The design of the air filter and throttle valve is shown in Figure 5.21.
Air filter with dry replaceable filter element (10) replaced when the maintenance indicator light comes on. With intensive use, in adverse natural conditions, it is recommended to replace it with a decrease in the period of its use to 15,000–20,000 km or less.
The intake of air to the combustion chambers occurs through a system of air channels - the intake manifold (3, fig. 5.22), having a variable length of the channels depending on the speed of the crankshaft.
Throttle valve on model engine «N62» serves as a backup node in the engine management system. The main power control unit is the system «Valvetronic» (see fig. 5.12).
