Problems solved by technology

These two methods have disadvantages. The first method can solve the problem of closed cycle icing in cold areas above -20°C, but it cannot solve the problem for environments below -20°C; Heating will consume the electricity consumption of the whole vehicle, affect the economy of the whole vehicle, and it is also prone to failure

Embodiment Construction

[0042] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and understandable, the specific implementation manners of the present application will be described in detail below in conjunction with the accompanying drawings.

[0043] In the following description, a lot of specific details are set forth in order to fully understand the application, but the application can also be implemented in other ways different from those described here, and those skilled in the art can do it without violating the content of the application. By analogy, the present application is therefore not limited by the specific embodiments disclosed below.

[0044] As described in the background technology, at present, many engines use a closed-loop breathing system. Under cold conditions, the blow-by gas in the crankcase has a high temperature and contains water, while the intake air temperature in cold areas is low (below -20°C), and the two air...

Abstract

The present application provides a device and method for heating an engine respirator, the device comprising: a controller and a first branch, the controller is used to receive the ambient temperature of the vehicle, the first end of the first branch is connected to the original oil return of the engine The circuit is connected and flows through the respirator, the second end of the first branch is connected to the fuel tank, and the controller is connected to the first branch; it is used to open the first branch when the ambient temperature is less than or equal to the first preset temperature threshold. Therefore, when the ambient temperature is too low, the oil return can be used to heat the respirator. Due to the high temperature of the engine return oil, the problem of icing of the respirator can be solved, and the vehicle’s electricity is basically not consumed, and the heat of the engine return oil itself is used for heating , reducing power consumption and failure rate.

Description

technical field [0001] The present application relates to the field of engine technology, in particular to a device and method for heating an engine respirator. Background technique [0002] At present, many engines use a closed-loop breathing system. Under cold conditions, the blow-by gas in the crankcase has a high temperature and contains water, while the intake air temperature in cold areas is low (below -20°C). When the joints of the air pipes meet, water will inevitably precipitate and condense, and then the wall will freeze, and gradually accumulate to block the pipe opening. After the joint is frozen and blocked, the pressure of the crankcase will rise rapidly, causing the oil dipstick to be pushed out, and the oil The oil in the bottom case is sprayed out, which eventually leads to serious failure of the cylinder and the tile. [0003] At this stage, there are mainly two ways to solve the above faults. One is to make the air pipe of the respirator into a flared pip...
