Fig. 420. Piston sections. By an arrow the combustion chamber is shown




Fig. 421. A piston and rod kind: 1 — piston rings; 2 — the piston; 3 — a piston finger; 4 — a lock ring; 5 — a rod; 6 — an adjusting pin; 7 — the bearing loose leaf; 8 — the block of cylinders; 9 — a cover of the bearing of a rod; 10 — маслоразбрызгивающая an atomizer; 11 — a bolt, 10 Нˇм; 12 — a rod bolt




Details of shatunno-piston group are shown on fig. 421. The section of the piston of diesel engine TDI is shown on fig. 420. The form of the chamber of combustion of type ŤOmegať (ковшеобразная). For removal of pistons it is necessary to dismantle the engine and a head of the block of cylinders.
Fig. 422. A kind of the top part of the engine. By arrows the big dredging for inlet valves which are differently located on pistons № 1 and 2, № 3 and 4 are shown





After removal of a head of the block of cylinders pistons look how it is shown on fig. 422. Each piston has larger dredging for the inlet valve, however, they not all are located on one party. Deepenings on the piston for cylinders № 1 and 2 are located more close to the party of a flywheel, deepening on pistons of cylinders № 3 and 4 — is closer to the party of pulleys. For this reason new pistons have the labels of 1/2 or 3/4 put on them that you knew, in what cylinders they can be established. If it is required to remove pistons before it it is necessary to mark their position, having put on them numbers of cylinders. Wrong installation of the piston can lead to engine damage.
