大连汽车用阀门之排气制动阀介绍： 排气制动阀：是一个辅助制动器，是汽车行车制动器的必要补充。排气制动阀将发动机作一个空气压缩机使用而产生制动力矩从而对汽车产生减速作用。一般安装在排气管中，在需要减速时关闭阀门以阻塞排气通道而达到制动效果。它主要使用在矿山或山区公路行驶的汽车或常在交通情况复杂的城市街道上行驶的汽车。 其作用是在不使用或少使用行车制动器的条件下，使车辆速度降低或保持稳定，但不能将车辆紧急制停。 排气制动阀主要用于柴油车，因为发动机压缩比比较大，作为空压机，其减速效果明显。 Dalian automotive valve exhaust brake valve: Exhaust brake valve: is an auxiliary brake, is a necessary complement to the service brake of automobile. Exhaust brake valve engine as an air compressor due to braking torque resulting deceleration of the automobile. Usually installed in the exhaust pipe, the need to slow down when valve is closed to block the exhaust channel and reach the braking effect. It is mainly used in mines or mountain road car or often travel traffic conditions in complex citycars on the street. Its role is not in use or less use of the service brake condition, the vehicle velocity is decreased or remained stable,but not the vehicle emergency stop. Exhaust brake valve is mainly used for diesel vehicles, because the engine compression ratio is relatively large, asair compressor, the reduction effect is obvious. |
