Description

Anti-icing electric heating crankcase ventilation pipe

Technical Field

The utility model relates to an engine field especially relates to an anti-icing electric heating crankcase ventilation pipe.

Background

At present, the automobile emission regulation requires that the gas in a ventilation system of an engine crankcase cannot be directly exhausted to the atmosphere, and the existing method is to separate the gas in the ventilation system of the crankcase from oil gas and then connect the gas into an air inlet pipe (in front of a supercharger) of the engine. In addition to oil mist and combustion pollutants, certain water vapor is contained in gas components in the crankcase of the engine, and particularly, the water vapor generated by combustion is more in the gas engine. When an automobile runs in a cold area, a ventilation system of a crankcase is often frozen and blocked, so that the crankcase of the engine is unsmooth in exhaust, the pressure of the crankcase is high, engine oil leaks, and the engine oil can be sprayed out from an oil gauge seriously, so that the normal operation of the engine is influenced.

The above background disclosure is only provided to aid understanding of the inventive concepts and solutions of the present invention, and it does not necessarily pertain to the prior art of this patent application, and it should not be used to assess the novelty and inventive aspects of this application without explicit evidence that such contents are disclosed at the filing date of this patent application.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

As shown in fig. 1 and 2, the anti-icing electrically heated crankcase ventilation pipe is characterized in that: including crankcase ventilation pipe 1, temperature sensor 2 and ECU3, crankcase ventilation pipe 1 comprises epidermal layer 4, heat preservation 5, zone of heating 6 and inlayer 7 from outer to interior respectively, epidermal layer 1 is high temperature resistant corrosion-resistant plastic material, can improve crankcase ventilation pipe 1's life, the intussuseption of heat preservation 5 is filled with insulation material, plays the heat preservation effect and prevents the quick diffusion of the temperature in the crankcase ventilation pipe 1, be equipped with electric heating wire 8 in the zone of heating 6, for crankcase ventilation pipe 1 provides the temperature, electric heating wire 8 evenly divides in the zone of heating 6 of whole crankcase ventilation pipe 1 for whole crankcase ventilation pipe 1 is heated evenly, prevents to freeze because of certain position supercooling and causes whole crankcase ventilation pipe 1 to block up, electric heating wire 8 with ECU3 connects, inlayer 7 is high temperature resistant corrosion-resistant plastic material, the service life of the crankcase ventilation pipe 1 can be prolonged, and the heating layer 6 is controlled by the ECU 3; the temperature sensors 2 are distributed in the middle of the crankcase ventilation pipe 1; the heating layer 6 and the temperature sensor 2 are respectively connected with the ECU3, the ECU3 detects the temperature in the crankcase ventilation pipe 1 through the temperature sensor 2, if the temperature is too low, the ECU3 controls the electric heating wire 8 to be opened, the crankcase ventilation pipe 1 is heated, after the set temperature is reached, the ECU3 controls the electric heating wire 8 to be closed, the supercooling protection of the crankcase ventilation pipe 1 is realized, and the risks of freezing and blocking the crankcase ventilation system of water vapor in the crankcase gas in a low-temperature environment can be prevented.

The foregoing is a more detailed description of the invention, taken in conjunction with specific/preferred embodiments, and it is not intended that the invention be limited to the specific embodiments shown and described. For those skilled in the art, without departing from the spirit of the present invention, several alternatives or modifications can be made to the described embodiments, and all such alternatives or modifications should be considered as falling within the scope of the present invention.
