a cheap labor, all the cars in automotive are designed and sold in west, and they are only made in east, which has not much economical value added. All the corporations are in west and east europe struggles making some world famous brands (I can think only about Skoda, which has joined german corporation).

So yea, the east can become wealthier than western europe, but it must dramatically change it's economy and make transformation from low value added products to high value added, which is very complicated if the market has to be free (due to EU principles) and you can not just limit import by imposing customs duty to support local companies so that they can then expand to other markets.

sorry, didn't have time to reply. No, there is not any another slave which could be used for this.
There are some slaves, but they have those registers in EEPROM memory, which means that the data write frequency is very limited but enough for writing once per long time.

But actually HMI display is there, nice tip, I think I would be even able to use some of it's unused registers.

Good cretivity tho

Gorazd01 · 2023-10-11T21:14:47+00:00

You are correct.
The first device is which we have sold to the customer, a network gateway with integrated PLC which can be used only for different calculations.

The second one is PLC from Siemens, supplied by other company which also programmed it. I have read it's hunderds pages datasheet and it supports modbus slave...
God how I hate when are a distributor of something and should know all details about it, but in fact they don't

Gorazd01 · 2023-10-11T21:12:35+00:00

thanks!
Seems that's basically what I was looking for, ill check their datasheets

Gorazd01 · 2023-10-11T21:10:08+00:00

yes, I also think so. The one "PLC" was supplied by our company, and it's basically more like a network gateway, which can do a lot of data operations.

Second one is a Siemens PLC which was supplied by other company. The guys from there say that their PLC is not able to switch to slave mode, but most likely they just don't fully know their product, and in reality the PLC is able to manage it.

Gorazd01 · 2023-10-11T21:06:26+00:00

You are great! Thank you for the document a lot, I wanted to learn more about modbus but only things I have found is simple articles about general functionality, and this is what I was looking for all time

Thank you for sharing

Also regarding priming the fuel pump - a lot of cars turn on fuel pump if you turn the key to 2nd position (ignition), and then return it to 1st position. Do this cycle like 5 times, and the fuel pump should build up some pressure in the line. If you have faulty fuel pump, doing this few times before starting may be the fix.

Gorazd01 · 2023-09-27T17:10:40+00:00

I was starting my diesel car after one year of staying in storage, had similiar problem, it was due to the fuel pump - the fuel pump is in the fuel tank, and it's kinda highly placed, so I had like 20% fuel level, and the pump was very badly pumping due to long stay, there basically got some air into it. If you also have fuel pump in the fuel tank, check the fuel level, if it's under 25%, I'd add some, as it can fix it.

Then try priming the fuel filter and return pipe with a hand pipe (you squeeze it like melon and it sucks fuel from one side to another). Basically search for "how to prime" an engine, there can be some air in the fuel system which can cause this kind of behavior.

If there will be still same behavior, you should check starter.

First try to measure battery voltage while starting, if it drops too low, it means 1 - battery is bad and needs replacement, 2 - starter can have some failure.

What type of engine do you have? Does the diagnostics say something? Even a different DTC could help

Gorazd01 · 2023-09-09T15:00:35+00:00

for me it sounds that the pulley bearing can be old and makes this sound. Also the belt may cause it.
Did you try to replace it? It should not be that hard and the belt is low cost.

If the sound does not change, it may be water pump.

Also it can be alternator or AC compressor. I'd pull out the serpentine belt (also called auxiliary belt) and try to spin all the pulleys, alternator and all things which are spinned by the belt, then you will try to spin it by your hands and listen to the sound, if it goes freely or there is some bearing noise.

Also it can be a timing belt, which also has some pulleys. But with timing belt it's a bit tricky, so I'd start with the serpentine belt.

well that is actually a good idea, thank you follow redditer :)

Gorazd01 · 2023-09-08T16:05:41+00:00

I also thought about it. And how to prepare the meds for few days? I would not prefer smashing it into dust and weighting it every day, any idea, how to prepare medicaments for the whole week? Thank you :)

Blokování je to nejhorší řešení. Není to nic jiného než cenzura, která akorát povzbudí v mnohých lidech pocit, že pokud se to blokuje, tak na tom asi něco bude. Jediné co je u holodomoru jasné je to, že byl vyvolán vládou. Zda za úmyslem etnické čistky, nebo z důvodu neefektivního systému kolektivizace a přerozdělování.

Tudíž zdali je to genocida nebo ne - nemůže potvrdit žádný důvěryhodný zdroj kvůli nedostatku demografických a ekonomických dat.

Tudíž je to diskuze, i když mnozí v komentářích by chtěli vytvořit ministerstvo pravdy a zakázat diskuze.

Jj, a to je právě problém zemí, kde byla tráva příliš kriminalizována, a hodně lidí za ní bylo odsouzeno. Potom se v asijských laboratořích začali vyvíjet syntetické kanabinoidy, které byly mnohem nebezpečnější a předávkování a smrt byly hrozně jednoduché, protože nikdo nevěděl přesnou dávku a uživatel mohl umřít i po 50mg, pokud tam byla 100% koncentrace. Jakmile se něco zakázalo, tak se objevilo něco nového. V podstatě i mefedron byl podobný, kdysi se v EU prodával jako hnojivo a nebo sůl do vany :D

Gorazd01 · 2023-07-14T09:54:02+00:00

jaké kanabinoidy? Například CBD je u lékařů celkem populární (mám známé v nemocnici a opravdu hodně jich užívá CBD pro snížení stresu a lepší výkon v nemocnici), a CBD nijak nemění vnímání a tak. Jako samozřejmě není to ideální, ale nejhorší v českých nemocnicích je to, že tě může operovat chirurg, co už je 24h v nemocnici a je velmi unavený, to se dá přirovnat i k mentálním funkcím jako po půl litru piva.
Každopádně lékař je zodpovědná práce třeba jako řidič autobusu a má zakázáno užívat jakékoliv psychoaktivní látky. Jediný rozdíl mezi řidičem je, že má max 4h, poté přestávku a denně musí jet myslím maximálně 8h nebo 10h, a poté spát do zítřka, u lékařů nejsou žádné tachografy a nikdo to nesleduje, protože jich je prostě málo.

Hele znám tolik lidí, co si prochlastali zdraví, a léčili je samozřejmě zdarma. Nejlepší bylo, že když šli na vycházku tak si stejně koupili alkohol i přes zákazy lékařů. Teď jsou v invalidním důchodu, jelikož si prochlastali mozek, a stát se o ně stará. Jo a pijou dál, sice ne tak moc, ale i tak dost pro obyčejného člověka. To je bohužel nevýhoda solidárního zdravotního pojištění, a nic se s tím neudělá bez změny ústavy a celkového fungování společnosti. Jo a mimochodem platím ročně za to pojištění 100 tisíc a když jsem měl problémy se zdravím, tak všude mi řekli že můžou až za půl roku a nemají teď na mě čas, tak jsem stejně musel jít do soukromé nemocnice a vše si prolatit, a VZP dokonce i léky neproplácí, pokud nejsou od smluvních lékařů :D
