I’m not talking about the unstable power grid, which fails 3-4 times a day on average. Just like that, the power goes out. But somehow it no longer bothers me. When the air conditioner beeps briefly or the lights come on in the evening, you know the power is back.
It’s the same with my job here regarding cars.
Since I won’t be here forever after all, I copied the table of contents of the book and sent it to the participants with the question: “What are you most interested in, what should we talk about next week?”
Named were:
- Data communication in the car
- air conditioning
- Ignition / ignition system
Data communication was easy, I know my way around that. I think it helps to know the difference between direct connection of sensors to ECUs, LIN, CAN and Flexray. Whether they remember the transmission speeds or the structure of the individual messages is not so important. What is important is that there are data buses. Errors can be found with an oscilloscope or diagnostic computer.
With “ignition systems” I was so focused on the content that I didn’t think much about whether it would help here. I was really well prepared, knew everything about ignition coils, the optimum ignition timing, optimum ignition energy, control by Motronic, characteristic diagrams or the different types of spark plugs.
At the third slide, someone asked.
“Is it the same with diesel engines?”
That’s right, now the scales have fallen from my eyes, that was really embarrassing.
All construction machines, excavators, buses, diggers, lorries have a diesel engine.
And of course it makes sense that all the cars in the fleet are also diesel. A uniform technology, only one filling station for all vehicles, makes a lot of things easier.
I also asked, don’t you have any petrol engines?
No, they don’t, not a single one.
After the last few years at the M, I’ve got it stuck in my head that “engines in cars are petrol engines” with at least 3 litres of displacement and at least 500 hp. I also know that there are BEVs, i.e. electric vehicles, which are the new cars.
But diesel? Why would anyone want a diesel?
Now I have to revise my world view. Here we only know diesel.
Just as the workshop procedures cannot be transferred from Germany – for example air conditioning.
At the end of the book there are always so-called workshop notes.
My clever book now said. “Never solder or weld the air-conditioning lines, but always replace them with new ones.
So everyone looks at me. “Why, we always solder them.”
I thought about it for a moment; it’s true, that’s the best thing they can do here.
First of all, the air conditioner is usually defective because a stone has damaged the pipe or something has come loose due to the roads. Then coolant escapes and the air conditioner no longer cools.
Then the labour time here is much cheaper than in Germany (about a factor of 30), but the parts costs are comparable. The labour time is “eh da – costs” because the people are there anyway.
And not to forget, when the lines are repaired, the car or machine is immediately ready for use again. The procurement of spare parts, on the other hand, takes a few days.
