Abstract
The invention relates to an electric control exhaust diesel filter used in a diesel motor vehicle. The electric control exhaust diesel filter is provided with a shell, a filter element is arranged in the shell, and an oil inlet and an oil outlet are arranged at the top of the shell. The electric control exhaust diesel filter is characterized in that an oil storage and exhaust tank is mounted above the shell, an oil inlet and an oil outlet are arranged at the bottom of the oil storage and exhaust tank, an exhaust tube is disposed at the top of the oil storage and exhaust tank, and the oil inlet on the oil storage and exhaust tank is abutted to an oil outlet on the shell; and an upper liquid level sensor and a lower liquid level sensor are mounted in the oil storage and exhaust tank, an electromagnetic valve is mounted in the exhaust tube, the upper liquid level sensor is connected with the electromagnetic valve in a control manner, and the lower liquid level sensor is connected with an engine choke in a control manner. The electric control exhaust diesel filter resolves problems that a common diesel oil filter cannot exhaust air, operation of an engine is affected, however, a brand-new automatic air exhausting diesel oil filter is complex in structure and difficult in manufacture, particularly, the engine can be easily shut down gradually due to the brand-new automatic air exhausting diesel oil filter, and can shake abnormally to be damaged, and the like. The electric control exhaust diesel filter is suitable for diesel supply systems of various diesel motor vehicles.
Description
(1). technical field: the present invention relates to the motor vehicle component, especially a kind of automatically controlled exhaust diesel-oil filter.
(2). background technique: the diesel engine fuel-firing supply system is divided low-voltage fuel fuel feeding and two parts of high pressure fuel fuel feeding; All air can not be arranged in motor whens operation two cover oil circuits, in the oil circuit in case have air to get into the high pressure oil pump motor just can not normally to move even stop working.High pressure oil pump exhaust operation is very complicated, and particularly the electric-control diesel engine high pressure oil pump more can not advance air.Existing common diesel-oil filter is the air that can not get rid of in the oil circuit, has therefore had a strong impact on the work of motor.The inventor has successively invented " diesel filter for automatically removing air " and " diesel engine is used deaerator " and has all applied for national inventing patent in 2009 and 2011; The former is Grant Patent Right for Invention; These two kinds of filter cleaners can both separate the air in the low pressure oil circuit, guarantee that air can not get into high pressure oil pump.When the air in the low pressure oil circuit was about to get into high pressure oil pump, the float oil cut-off valve cut out the passage between low pressure oil circuit and the high pressure oil pump automatically, and the low pressure oil circuit stops to the high pressure oil pump fuel feeding gradually.The high pressure oil pump plunger upper part produces vacuum and can not pump oil, and motor is slowly flame-out, and it is flame-out that so flame-out mode belongs to the non-normal flameout pattern, and motor is shaken terribly, and motor is had damage, and is also unfavorable to high pressure oil pump.
(3). summary of the invention: the object of the invention is exactly two oil purifier fuel cut-off gradually when low pressure oil circuit oil starvation that will solve previous invention; Make motor slowly flame-out; Cause the motor shake severe easily; Motor is brought damage, and, a kind of automatically controlled exhaust diesel-oil filter is provided problem such as high pressure oil pump is unfavorable.
Concrete scheme of the present invention is: a kind of automatically controlled exhaust diesel-oil filter; Have housing, filter core is housed in the housing, the top of housing is provided with filler opening and oil outlet; It is characterized in that: the oil storage exhaust box is housed above housing; Oil storage exhaust box bottom is provided with oil-feed and oil outlet, and the top is provided with outlet pipe, and the filler opening on the oil storage exhaust box docks with oil outlet on the housing; Two liquid level sensors up and down are housed in the oil storage exhaust box, in described outlet pipe, solenoid valve are housed, the said liquid level sensor control connection solenoid valve of going up, said liquid level sensor down, control connection engine misses device.
Oil storage exhaust box fuel oil is not revealed during cleaned and changed for ease filter core, and one-way valve is equipped with at the filler opening place at the oil storage exhaust box among the present invention.
During for the automatically removing air operation, its pressure is lower than oil return pressure regulator valve pressure, keeps the low pressure oil circuit to have certain pressure, and pressure regulator valve is housed in outlet pipe among the present invention.
Working principle of the present invention is:
1. during low pressure oil circuit normal fuel injection, diesel oil gets into filter element filtering by filler opening after the oil transfer pump pressurization; Get into the oil storage exhaust box through one-way valve, solenoid valve is in closed condition, and the oil storage exhaust box forms confined space; To the high pressure oil pump fuel feeding, motor normally moves fuel oil through oil outlet;
2. during low pressure oil circuit infiltrated air, fuel oil and air together get into the oil storage exhaust box, because air is lighter than diesel oil, accumulate in oil storage exhaust box top, fuel oil through oil outlet to the high pressure oil pump oil transportation.Along with increasing of air, oily plane drops to goes up the liquid level sensor position, and sensor starts, solenoid valve; Solenoid valve is opened, and air backs down pressure regulator valve, discharges through outlet pipe; To high-pressure service pump still fuel feeding, but oil pressure is lower than normal oil pressure to fuel oil through oil outlet, and motor gets into the limping mode of operation.Along with the discharge of air, oily plane rises to more than the liquid level sensor position, and sensor stops to solenoid valve, the closed electromagnetic valve outlet pipe, and the oil storage exhaust box forms seal space again, and oil outlet recovers normal fuel injection again, and motor normally moves.Along with the increase of air gets into next circulating exhaust and fuel feeding work again.Though low pressure oil circuit infiltrated air has had this equipment motor still can be to walk lamely and the normal mode alternate run;
3. when the low pressure oil circuit did not have supplying fuel, motor is short time work still, and air constantly gets into the oil storage exhaust box; The oil plane drops to liquid level and passes the device position; Last liquid level sensor is to solenoid valve, and solenoid valve is opened outlet pipe, and following liquid sensor is then in time controlled engine misses; Air just can not get into high pressure oil pump through oil outlet behind the engine misses, has protected high pressure oil pump to get into next round work with normal condition.Just need not worry the high pressure oil pump part when carrying out the exhaust operation,, need not tear other positions open when getting rid of low pressure oil circuit air, make exhaust work very simple because outlet pipe is opened automatically.Because outlet pipe communicates with fuel tank through return tube, oily foam flows in the fuel tank, has not a particle of fuel oil and leaks, fuel oil waste when having stopped the exhaust operation.
The present invention is simple in structure, and reliable operation can effectively be got rid of the air in the oil circuit, guarantees the efficient stable work of motor, and is in time flame-out fast when low pressure oil circuit oil starvation, avoids motor shake and damage, helps protecting high pressure oil pump simultaneously.
