Abstract

The invention discloses an electronic temperature regulator assembly for a heavy diesel engine. The electronic temperature regulator assembly comprises a cover, a joint (5), a push rod (6), a large spring (7), a sensor (8), a valve seat (9), a valve (10), a small spring (11), a push rod lock (12) and a support (13). The valve seat (9) comprises a valve seat bottom plate (15) and a valve seat side plate (16), circulating holes (19) are formed in positions among support ribs (17) on the valve seat bottom plate (15), water can flow through the circulating holes (19), the valve (10) is of a cylindrical structure, the upper end of the valve (10) corresponds to sealing steps in the valve seat bottom plate (15), openings (20) are formed in positions among connecting ribs (18) on the lower end surface of the valve (10), the water can flow through the openings (20), the lower end of the sensor (8) is connected with the upper end of the push rod lock (12), and the lower end of the push rod lock (12) is connected with the connecting ribs (18) on the lower end surface of the valve (10). The electronic temperature regulator assembly has the advantages that the electronic temperature regulator assembly is reliable in performance and applicable to cooling systems of high-flow heavy diesel engines.

Description

technical field [0001] The invention relates to a thermostat for an engine, more specifically to an electronic thermostat assembly for a heavy-duty diesel engine, and belongs to the technical field of automobile engine cooling systems. Background technique [0002] The engine thermostat is connected to the pipeline between the car engine and the car radiator. Its function is to sense the temperature of the coolant, control the large and small circulation of the coolant, adjust the amount of water entering the car radiator, and keep the engine's working water temperature constant. At a certain temperature to ensure that the engine works in the best condition. Traditional engine thermostats are generally ordinary wax-type thermostats. The thermostat senses water temperature through paraffin, and uses the characteristics of paraffin to expand and contract with heat to move the push rod to adjust the opening of the thermostat valve. However, the thermostat with this structure i...
