Hello. I wanted to ask if this is true (I know that every menga is missing, but I just want to know if this is right at first): At high speed / load: With the camshaft adjustment one can open the inlet valve earlier (thereby also a valve overlap is created), so that one can still use the accelerator of the air column and on the other hand, (since every millisecond at high speeds is important, ) the “opening phase” of the inlet vent becomes The outlet valve can also be opened further, so that more exhaust gases can be pushed out. At low speed/load: The inlet valve can close later (also a valve overlap) so that the mixture can be pushed a little into the inlet channel again, so that less mixture is then in the cylinder overall and the engine is more economical, among other things. Or the inlet valve opens earlier so that exhaust gases can be pushed into the inlet channel and then works like an internal exhaust gas return. The effect is similar to when you close the inlet valve later. The outlet valve can be closed earlier so that some exhaust gases remain in the engine and then the stroke “artificially reduced”. The engine is also more economical. Sorry that all this was written differently. And as I said, I would like to know from you whether the task of camshaft adjustment is.
