Problems solved by technology
[0004] (1) When there is white smoke in winter, keep running the machine. Although the white smoke disappears after warming up, it consumes a lot of fuel, which is neither economical nor low-carbon and environmentally friendly.
[0005] (2) In summer, the water temperature is too high, and the phenomenon of "boiling" occurs, and the engine cannot work after automatically turning to idle speed, which affects production efficiency
[0006] For this reason, it is urgent to propose an engine temperature control system for construction machinery, which has solved the shortcomings of existing engines that need to be warmed up when the temperature is low and / or need to automatically idle when the temperature is high.

The invention discloses engineering machinery and an engine temperature control system of the engineering machinery. The engine temperature control system comprises a temperature sensor and a controller. The controller receives temperature information sent by the temperature sensor, the temperature information is compared with a preset temperature value, and control information is generated and sent according to a comparison result; the engine temperature control system further comprises a first blind window, a first drive device, a first transmission device, and / or comprises a second blind window, a second drive device and a second transmission device. The first blind window is arranged on an air inlet of a radiator, the first drive device receives the control information and runs according to the control information, and the first blind window is pushed to be opened and closed through the first transmission device. The second blind window is arranged on a top cover and / or a covering part of an engine, the second drive device receives the control information and runs according to the control information, and the second blind window is pushed to be opened and closed through the second transmission device. According to the engine temperature control system, when the engine is started to operate, rising time of water temperature can be shortened, and / or it is avoided that because the environmental temperature is too high, the water temperature is too high, and then the 'boiling' phenomenon occurs.
Description
technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature control system for an engineering machinery engine and an engineering machinery equipped with the same. Background technique [0002] When the engine used in construction machinery is started when the temperature is low, it is easy to cause white smoke, and the white smoke may last for a long time, resulting in a decrease in engine performance. If the flame is turned off, it will seriously affect the work efficiency. At present, for this situation, it is generally not to work immediately after starting the engine, but to allow it to run after idling warm-up and warm-up. In addition, when the engine for construction machinery is operating at high temperature in summer, the water temperature is easy to alarm, and the phenomenon of "boiling" appears. Generally, the machine has an automatic protection device, which will automatically alarm if the water tem...
