这期是Buell电喷系统解析系列专题的最后一期,主要为大家讲解动力模式以及排气阀与ECU的关系和工作原理。任何发动机都有最高转速限制,而不是大家想象的,是发动机无力了,所以转速上不去了。发动机转速限制目的是保护发动机。因为一般发动机转速表设置红区是提示驾驶者不要在任何情况下把发动机拉到那个转速,而不是国内常说的,买车时候要看发动机能不能进红。这种错误理论是在大江南北广为流传的。红区前其实马力与扭力的峰值点已经出现了,所以红区对于驾驶的乐趣是毫无意义的。一般民用发动机进红区后,其功率是下降趋势的。比赛
This issue is the last issue of the Buell EFI system analysis series, mainly for you to explain the dynamic mode and the relationship between the exhaust valve and the ECU and working principle. Any engine has a maximum speed limit, rather than we imagine, is the engine powerless, so the speed did not go up. The engine speed limit is intended to protect the engine. Because the general setting of the engine tachometer red zone is to prompt the driver not to pull the engine speed in any case, rather than the domestic often said that when buying a car depends on whether the engine can enter the red. This erroneous theory is widely circulated in the north and south of the Yangtze River. In fact, the peak of horsepower and torque has appeared before the red zone, so the red zone is meaningless for the pleasure of driving. General civilian engine into the red zone, the power is a downward trend. game
