Embodiment Construction

[0016] After the engine is started, it is in a cold running state. At this time, the coolant is in a small cycle, and the coolant should be prevented from circulating through the radiator (large cycle). The inner pipe of the thermostat is in the initial state, and the coolant flows from the engine water jacket through the thermostat small circulation interface to the circulation pump for small circulation (see figure 2 ). After the engine runs for a period of time, when the coolant in the water jacket reaches a certain temperature (this temperature can be set according to the specific engine), the ECU sends a signal to the drive module, and the drive module controls the stepper motor to rotate through an angle to drive the inner tube to rotate At one angle, the large hole on the inner tube is aligned with the large circulation interface on the shell, so that the coolant flows from the engine water jacket through the thermostat large circulation interface to the radiating water ...

Abstract

The invention provides a busing type electronic thermostat for a cooling liquid circulating system of an engine (see chart). The electronic thermostat is characterized by comprising a thermostat shell, an inner tube, a transmission shaft, a motor, a gear, a driving module, an ECU and a water temperature sensor. The water temperature sensor transmits a water temperature signal of the engine to the ECU, and the ECU controls the motor through the driving module, so the rotating angle of the inner tube is determined, large circulating cooling liquid flow is controlled, the cooling liquid temperature of the engine is adjusted, the engine after starting reaches a normal working temperature quickly, the abrasion of the engine is reduced, the efficiency of the engine is improved, the pollution when the cold engine runs is reduced, and the engine works in an optimal temperature state is ensured.

Description

Technical field [0001] The invention provides a sleeve type electronic thermostat, which belongs to the technical field of engines. Specifically, the present invention uses the motor to control the rotation angle of the inner pipe of the thermostat, change the coolant flow rate, and control the engine coolant temperature, so that after the engine starts, it reaches the normal temperature quickly, reducing engine wear and improving engine efficiency. , To reduce the emission pollution when the cold engine is running, and to ensure that the engine works at the best temperature. Background technique [0002] After the engine is started, it is in a cold running state. At this time, the coolant should be prevented from circulating through the radiator (large circulation), and the state of small circulation should be maintained to make the engine reach the normal operating temperature quickly. Therefore, the cooling system is installed in the engine cooling system. Device. However, t...
