Abstract
The invention discloses an oil-gas separator for automobile and engine of automobile, comprising shell, filter core and air duct in the shell, characterized in that a heat-tracing device is set round the shell on the radial direction. The heat-tracing device can effectively solve the problem that the ventilation system of crankshaft box of automobile is invalidation in high and cold region or cold season so that the normal work of engine is influenced. In hot season, when the temperature is more than 70DEG C, the resistance in heat-tracing device increases to infinity so that the temperature does not ascend and normal work of engine in various environmental temperatures is satisfied.
Description
Technical field
The present invention relates to a kind of motor car engine annex, more specifically to a kind of gas and oil separating plant of motor car engine.
Background technique
Generally, the gas and oil separating plant of motor car engine is formed by considering core and housing two-part, its effect is incendivity mixed gas and the waste gas with the cylinder internal leakage, by crankcase ventilation system inflammable mixture being sucked cylinder utilizes once more, prevent to make machine oil thinning after the vapor condenses in the crankcase performance depreciation; Simultaneously the compositions such as machine oil in the mixed gas are stayed in the gas and oil separating plant or by pipeline and flowed back to crankcase, this not only can improve the second use rate of fuel, more can effectively control exhaust emissions, reduces the pollution level to environment.
But, because contain water vapor and sulfur dioxide in the waste gas of cylinder internal leakage, when vehicle is in severe cold season or severe cold areas, the gas and oil separating plant content is prone to icing phenomenon, cause crankcase ventilation system to lose efficacy, water recovery simultaneously forms foam in machine oil, destroy the supply of machine oil, influences the motor proper functioning; And when high engine speeds turns round, very fast by the airspeed of gas and oil separating plant, because of vaporization heat absorption, can quicken the freezing process of water vapor in the waste gas greatly, when serious even lead to a disaster.
Summary of the invention
Technical problem to be solved by this invention provides a kind of gas and oil separating plant of motor car engine, and it can satisfy motor under low temperature environment, proper functioning.
For solving the problems of the technologies described above, the gas and oil separating plant of a kind of motor car engine of the present invention, a kind of gas and oil separating plant of motor car engine comprises housing, be arranged on filter core, the ventilation duct of enclosure interior, it is characterized in that: on described housing, be provided with companion's thermic devices.
Described companion's thermic devices is arranged between described housing and the lagging.
Described companion's thermic devices by heat transfer sheet and be located at heat transfer sheet and housing between accompanying-heat cable stick to one admittedly mutually.
Described accompanying-heat cable is on the housing axial direction, and type or cross type are connected on the housing in the shape of a spiral; On the axial direction of housing, rounded.
The technical program is in order to overcome when vehicle is in severe cold season or severe cold areas, the gas and oil separating plant content is prone to icing phenomenon, be provided with companion's thermic devices: when automobile ignition switch is closed, electric current from storage battery forms closed loop by companion's thermic devices, accompany this moment thermic devices to produce heat, and pass to each position of housing by even backing uniformly.
Technological scheme provided by the present invention can ensure motor under low temperature environment, proper functioning when running up, Ceng Qiang the reliability that under various environment, travels of vehicle.Simultaneously simple in structure, technology is easy to manufacture.
Description of drawings
Fig. 1 is the structural representation of described gas and oil separating plant.
1 is housing among the figure; 2 for considering core; 3 are companion's thermic devices; 4 accompanying-heat cables; 5 is heat transfer sheet; 6 is lagging; 7 is lead; 8 is ventilation duct.
Embodiment:
Technological scheme provided by the present invention is a kind of gasoline air separation, and it can guarantee motor under low temperature environment, proper functioning.Be changed to accompanying-heat cable and heat transfer sheet is an example with companion's hot charging, non-limiting embodiment is as follows.
On the gas and oil separating plant outer wall, wrap with heat transfer sheet 5, twine on it with accompanying-heat cable 4, with bond accompanying-heat cable 4 and heat transfer sheet 5 are fixed as one, with a lead 7 one ends socket on other termination that links to each other with accompanying-heat cable 4, with a lagging 6 with gas and oil separating plant, accompanying-heat cable 4, even backing 5 parcels wherein, heat-resistant cable is between housing 1 and heat-conducting plate 5, and be wound on the housing 1 with screw type or cross type, described heat transfer sheet 5 is covered in housing 1 surface, the heat that accompanying-heat cable 4 is produced is delivered to around gas and oil separating plant and the ventilation duct 8 equably, prevents to freeze in gas and oil separating plant and the ventilation duct.In order to obtain best temperature, described companion is 35cm for the length of cable 4.When the tight hot season, when the engine compartment temperature was high, accompanying-heat cable 4 was because of the decision of its internal semiconductor heating character, and when temperature during greater than 70 ℃, its resistance infinity, thereby temperature has satisfied motor proper functioning under-30 ℃ to 150 ℃ environment not rising.
