ELECTRONIC FUEL INJECTION Electronic Throttle--Drive-By-Wire Some of the newest Motronic systems have an electronic throttle (also known as a drive-by-wire system). The electronic throttle has no mechanical link between the accelerator pedal and the throttle valve. Instead, as shown in the Figure on next page, an accelerator sensor picks up your movement or position of the accelerator pedal. It signals the control unit about pedal movement, and the control unit signals the servomotor on the throttle shaft to open The electronic throttle Bosch calls it EGAS) may sound like something none of us needs but it has many benefits sound like听起来好像Electronic Throttle—Drive-By-Wire Some of the newest Motronic systems have an electronic throttle (also known as a drive-by-wire system).
