| The pumping of pistons in a car engine firing up and down thousands of times per minute relies on heavy-duty lubrication. |
| This type of exhaust also significantly reduces the excess gasses after each exhaust stroke of the pistons. |
| A typical rebuild is new pistons, rods, main and rod bearings, piston rings, and a valve job. |
| The cams are mounted on a shaft which oscillates in rotation, and the pistons move so as to follow the profile of the cam. |
| On stripping the engine, it needed a rebore, 4 new pistons with rings and new bearings. |
| Its suit claimed that products from the pneumatics manufacturer infringed on two of his patents for magnetically coupled rodless pistons. |
