Temperature controller for engine

Abstract

The invention relates to an improved temperature controller for an engine, which solves the problem that the structure of the prior art is defective and falls short of ideal requirements when the prior art is used for regulating and controlling the working temperature of the engine; the improved temperature controller comprises a valve body, a worm wheel shaft, a temperature control actuating mechanism and an automatic control loop of a big cooling liquid circulating loop and a small cooling liquid circulating loop, wherein the worm wheel shaft is assembled on the valve body; the temperature control actuating mechanism is used for controlling the big cooling liquid circulating loop and the small cooling liquid circulating loop; the automatic control loop mainly comprises a microcomputer control mechanism; the main technical points of the improved temperature controller are as follows: the worm wheel shaft and the temperature control actuating mechanism are used for respectively controlling the big cooling liquid circulating loop and the small cooling liquid circulating loop, wherein the temperature control actuating mechanism is driven by a rack shaft engaged with a wheel gear arranged on the worm wheel shaft and comprises a big cooling liquid circulating control part, a small cooling liquid circulating control part and a tensioning spring. The improved temperature controller has the advantages of being reasonable in the structural design, being accurate and reliable in regulation and control, enabling the engine to be in the optimum working temperature state all the time when the engine operates in any atmosphere atmospheres, and obviously improving the operating performance of the engine, thereby reducing the consumption of fuels and the emission of harmful gases, fully increasing the capability of the engine for output the power and prolonging the service life of the engine.

Description

technical field [0001] The present invention is a divisional application with a patent application date of December 15, 2009, an application number of 200910220745.8, and an invention name of "engine temperature controller". [0002] The invention relates to a control device for improving the operating temperature of an engine, in particular to an engine temperature controller for keeping the engine running at the optimum operating temperature, reducing fuel consumption, reducing harmful gas emissions, and prolonging service life, which belongs to the engine supporting part. Background technique [0003] As we all know, the engine can only exert its maximum working efficiency under the condition of maintaining the optimum working temperature (generally 85°C-95°C). Therefore, most of the engines work under the condition of temperature adjustment, trying to forcefully control the circulating water cooling system. To maintain the optimum working temperature. However, when the...
