Heat Exchanger

Fig. 4.87. Heat exchanger: 1 - withdrawal; 2 - supply of cold fuel; 3 - the thermostat; 4 - a casing of the thermostat; 5 - cylinder head; A - diesel fuel; B - coolant

The heat exchanger (Fig. 4.87) is integrated into the cooling system and is fixed to the side bolted to the cylinder head. It ensures safe operation of the diesel engine even at temperatures below -25 ?� C depending on the position regulator thermostat cooling fuel is fed through the heat exchanger. When the coolant temperature is below +18 ?� C, all of the fuel passes through the heat exchanger, from + 18 to + 30 ?� C - the mixing mode is enabled, while at higher temperatures, the fuel passes through the heat exchanger.
