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 FUEL INJECTION e The throttle opening signal may be modified according to engine rpm and engine temperature. It can provide simplified cruise control. It can also control minimum rpm, replacing the idle-speed stabilizer, and control maximum rpm replacing the alternate-injector cut-out e But there's more. For traction control, the electronic throttle links with the ABS(Anti-lock Braking System). The same wheel- speed sensors of ABS also feed the ASR(Anti-Slip Regulator). e When any driving wheel starts to slip, a slight brake application prevents that wheel from slipping so much that the differential delivers no power to the other driving wheel. If both driving wheels show signs of slipping, the electronic throttle cuts back power for maximum traction. Traction control gives the car the max acceleration the tires can deliver to the road. If laying down tire smoke is your thing, avoid ASR, But for making the fastest takeoff, you cannot beat it. laying down主张,搁下,放弃beat冲击,敲打 trust相信,信赖
