General question about controlling car engine ???
I would like to ask, how do call the "thing" that control RPM of your engine ??? What I mean ... there is something - kind of small motor, that controls the RPM. When you start your engine and you don't have any gear it holds the RPM on cca 1000 RPM. But in winter (when the engine is cold) it brings the RPM to 1500 ... and then, when the engine becomes warmer, it decreases the RPM.
1. How do you call the part, that controls these RPM ???
2. Is there any restriction that says what is the maximum RPM that this "small motor" can provide... like it will not make more then 2000RPM ... or you could set it up up to 7000RPM as well ???
Thank you in advance...
