Abstract
The utility model relates to a strong-idling electronic oil economizer, which is composed of a coil, an armature, a coreless valve needle, a spring and a housing body. One end of the coreless valve needle is fixedly connected with the armature installed in a valve core conduit installed in the central hole of a coil bobbin, and a valve body is connected with a solenoid and the housing body. The spring is installed in the solenoid connected with the valve body, and the coreless valve needle is arranged in the solenoid which is connected with the valve body. The utility model has the advantages that the utility model improves the idling stability of an engine, and reduces the idling oil consumption and the CO and CH contents in exhaust emission. The strong-idling condition does not need oil, and the fuel oil of the operating condition is saved. The utility model is also used as a flameout oil stopping valve. When an ignition switch is shut down, the engine can be stopped in time. When a car runs on a downgrade, or on an abrupt slope, or on a long slope, and is in free position to slide and turn corners, and the car is not flameout, the engine is utilized to brake, and the oil can be also saved. Therefore, the utility model improves the running safety of the car, and the installation is convenient. The utility model can be installed on any four-stroke carburetor type engines.
Description
The utility model relates to a kind of strong idling electronic gasoline economizer, a kind of strong idling electronic gasoline economizer with electronic control unit controls solenoid valve that relates to of saying so in more detail.
The fuel economizer of being made up of strong idling solenoid valve and ECU (Electrical Control Unit) is a kind of automobile-used environmental protection and energy saving parts.Be applicable to the strong idle speed control of four-journey carburetor type vehicular engine, the idling fuel feeding of existing Carburetor is to come disposable adjustment by an idle adjusting screw, after adjustment is finished, it is fixing that speed oil is that fuel delivery is, when the anxious deceleration of vehicle (strong idling situation), intake depression can increase to 70～90KQA, and this moment, the discharge concentration of HC sharply increased, and maximum can increase to more than the 10000PPM.According to air fuel ratio and degree of vacuum correlation circumstance, have the partial combustion zone that catches fire, because incoming mixture is diluted burn deterioration by waste gas.Produce this situation, a main cause is because automobile that operating mode speed of a motor vehicle before anxious the deceleration is higher, fuel oil enters suction tude again in the process of cylinder by Carburetor, the part fuel oil remains in around suction tude and the air flue, in case enter under the anxious a certain speed of a motor vehicle of slowing down, remove because degree of vacuum is too high than normal idling degree of vacuum, outside the flow of idling oil system also can increase, part fuel oil on each wall evaporates atomizing simultaneously and has also together sucked in the cylinder on the way, and therefore super dense phenomenon is arranged, simultaneously in the cylinder because the quench effect of casing wall, the fuel oil of atomizing can be cold doubtful on casing wall, diluted the lubricant film of wall, influenced normal lubricating, lower long slope is like this by it.The utility model is a kind of improvement of the prior art.
The purpose of this utility model is: make idling oil tie up to strong idling operation fuel cut-off (this part fuel oil is non-power), improve the idling air fuel ratio, improve toxic emission, improve safety factor of travel, realize the dynamic control of idling oil system according to different operating modes.
The utility model is to constitute like this: it is by coil (5), armature (9), hollow needle (12), spring (10) and housing (7) constitute, one end of hollow needle (12) is fixedly connected on the armature (9), armature (9) is contained in the valve core conduit (8), valve core conduit (8) is contained in the center hole of coil rack (4), valve body connects screwed pipe (11) and connects housing (7), spring (10) is installed in valve body and connects in the screwed pipe (11), hollow needle (12) places valve body to connect screwed pipe (11), porose (13) are offered in the side of hollow needle (12), through hole (14) on hole (13) and the hollow needle (12) connects, through hole (15) is also arranged on the housing (7), make that the cavity (16) in the housing (7) is connected cavity (17) and the connection of the through hole (14) on the hollow needle (12) that screwed pipe (11) forms with valve body, form air passageways.
The utility model has following advantage compared with the prior art:
1, improves engine idle speed stability, reduced CO, CH content in idling oil consumption and the toxic emission.
2, strong idling situation (during anxious the deceleration) not fuel feeding saved the fuel oil of this operating mode, and the CH content in the discharging waste gas is descended significantly.
3, double as the flame-out fuel tap (during engine overheat, because incandescent ignition, idling oil system continues fuel feeding, can not stop) that stops, start function in time to stop when closing ignition switch.
4, at the parking descending, on foot when slope, long slope, flame-out and neutral gear slides and when turning, utilizes engine braking fuel-economizing too, thereby improved vehicle safety.
5, easy for installation, need not the operator has very high technical merit, does not also need original Carburetor is done any changing.
6, Applicable scope is big, can be installed in any four-journey carburetor engine.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model a: end of hollow needle (12) is fixedly connected on the armature (9), armature (9) is contained in the valve core conduit (8), valve core conduit (8) is contained in the center hole of coil rack (4), valve body connects screwed pipe (11) and connects housing (7), Returnning spring (10) is installed in valve body and connects in the screwed pipe (11), hollow needle (12) places valve body to connect screwed pipe (11), the side of hollow needle (12) offers aperture (13), through hole (14) on hole (13) and the hollow needle (12) connects, through hole (15) is also arranged on the housing (7), make that the cavity (16) in the housing (7) is connected cavity (17) and the connection of the through hole (14) on the hollow needle (12) that screwed pipe (11) forms with valve body, form air passageways.
The utility model is to connect screwed pipe (11) by valve body, being installed in the Carburetor idling adjusts on the screw, with the lead of this product with open the ignition switch ato unit after ECU (Electrical Control Unit) (13) is connected, coil (5) energising, adhesive armature (9) and hollow needle (12) make the conducting of idling oil circuit, rotate valve body and adjust engine idle, this system can enter the work of normal idling situation.Consider cover (2) through the valve body air passageways at the idling operation fresh air by screen cloth, by hollow needle (12), enter engine cylinder, dilute gas mixture, CO, CH in idling oil consumption and the discharging waste gas are descended, and another purposes of air passageways is the proper functioning of cooling spool, assurance spool.When motor quickens rotating speed above the setting value in the control unit (16), electromagnetic valve coil (5) outage, armature (9) promotes hollow needle (12) and closes idling oil circuit and air passageways under the effect of Returnning spring (10).When anxious deceleration the (strong idling operation) occurring, carburetor throttle is closed, the interior degree of vacuum of engine air inlet tube this moment sharply increases, because this moment, the idling oil circuit was stopped up by air needle (12), not fuel feeding, saved the fuel oil of this operating mode, make the CH in the waste gas descend more than 90%, when engine speed during near idling speed, ECU (Electrical Control Unit) (16) makes electromagnetic valve coil (5) energising, adhesive armature (9) and hollow needle (12) are opened idling oil circuit and air passageways simultaneously, make motor enter normal idling work.
