ZMZ-4061 engines, ZMZ-4063 — carburetor, four-cylinder, line with a microprocessor control system of ignition. The general view of engines is shown in fig. 4.110, 4.111. The cross-section of engines is shown in fig. 4.112.
The main design features of engines are top (in a head of cylinders) an arrangement of two camshafts with installation of four valves on the cylinder (two inlet and two final), increase in extent of compression to 9,3 at the expense of the combustion chamber with the central arrangement of a candle.
These technical solutions allowed to increase the maximum power and the maximum torque, to cut fuel consumption and to reduce toxicity of the fulfilled gases.
The pig-iron block of cylinders without plug-in sleeves having high rigidity and stabler gaps in couples of friction is used to increase in reliability on the engine the piston stroke to 86 mm is reduced, the mass of the piston and a piston finger is reduced, better materials are applied to a bent shaft, rods, bolts of rods, piston fingers, etc.
The drive of camshafts — chain, two-level, with automatic hydraulic natyazhitel of chains; application of hydropushers of the valvate mechanism excludes need of adjustment of gaps.
Use of hydraulic devices and forsirovka of the engine demand quality purification of oil therefore in the engine the full-line oil filter of the increased efficiency is applied ("superfilter") of single use. The additional filtering element of the filter excludes hit of the crude oil in the engine at launch of the cold engine and a contamination of the basic filtering element.
The drive of auxiliary units (the pump of cooling liquid and the generator) is carried out by a flat poliklinovy belt.
On the engine diaphragm coupling with the ellipsnonavity overlays of the conducted disk having high durability is established.
The microprocessor control system of ignition allows to correct an ignition advancing corner, including in the parameter of detonations at the changing power setting that allows to provide necessary indicators — power, economic and toxicity of the fulfilled gases.
