Topside V-compression firmly holds rope.

上部的V -压缩坚决持有绳。

When you start a V-8 engine, you are only driving two cylinders (1 liter) through their compression strokes, but with one big cylinder you would have to compress 4 liters instead.

当你启动V - 8发动机时，只是通过压缩冲程驱动了两个气缸(1升)，但是如果是一个大气缸你必须要压缩4升。

Multiple V-ring packing, combined with live loading, maintains packing compression under high-cycle and severe service applications.

多重V形环填料，组合动负载，维护填料压缩，适用于使用频率高，环境严酷的应用场合。

And you only have to look under the hood or crawl beneath the car to see a technological nightmare: A low-compression flathead V-8, cloth wrapped wires, a crude carburetor, leaf springs and no shocks, big mechanical brakes that were about as useful as an anchor, and a differential the size of a melon, to appreciate that this car was a polluting, rattling, death trap.
