Background technique
Crankcase ventilation system is one of important constituent element of motor, and its major function is reasonably to control crankcase pressure; Oil gas in the crankcase emissions is separated, and the machine oil after will separating is simultaneously got back to oil sump.Owing to containing a large amount of moisture content in the crank case gases, at the vehicle of Han Qu work crankcase ventilation system often can appear because icing resulting in blockage caused sealing place seepage machine oil, and finally cause motor to be scrapped.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of vehicle crankcase ventilation system of can avoiding and freezes, and guarantees the crankcase ventilation heating system of the reliability when vehicle uses in extremely cold area.
Crankcase ventilation heating system of the present invention comprises the hot-air heater that ventilates to, controller, temperature transducer, the first relay; The described hot-air heater that ventilates to is fixed between the air induction hose and steam outlet pipe of crankcase, and temperature transducer is fixed on the vehicle body; Temperature transducer is converted to the ambient temperature of measuring electrical signal and it is transferred to controller, controller judges according to this electrical signal whether ambient temperature is lower than crankcase normal working temperature lower limit, if be lower than crankcase normal working temperature lower limit, then export control signal and connect the first relay, the hot-air heater that ventilates to is started working.
The present invention utilizes the temperature sensor measurement ambient temperature, when being lower than under the crankcase ventilation system normal working temperature, ambient temperature prescribes a time limit, connect the first relay by controller output control signal, the hot-air heater that ventilates to is started working, the air that enters crankcase and the air of getting rid of crankcase are heated, solve the cold district of engine crankshaft ventilation system ice formation issues, guaranteed the reliability when vehicle uses in extremely cold area.The present invention is simple in structure, is convenient to complete machine and arranges.
The present invention can also comprise deaerator heater and the second relay; The deaerator heater is fixed on the deaerator of crankcase; If the ambient temperature that temperature transducer records is lower than crankcase ventilation system normal working temperature lower limit, then controller output control signal is connected the second relay the deaerator heater is started working.
Prescribe a time limit when ambient temperature is lower than under the crankcase ventilation system normal working temperature, the present invention utilizes the deaerator heater that deaerator is heated, and has further guaranteed the reliability when vehicle uses in extremely cold area.
The present invention can also comprise velocity transducer; Described velocity transducer is installed on the engine output shaft, controller judges according to the signal of velocity transducer output whether motor is in normal working, if motor is in normal working, and the ambient temperature that temperature transducer records is lower than crankcase ventilation system normal working temperature lower limit, then export control signal and connect the first relay the hot-air heater that ventilates to is started working, export perhaps that control signal is connected the first relay simultaneously, the second relay is started working the hot-air heater that ventilates to, deaerator heater simultaneously.
According to test result, there is not ice formation issues in the ventilation of engine start Front crank case, therefore, do not need heater work before startup and in the start-up course.Therefore, for the ease of conserve energy, and in the engine cold-start process, do not increase the generator burden, guarantee that car load can start smoothly, the present invention utilizes velocity transducer to measure engine behavior, when motor is in normal working, and ambient temperature is lower than crankcase normal working temperature lower limit, by controller output control signal the hot-air heater that ventilates to, deaerator heater are started working, ventilation system is heated, to guarantee the reliability of vehicle when extremely trembling with fear the area use.
Described controller can also compare voltage signal and the predefined value of generator output, if less than predefined value, and ambient temperature is lower than crankcase ventilation system normal working temperature lower limit, motor is in normal working simultaneously, then export control signal and connect the first relay the hot-air heater that ventilates to is started working, export perhaps that control signal is connected the first relay simultaneously, the second relay is started working the hot-air heater that ventilates to, deaerator heater simultaneously.
If generator output voltage is lower than predefined value, whole electrical system existing problems are described, at this moment, car load can't work, and the crankcase ventilation heating system does not need work equally.Therefore, the present invention utilizes controller to judge whether generator output voltage is lower than predefined value; Do not work if be lower than predefined value then ventilate to hot-air heater, deaerator heater, be convenient to conserve energy.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is crankcase ventilation heating system scheme of installation of the present invention.
Fig. 2 is crankcase ventilation heating system principle schematic of the present invention.
Fig. 3 is the controller software flow chart.
Embodiment
As shown in Figure 1, crankcase ventilation heating system of the present invention is comprised of the hot-air heater 1 that ventilates to, deaerator heater 2, temperature transducer 8, velocity transducer 9, the first relay 10, the second relay 11 and controller 4.Described controller can adopt the CPU of vehicle-mounted computer ECU inside, also can adopt other microprocessors.The hot-air heater 1 that ventilates to is fixed between the air induction hose 5 and steam outlet pipe 6 of crankcase by clip, and deaerator heater 2 is fixed on the crankcase oils gas separating device 7 by clip.The hot-air heater 1 that ventilates to is connected with controller 4 by heating wire harness 12, the first relay 10; Deaerator heater 2 is connected with controller 4 by heating wire harness 13, the second relay 11.Temperature transducer 8 is installed on the vehicle body.Velocity transducer 9 is photoelectric encoder, is installed on the engine output shaft.Temperature transducer 8, velocity transducer 9, crankcase generator power supply are connected with controller 4 respectively.
