Working principle1. Electronic Throttle and Fly-by-wire ThrottleAlong with rapid development of auto industry, auto manufacturers in America,Germany, Japan and other countries successively adopted electronic throttle controlsystem early in 1990s. Electronic throttle control system mainly consists of throttlepedal, pedal displacement sensor, ECU (electronic control unit), data bus wire, servomotor and choker executing mechanism. Electronic throttle is generally adopted infairly new models. Electronic throttle is named in comparison with fly-by-wire throttlewhich features direct connection between throttle pedal and choker with thin steelwire. The treading depth of throttle pedal directly corresponds to the opening widthof choker. Electronic throttle is free of wire. Treading depth of throttle will be convertedinto resistance value after a potentiometer (with variable resistance) is mounted inpedal. Electronic system of automobile indirectly determines the depth of pedal throughsampling of resistance value. Finally, ECU will activate stepping motor to control theopening width of choker. It can be easily found through principle comparison that fly-by-wire throttle features simple system and direct control, with the proportion of theopening width of throttle and choker being 1:1. Characteristics of electronic throttleare as follows: throttle pedal only indicates driverт€™s operating intention, while thefinal right to control choker belongs to ECU.2. Characteristics of Electronic Throttle Control System and ECU(ECU)In models with electronic throttle control system, ECU will analyze the treading depthof throttle in combination with auto conditions when controlling electronic choker, andthen calculate appropriate opening width of choker at the current time. When diverspeeds up suddenly at the time of startup (tread the pedal to the utmost), ECU willperform analysis according to the current auto speed, opening width of choker andother factors, appropriately restrict the opening width of choker from the perspectiveof fuel saving and reasonable exhaust emission, and control fuel spray system torestrict maximum spray of fuel injection nozzle at the same time. In this way, driverwill feel that automobile begins to start after throttle is treaded for a while, which isthe so-called throttle lagging. Therefore, throttle lagging is actually the result of ECUoperation through restricting instant output of engine, which can make automobilemore environmental-friendly and energy-saving.3. Operating Principle of STRONG BOOSTER(1) Accelerating choker opening and improving static responseт€œAccelerationт€ of STRONG BOOSTER is realized mainly through improving the respondingsensitivity of choker. When ECU finds that driver has the intention for acceleration, itwill activate rapid opening of choker via circuit signals to improve the respondingsensitivity of throttle.(2) Speeding up throttle signals and improving dynamic responseWhen accelerator treads on throttle pedal, STRONG BOOSTER will calculate the alterationrate of throttle signals according to treading depth and time. Alteration rate is inproportion to accelerating requirements. STRONG BOOSTER will enhance such alterationrate and finally realize maximum dynamic response of auto acceleration.(3) Providing false driving style for ECUт€™s adjustment of engine parametersECU of modern engine generally has the capacity of self-adapting driving style. Ifdriver often treads on throttle quickly to a considerable depth (also known as pullingspeed), ECU will gradually consider that the driverт€™s style tends to be т€œviolentт€. In thisway, engine will slowly adjust choker and fuel spray system, etc. to obtain optimaladjusting parameters of engine under this style. After STRONG BOOSTER is used for along time, even if the driver drives the car with previous т€œmileт€ driving style, enginewill still acquire experience of т€œviolentт€ driving, which is equivalent to the adjustmentof ECU parameters. At the long last, engine will automatically amend its parametersto adapt to such driving style.Shipping Fee1.
