Engine cooling system
The function of the cooling system is to make the engine under any conditions have been moderate cooling, so as to maintain the appropriate temperature (coolant temperature) to work
What is the reason for poor car cooling system?
serious damage to the engine, wear increased
The purpose of the vehicle to pressurize the cooling system
When the coolant temperature below 80 ℃, the paraffin into a solid, the spring will be pressed on the valve seat, the valve closed, the coolant from the bypass flow into the air conditioning radiator inlet pipe into the radiator, that is, small cycle, The cooling intensity is small. When the temperature of the coolant is higher than 80 ° C, the paraffin wax melts into liquid and its volume expands, forcing the rubber sleeve to shrink, the upper end of the counteracter rod can not move up due to fixation, the rubber sleeve moves the shell against the elasticity of the spring, Valves, most of the coolant can enter the radiator along the radiator into the radiator for a large cycle, a small part of the coolant is still a small cycle, cooling system cooling strength increases
How long to clean the engine cooling system
Expert advice: At present, the engine cooling system, although most of the use of antifreeze, rust and descaling capacity of the antifreeze, but after a long period of use, due to chemical changes between substances, the performance of non-frozen liquid will gradually decline , The cooling system after a long period of use will appear in these three cases: First, the coolant salt in the system wall deposition to form a large number of scale, thus affecting the cooling system cooling capacity, resulting in water tank boil, the engine overheating, Power consumption and fuel consumption increased, etc. Second, the coolant and metal electrolysis and chemical reactions, so that the metal surface corrosion, the phenomenon of "cavitation", resulting in crankshaft, piston and piston ring early wear; When the coolant contains silicate, when the coolant temperature from high to low changes, the silicate will produce "differentiation" phenomenon, in the coolant to form a moss of the stripes, reducing the cooling fluid flow rate , The cooling function of the cooling system is reduced.
Computer host cooling system which is good
Water is cold.
What parts of the mobile cooling water system specifically refers to?
Mobile cooling water system definition: the station does not have fire water, fire when the fire truck from other water sources, through the car with a water hose and water gun for water cooling.
What is the working principle of a car cooling system?
The cooling system is part of the heat of the hot parts in a timely manner to send out to ensure that the engine in the most appropriate temperature conditions. Engine cooling with water cooling and air cooling in two ways, and now the general car engines are water-cooled. Engine water cooling system is mainly composed of water pump, radiator, cooling fan, compensation water tank, thermostat, engine body, cylinder head water jacket and other components.
Engine cooling system composition and working principle?
An engine is a machine capable of converting other forms into mechanical energy, including engines such as internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), motors, and the like. Such as internal combustion engine is usually the chemical energy into mechanical energy. The engine is suitable for both the power generating device and the entire machine including the power unit (eg gasoline engine, aero engine). The engine was first born in the UK, so the concept of the engine is also derived from English, its original meaning refers to the kind of "power of the mechanical device."
