High-efficiency and energy-saving automobile thermostat and automobile engine assembly

Abstract

The invention relates to the technical field of automobiles, in particular to a high-efficiency energy-saving automobile thermostat and automobile engine assembly; including a controller, a temperature sensor, a heater and a three-way valve installed on a circulation pipeline in the cylinder head; the three The bypass valve is provided with a bypass valve head corresponding to the stopper of the water inlet of the water pump pipe and the main valve head corresponding to the stopper of the water inlet of the radiator pipe. The water passing gap is provided between them, and the water passing gap is connected with the cylinder head outlet pipe; through the temperature sensor, the controller and the heating, the movement of the thermal expansion jacking piston is controlled to realize the timely circulation of the circulation channel. Switching, to cool down the engine, realize automatic change of the circulation range of the coolant, avoid the premature opening of the valve of the existing automobile thermostat, make the engine temperature too low, or delay the opening of the paraffin valve, and cool down too late, causing engine damage and energy consumption waste.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a high-efficiency and energy-saving automobile thermostat and an automobile engine assembly. Background technique [0002] The car thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes the water circulation range to adjust the heat dissipation capacity of the cooling system to ensure that the engine works within a suitable temperature range. The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal operation of the engine. When the temperature of the cooling water is sufficient to cool down the engine, the main valve head of the thermostat and the water inlet of the radiator pipe correspond to stoppers, and the circulating water flowing out of the cylinder head outlet pipe of the engine enters the water inlet of the water pump pipe, and is pumped by...

AI Technical Summary

Problems solved by technology

When the temperature of the cooling water is sufficient to cool down the engine, the main valve head of the thermostat and the water inlet of the radiator pipe correspond to stoppers, and the circulating water flowing out of the cylinder head outlet pipe of the engine enters the water inlet of the water pump pipe, and is pumped by the water pump. Circulation is pumped into the engine to cool down the engine; when the temperature of the cooling water is high, the bypass valve head of the thermostat and the water inlet of the water pump pipe correspond to stoppers, and the circulating water flowing out of the cylinder head outlet pipe of the engine enters the radiator The water inlet of the pipeline enters the engine after being cooled by the radiator to cool down the engine; if the main valve head of the thermostat is opened too late, it will cause the engine to overheat; if the main valve head is opened too early, the engine warm-up time will be prolonged. make the engine temperature too low

Traditional thermostats are mainly wax-type thermostats. The opening of the main valve head is adjusted by changing the shape of the paraffin. There will be a certain delay in the melting of the paraffin. Long-term use will cause engine damage and waste energy.
