發(fā)動(dòng)機(jī)制動(dòng)工作原理

1、Why use retarders?為什么要使用發(fā)動(dòng)機(jī)制動(dòng)裝置為什么要使用發(fā)動(dòng)機(jī)制動(dòng)裝置Service brakes wear much faster once hotAnd, they become less effective as they heat up.整車制動(dòng)鼓在高溫狀態(tài)下磨損的非整車制動(dòng)鼓在高溫狀態(tài)下磨損的非?？?，并且可靠性下降。?？欤⑶铱煽啃韵陆?。What an Engine Brake does: 發(fā)動(dòng)機(jī)制動(dòng)裝置的作用發(fā)動(dòng)機(jī)制動(dòng)裝置的作用Enables faster control speed能夠更快的控制車速能夠更快的控制車速Control Speed: The cons
