Abstract
The invention discloses a cold start nozzle in order to solve the problems of difficult starting of an engine in the low-temperature environment. The cold start nozzle comprises a movable core, an electromagnetic coil arranged outside the movable core and a control device, wherein the control device comprises a digital processing chip MCU (micro control unit), a temperature sensor and a triode; an emitter of the triode is connected with the electromagnetic coil, a collector is connected with a power supply, and a base is connected with the digital processing chip MCU; and the temperature sensor is connected with the digital processing chip MCU. The temperature of the engine is detected by the temperature sensor, and the nozzle is controlled by the digital processing chip MCU of an on-board computer to inject oil, so that the air fuel ratio is changed, the cold start and stable operation of the engine in the low-temperature environment are ensured, and the warming-up process of the cold start of the engine is shortened.
Description
Technical field
The present invention relates to a kind of cold start-up nozzle of auxiliary engine cold start-up in low temperature environment.
Background technique
Fuel oil is under the situation that ambient temperature changes, and its volatile performance also respective change can take place, when ambient temperature is low; During as-20 degrees centigrade to 5 degrees centigrade; Because the volatile performance of gasoline is very poor, is not easy to get into tracheae, therefore can not reach the required air fuel ratio of engine operation.Motor is difficult for starting.And owing to the extremely low volatility of gasoline, the mixed gas of formation is rarer in cold start-up and warming-up process for motor, causes engine operation unstable; The fluctuation of speed is also big; Produce a large amount of tail gas simultaneously, so, need a kind of device to realize the cold start-up of motor in low temperature environment; Shorten the warming-up process of engine cold-start, thereby reduce the discharge of harmful gases amount.
Summary of the invention
The object of the present invention is to provide a kind of cold start injector that can solve problem such as engine start difficulty in the low temperature environment.
For realizing that above-mentioned purpose the present invention adopts technological scheme:
A kind of cold start-up nozzle; Comprise movable core, be arranged on the movable core bottom spring, be arranged on movable core upper end the plane valve, be arranged on the outer electromagnetic coil of movable core, be positioned at filler opening, snail type nozzle, the inner chamber of valve top, plane; And control gear; It is characterized in that: said control gear comprises digital processing chip MCU, temperature transducer, triode; Transistor emitter is connected with electromagnetic coil, collector electrode connects power supply, base stage meets digital processing chip MCU, and temperature transducer is connected with digital processing chip MCU.
Said cold start injector is installed on the suction tude, and temperature transducer is contained on the engine body.
Beneficial effect of the present invention:
One, the present invention adopts temperature transducer that engine temperature is detected the digital processing chip MCU control nozzle oil spout of back through vehicle-mounted computer; Change air fuel ratio; Guarantee cold start-up and the ability steady running of motor in low temperature environment, shorten the warming-up process of engine cold-start.
Two, because motor can disposable startup and steady running, disposable startup is compared repeatedly to start and has been reduced the power consumption when successfully starting, and has alleviated the load of storage battery.
Description of drawings
Fig. 1 is circuit of the present invention and structural drawing thereof
Among Fig. 1 Q1 be triode, MCU be vehicle-mounted computer digital processing chip, 1 for movable core, 2 for filler opening, 3 for the plane valve, 4 for electromagnetic coil, 5 for spring, 6 for the snail type nozzle, 7 for temperature transducer, 9 for cold start-up nozzle, 10 for inner chamber.
Embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
A kind of cold start-up nozzle; Be connected with the digital processing chip MCU of temperature transducer and vehicle-mounted computer, it is characterized in that: its composition comprises movable core, be arranged on the spring of movable core bottom, be arranged on the movable core upper end the plane valve, be arranged on the outer electromagnetic coil of movable core, be positioned at filler opening, snail type nozzle, the inner chamber of valve top, plane; Said filler opening links to each other through inner chamber with the snail type nozzle.
Control gear comprises digital processing chip MCU, temperature transducer, triode, and transistor emitter is connected with electromagnetic coil, collector electrode connects power supply, base stage meets digital processing chip MCU, and temperature transducer is connected with digital processing chip MCU.
Said cold start injector is installed on the suction tude, and temperature transducer is contained on the engine body.
The function of cold start injector is when engine low-temperature starting-up, sprays into the additional gasoline of some to suction tude, to add rich mixture.The unlatching of cold start injector and the time of lasting oil spout are depended on the temperature of motor, and by the signal value that ECU returns the temperature transducer back control triode Q1 switch motion of dealing with, thereby the break-make of control electromagnetic coil; When electromagnetic coil is switched on; Electromagnetic coil adhesive movable core is because the plane valve is positioned at the upper end of movable core, so during electromagnetic coil adhesive movable core; Plane valve between filler opening and inner chamber is opened, and fluid is through spraying through the snail type nozzle behind the inner chamber.
