5.2.1. Block of cylinders


Fig. 3.5. Details of the block of cylinders and krivoshipno-conrod mechanism: 1 — the top compression ring; 2 — the lower compression ring; 3 — an oil scraper ring; 4 — the piston; 5 — a piston finger; 6 — a lock ring; 7 — a rod; 8 — connecting rods; 9 — a cover of the lower head of a rod; 10 — an arm; 11 — the block of cylinders; 12 — laying; 13 — the holder of a back epiploon of a bent shaft; 14 — a back epiploon; 15 — a flywheel; 16 — a back cover of the block of cylinders; 17 — an opening stopper for discharge of cooling liquid; 18 — the aligning plug; 19 — a bent shaft;
20 — an insert of the third support with persistent fillets; 21 — covers of radical bearings of a bent shaft; 22 — an insert of radical bearings of a bent shaft


the lok of cylinders (fig. 3.5) is cast from cast iron for a single whole with cylinders. On diameter cylinders are broken into five dimensional groups specified by figures on the top face surface of the block opposite to each cylinder from TNVD. Dimensional characteristics of the block of cylinders are presented in tab. 3.1. Check of technical condition and repairs of the block of cylinders of the diesel engine is made similar to indications of the corresponding subsection. "Petrol engines".
