Engine thermolator assembly

Abstract

The invention discloses an engine thermolator assembly, which comprises a cover plate, a support, a jacking mechanism and a valve which is linked with the jacking mechanism, wherein the jacking mechanism comprises a sensing body, a sensing body cover, a rubber pipe, a push rod and a spring; a center hole is formed in the valve; a first shoulder of the upper end of the sensing body is located on the lower side of the valve; a limit shoulder is arranged on the lower surface of a main valve; a space in which the first shoulder can vertically move is reserved between the center hole and the limit shoulder; a stop block is arranged below the limit shoulder in the middle of the sensing body; the spring sleeves the sensing body; two ends of the spring abut against the stop block and the support; the upper end face of the first shoulder is closely attached to the lower surface of the valve; the upper surface of the valve is closely attached to the lower end of the cover plate. The condition that after the valve is opened, since the temperature fluctuation of cooling liquid is overlarge due to an overlarge flow area, the rotation speed fluctuation of an engine is caused is prevented, the vibration of the engine is reduced, and the oil consumption and the emission of the engine are reduced.

Description

Problems solved by technology

However, at the beginning of engine start-up or low-speed and low-load operation (especially in cold regions in winter), due to the temperature hysteresis of the engine thermostat itself, the valve can only be opened when the temperature of the coolant in the engine rises to a certain level. After the valve is opened, due to the large flow area, a large amount of coolant pours into the engine. After mixing, the temperature of the coolant in the engine drops rapidly, causing large fluctuations in the temperature of the coolant, causing fluctuations in the speed, and increasing the vibration of the engine. As a result, uneven combustion is caused, which is not conducive to vehicle fuel consumption and emissions, and reduces user comfort
