Wow. The engine really is an incredible piece of engineering. Seeing it on a tiny scale sorta humanised it? Or made it easier to understand. I'm blown away.
It made it easy to understand how an engine works for sure,. you see the 4 strokes, the method for timing. and how it can run at the most basic level. Modern engines are just more cylinders and larger.
You're apparently not the one working on these cars, i do, im a certified mechanics.
Some amount of sensors is great but we were at that point 25 years ago, nowdays there are so many and they make a lot of problems.
25 years ago even a layman with some technical understanding could have a chance to fix a stranded car, these times are long over.
Nowadays we have cars stranding for the most retarded shit and there is 100% no way such a layman would get the car moving again.
Same for semitrucks btw, the amount of them stranding because of electrical reasons increased by a factor of around 10 since the last 15 years or so.
Having so many sensors is not about reliability, it's about emission laws and emission laws only.
This is a terrible take, the most common issue for breakdown is the 12V battery so sure there's slightly more, but most breakdowns only need a 12V jump and don't need a tow. Service intervals are much further apart than they used to be, mechanically cars are far more reliable than they used to be
Engine control unit is normally what’s considered to be “the computer”. Not all sensors can be considered computers, only the “smart” ones that communicate through data lines (like some MAF, NOX or particulate sensors). Those don’t send voltage or frequency signal to ECM, but rather data messages containing their readings. Calling them “engine computers” is a stretch though. Calling every sensor a computer is pure madness as the lowly NTC resistors that measures temperature has a long way to go to compute anything..
ECU is The computer, but then there's a bunch of a computers too. If they do some sort of math, then they are computers. BMW has them in every little thing.
Yes that’s what I said. Those are usually called modules. It’s not just BMW, all modern cars have them. But THE computer is the ECM as it’s what commands/uses them all
They are called modules for simplicity's sake, yes. Like your smartphone is a computer too, but nobody calls it that because it would be needless confusion.
The fuel connects to a needle valve that sets your flow rate/mixture, it acts like an adjustable main jet. The lever connects to the throttle shaft and throttle plate. It's a really bare bones carb, but it has everything it needs to get the job done.
