On the cars considered in the present manual the compulsory thermostatically controlled cooling system of elevated pressure is installed (see rice. Cooling system device).
Circulation of liquid in the engine is provided with the centrifugal pump mounted in a forward part of the block of cylinders. Liquid flows round cylinders and goes to a back part of the engine. Further liquid proceeds in the cast channels of the soaking-up and final collectors, in cavities about spark plugs and the directing plugs of final valves.
The thermostat with the extending (paraffin) working body is mounted near transmission and closed by a cover. At an engine warming up the thermostat is closed and cuts a liquid stream from a radiator. After warming up of the engine up to the normal working temperature the thermostat opens therefore liquid comes to a radiator in which liquid is cooled and again the engine arrives.
The cooling system is connected with the atmosphere a radiator stopper in which there is a control valve. Such design provides increase in a boiling point of liquid and efficiency of cooling of liquid in a radiator. If pressure in the cooling system exceeds the level at which the sprung control valve of a stopper of a radiator works, then under the influence of pressure the valve rises from a saddle and a part of liquid flows through a perepuskny pipe in an additional broad tank with cooling liquid. When cooling system excess of liquid flows down back in a radiator.
The tank thus, supports liquid level in system and at the same time is the tank for reception of superheated liquid.
The cooling system of this kind is called closed as the liquid following via the stopper valve remains for further use.
System of heating
Heating are a part of the system the fan and a radiator mounted in the uniform case under the right part of the forward panel of a body, hoses of a supply and removal of cooling liquid from the cooling system of the engine and the control panel of heating/cooling of air in salon brought to the forward panel of a body (see rice. The heater block, block of the fan and conditioner mounted under the forward panel of a body). The cooling liquid heated from the engine proceeds through a heater radiator. The mode of heating is set by opening of the gate therefore the case of a heater is reported with space of salon. The switch on the control panel provides management of operation of the fan which blows in a radiator therefore there is an air heating.
Air conditioning system
Air conditioning system consists of the condenser mounted before a radiator, the evaporator installed near a radiator of a heater, the compressor mounted on the engine, a moisture separator with the reducing valve of high pressure, the hoses and pipelines connecting all specified units.
The fan directs an air stream from salon to a radiator of the evaporator on which there is a return of heat from air to coolant. In a radiator of the evaporator there is a boiling up of coolant to production of steam of low pressure and selection of heat in process of removal of steam from a radiator. The compressor provides circulation of heated coolant, keeping its elevated pressure, from the evaporator in the condenser where there is a coolant cooling, and back in the evaporator.
