Abstract
The invention provides a novel engine cooling system and belongs to the technical field of engines, and the system provided by the invention can be used for solving the problem of slow warming-up speed of the existing engine. The novel engine cooling system comprises a water pump and a controller. In the engine cooling system, a cooling liquid is ensured to circulate in a cooling liquid circulation passageway by virtue of the water pump so as to cool the air cylinder of the engine; the cooling system also comprises an air cylinder temperature sensor and a cooling liquid temperature sensor which are connected with the controller; and the controller starts up the water pump to drive the cooling liquid to perform circulation cooling when the air cylinder temperature and the cooling liquid temperature exceed the set temperature respectively. The novel engine cooling system provided by the invention controls the starting of the water pump by stages, circulation cooling is not carried out when the temperature is lower, the warming-up speed of the engine can be improved, and the loss of effective power for the water pump can be reduced; and cooling is carried out when the temperature is higher, the fuel pulverization of the engine is improved, and the harmful gas emission and fuel consumption rate of the engine can be reduced.
Description
Technical field
The invention belongs to technical field of engines, relate to a kind of novel engine cooling system.
Background technique
Some motors all are enclosed pump circulation cooling systems at present, water pump is forced cooled engine, take away organism temperature through circulating cooling liquid, the engine component warming velocity is slow, cooling liquid reaches the about 900s of operating temperature, and when motor was in temperature than the situation of hanging down, cylinder wall temperature was lower, fuel-oil atmozation is bad, and it is bad to cause burning; Coolant temperature is lower, and then lubricating oil viscosity is too high, and motor friction in pairs coefficient strengthens, and mechanical loss strengthens, the power moment of torsion of unfavorable motor; When coolant temperature was low, the controller control strategy needed, and identical air inflow need be sprayed more multiple fuel, and fuel consumption rate strengthens; The tradition cooling system all is disadvantageous to engine emission and fuel consumption rate.Present stage Abgasgesetz and the fuel oil laws and regulations requirement more and more higher, it is a trend that cooling liquid is rapidly heated.
Summary of the invention
The objective of the invention is at the slower problem of existing engine coolant intensification, and proposed a kind of engine-cooling system that the engine warm motor speed is provided.
Purpose of the present invention can realize by following technical proposal: a kind of novel engine cooling system, comprise water pump and controller, controller can be used for the working state of control of pump, this engine-cooling system circulates so that cylinder is cooled off cooling liquid by water pump in the liquid circulation runner, it is characterized in that, described cooling system also comprises temperature cylinder sensor and the cooling-water temperature transmitter that is connected with controller, and above-mentioned controller just starts water pump during all above separately setting temperature in temperature cylinder and coolant temperature and drives the cooling liquid cooling that circulates.
During low temperature, the controller control of pump does not turn round, and can improve the durability of water pump, prolongs the engine water pump service cycle simultaneously, reduces Cost of repair and maintenance, and motor can be rapidly heated, and reaches the purpose of rapid warming-up; When the temperature of liquid to be cooled and cylinder was elevated to setting value, control of pump started again, can reduce the motor noxious gas emission and reduce fuel consumption rate.
In above-mentioned a kind of novel engine cooling system, described temperature cylinder sensor is arranged on the cylinder cap, is used to detect the temperature of cylinder cap and will detects data transmission to controller.The temperature cylinder sensor can only detect the temperature of cylinder cap, is to flow from the cylinder body to the cylinder cap because cooling liquid flows to, and the temperature of cylinder cap is higher than cylinder body; And cylinder cap bridge of the nose district is a weakness zone, and it is overheated to be easy to generate, and is surpassing serviceability temperature for a long time, and the cylinder cap durability will descend.
In above-mentioned a kind of novel engine cooling system, described cooling-water temperature transmitter is arranged on close cylinder cap place in the coolant circulation passage, is used to detect the temperature of cylinder cap place cooling liquid and will detects data transmission to controller.
In above-mentioned a kind of novel engine cooling system, when cylinder cap place coolant temperature was lower than 95 ℃ and cylinder cap temperature and is lower than 125 ℃, the controller control of pump was not worked.
In above-mentioned a kind of novel engine cooling system, when cylinder cap place coolant temperature is higher than 95 ℃ and cylinder cap temperature and is higher than 125 ℃, the work of controller control of pump.
Compared with prior art, this novel engine cooling system is the startup of control of pump stage by stage, the temperature cooling that do not circulate when low, can improve the warming-up speed of motor, reduce the loss of the effective merit of water pump, improve engine power and moment of torsion, improve water pump durability simultaneously, prolong the engine water pump service cycle, reduce Cost of repair and maintenance.Just can cool off when temperature is higher, improve the engine fuel atomizing, can reduce the motor noxious gas emission and reduce fuel consumption rate; Water temperature improves and reduces lubricating oil viscosity simultaneously, reduces the friction of motor kinematic pair, further reduces fuel consume.
