6.1. The general dataOn cars establish eight-cylinder diesel V-shaped engines with liquid cooling. Engines are located in a motor compartment is longitudinal.
Engine cylinders are cast from grey pig-iron for a single whole with the block of cylinders. Heads of the block of cylinders are made of an easy alloy and fasten to the block of cylinders bolts. In a head of the block of cylinders запрессованы steel directing plugs of valves. To the bottom part of the block of cylinders of the engine the two-section oil pallet in which flows down the oil necessary for greasing and cooling of the engine fastens.
In engines the scheme of a cross-section stream at which air arrives in engine cylinders on the one hand is used, and the fulfilled gases leave on the other hand the engine. Atomizers submit fuel directly to engine cylinders.
