From the old cars to new ones, under the hood, one difference or i should put it : one gradual transformation is quite evident. The replacement of mechanical components by electrical ones. More and more mechanical parts are being replaced by electronic ones. For the simple reason, that unlike mechanical parts , electrical ones are not prone to error and do not require frequent tune-ups.For example mechanical fuel pumps are replaced with electrical ones, for fuel injection : carburetor replaced with throttle body + EFI(Electronic Fuel Injection) , Distributor + Distributor Cap replaced with independent ignition coils directly under ECU. etc.More importantly, with sensors monitoring many things.
I imagine, that in the coming years. We might see the replacement of the camshaft with something(?) that shall allow the ECU direct interface with the opening and closing of valves.That something(?), will allow the ECU to initiate variable valve timing to such an extent , never possible before .Consider the possibilities?. But, then thats just my imagination!! |
