Piston Rod
In a piston engine, a piston rod joins a piston to the crosshead and thus to the connecting rod that drives the crankshaft or (for steam locomotives) the driving wheels. Internal combustion engines, and in particular all current automobile engines, do not generally have piston rods. Instead they use trunk pistons, where the piston and crosshead are combined and so do not need a rod between them. The term ''piston rod'' has been used as a synonym for 'connecting rod' in the context of these engines. Engines with crossheads have piston rods. These include most steam locomotives and some large marine diesel engines. Steam engines The first single-acting beam engines, such as Newcomen's, had a single power stroke acting downwards. Rather than a piston rod, they used an iron chain. This could transmit a tensile force, but not a compression force pushing upwards. The piston was sealed in the cylinder around its rim but the top of the cylinder was open. Later, a rudimentary pist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
