Motor is in severe cold winter starting difficulty, and this is because engine oil viscosity increases, and resistance of start square increases, and battery-operated ability reduces, and the cause of gasification of fuel oil performance depreciation.For making it to be convenient to start, should manage air inlet, lubricant oil and cooling water preheating in the winter time.Diesel engine winter difficulty in starting is especially large.Diesel engine for automobile, in order to start reliably rapidly at low temperatures, often adopts some in order to the startup auxiliary device improving fuel fire condition and reduce detent torque, as glow plug, intake air preheater, primer fluid injection apparatus and decompressor etc.
Because temperature is low, the rate of gasification of vehicle fuel declines, lean out and nonflammablely cause difficulty in starting.In addition, the chemical reaction of battery liquid is slow, causes the electricity deficiency, Starter underpower and the ignition voltage that export during startup not enough, makes motor be difficult to start.Therefore, in the season of cold, common method first should carry out preheating to motor before automobile starting.Hot water or steam can be poured in radiator and water jacket, utilize temperature conduction in water jacket to cylinder wall, make the fuel oil entered in cylinder during startup be easy to gasification, and the temperature of inflammable mixture can be improved, with convenient burning.Also preheating be can carry out to strengthen the electricity of storage battery to storage battery as required, inrush current and ignition voltage improved.
But current automobile normally cannot start principal phenomena under low-temperature condition: the combustion gas needed during engine combustion does not enter that engine agitator, supply gas pressure are too small, engine electromagnet valve is not opened, and therefore governs engine cold-starting.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of temperature control, facilitate the motor car engine low-temperature startup device of engine cold-starting.
In order to solve the problems of the technologies described above, the invention provides a kind of motor car engine low-temperature startup device, comprise intake manifold, described intake manifold is connected with bypass branch, described bypass branch is connected with air-regulating valve, and described air-regulating valve comprises bimetallic strip, electric heating coil and air lock, and described electric heating coil one end connects bimetallic strip, one end connects wiring base in addition, and the other one end of described bimetallic strip connects air lock; Described intake manifold is also disposed with gasifying tank and knock out drum, is provided with heating tube in described gasifying tank, described heating tube one end connects into hot-water line, and one end connects outlet pipe in addition; In described intake manifold, be also provided with moral door room, described solar term room arranges closure and bypass air flue, and the intake manifold of described closure and bypass air flue joint also arranges throttle adjust screw.
The motor car engine low-temperature startup device tool of technique scheme is adopted to have the following advantages: when motor starts at low temperatures, air lock is in opening state, air can enter into firing chamber through the air-regulating valve of bypass branch, after engine start, electric current can flow through electric heating coil and heat bimetallic strip, like this, bimetal sector-meeting heated bending, gradually air lock cuts out, air-regulating valve contributes to engine cold-starting in bypass branch, after warming-up, the air lock of air-regulating valve is buttoned-up status, in addition, during engine idle, closure is closed completely, air can flow through bypass air flue, now adjust throttle adjust screw alterable idling speed, when engine speed raises, closure is opened gradually, air flows through intake manifold, therefore, by controlling the air demand of closure room to the fuel oil room of motor, thus the rotating speed of adjustable motor, contribute to cold-starting, simultaneously, intake manifold is also disposed with gasifying tank and knock out drum, gasifying tank passes through in heating tube, pass into hot water into hot-water line, hot water in heating tube is to the air heating in gasifying tank, make it gasification, flow out through outlet pipe adding in underwater pipeline stabilizing the water after turning cold after to gasifying tank heating, thus play control temperature, facilitate the effect of engine cold-starting.
Preferably, in order to control the switch of air lock flexibly, described air lock connects return spring, and the other one end of return spring is fixed on air-regulating valve.
Preferably, conveniently control the air mass flow in intake manifold, described intake manifold arranges flow control valve.
Preferably, consider the convenient temperature controlling air in gasifying tank, add set temperature control valve on gasifying tank described.
