General information about engines (VAZ-1111)

Engines of VAZ-1111 and 11113 models (figure 2 and 3), used in cars are 4-stroke carburetor, 2-cylinder with in-line, vertical cylinder arrangement and with a camshaft located on the cylinder head. These engines are identical in design and were developed on the basis of engines 2108 and 21083, so they have a high degree of unification (many identical parts) with engines 2108 and 21083. This mainly applies to parts of the connecting rod and piston group, valve mechanism, lubrication and cooling systems.

The larger working volume of the 11113 engine was achieved by increasing the cylinder diameter to 82 mm (like engine 21083). Therefore, engines 1111 and 11113 have different cylinder blocks, pistons, cylinder heads, as well as balance shafts, flywheels and generator drive pulleys. The carburetor on engines 11113 is installed with different calibration data.

The dimensions of the main mating parts of the engine and the limits of permissible wear during operation are given in Table 2.
