The principle of _1_is as follows. When the engine starts, the oil pump _2_starts to work. It supplies oil through the filter, through the cylinder _3_to the most loaded units of the unit - to the bearings of the crankshaft and camshaft. The components receive _4_through slots at the crankshaft main bearing. The oil flows by _5_into the sump along the grooves in the cylinder head. This closes the circuit. In parallel with the lubrication of the key parts of the unit, oil _6_through the holes in the connecting rods and then splashes into the piston and the cylinder wall. Thanks to this_7_, heat is removed from the pistons, and the friction of the o-rings on the cylinder is also reduced. However, many motors have _8_different principle for lubricating small parts. In them, the crank mechanism breaks the drops into oil dust, which settles on _9_parts. In this way, they receive the necessary lubrication thanks to the microscopic _10_of lubricant formed.
