| 2 | - | Piston cooling nozzles |
Injectors located in the cylinder block provide lubrication and cooling of the pistons and piston pins. These injectors spray oil into the piston, after which the oil, flowing through two internal wave-shaped channels, helps cool the piston head.
Lubricating oil is supplied through the cylinder block via the main oil line and channels in the block to all major moving parts. Through these channels, oil is supplied through holes made in the crankshaft to the main bearings and the bearings of the lower connecting rod head.
The turbocharger oil supply pipe is connected to a conical hole on the right rear of the cylinder block, under the right cylinder head, via a banjo connection. Thus, the turbocharger bearings are lubricated through the conical hole with oil under high pressure, created by the oil pump.
The cylinders are cooled by liquid flowing through the channels and cavities of the cylinder block.
The cylinder head is secured to the block by two hollow metal pins located at the rear on both sides.
On the left rear side of the ladder frame, below the turbocharger, there is an opening for the pipe that carries oil back from the turbocharger to the engine sump.
On the right front side of the cylinder block there are sealed plugs that close the oil passages. At the front and rear of the cylinder block there are plugs for the main line of the lubrication system.
