Abstract
The utility model discloses a sensor for integrally measuring engine oil liquid level and crankcase pressure. The sensor adopts the structure that an oil level sensor and an oil pressure sensor are sleeved outside an oil dipstick; signal wires of the two sensors are led out from a sealing port at the upper part of the oil dipstick; and the oil dipstick is hermetically fixed with a crankcase through a fastener 5. The sensor has a simple structure and is extremely easy to assemble or disassemble. The sensor is arranged on the crankcase of a machine body; and the bottom of the oil level sensor stretches below the normal liquid level. The sensor is placed in the space of the oil dipstick of the common engine, so that the sensor can monitor the liquid level of the engine oil of the engine and the pressure of the crankcase all the time.
Description
Technical field
The utility model belongs to internal combustion engine part, is specifically related to the sensor of a kind of detection of engine oil sump oil level simultaneously and crankcase pressure.
Background technique
As everyone knows, all movement parts of motor all need oil lubricating, and understand some loss in the motor course of normal operation.For example: ooze out the motor outside from the sealing position; With the exhaust gas leakage of resuscitation apparatus to external environment; Other has part machine oil entering firing chamber to be burnt.The main cause of oil impregnate is except the Sealing problem, and main cause is exactly the overpressure of crankcase.It is extremely important to the monitoring of crankcase pressure and Oil Level in the motor using process that hence one can see that.And the monitoring of crankcase pressure at present is to obtain through the pressure transducer that is installed on the resuscitation apparatus; The detection of engine sump tank Oil Level relies on dipstick.Obviously, use dipstick to detect outside the inconvenience, can not carry out accurate Calculation certain hour or hundred kilometers machine oil damage consumptions.The proposition of the utility model can make the problems referred to above obtain satisfied the solution.
Summary of the invention
The objective of the invention is, the sensor of a kind of detection of engine oil sump oil level simultaneously and crankcase pressure is provided.
Describe below in conjunction with the principle and the structure of accompanying drawing the utility model.
Collection engine oil level and crankcase pressure one measured sensor are set with fuel level sensor and oil pressure sensor in the outside of dipstick, the signaling line of two sensors is drawn from dipstick top seal mouth.Dipstick is fixed through fastening piece and crankcase seals.
Dipstick is put into crankcase, and this moment, fuel level sensor was positioned at oil 60mm (standard machine oil volume) down.When the too much oil level of consumption of lubricating oil reduced, fuel level sensor was with outgoing signal, and the machine oil volume ratio reference value of demonstration reduces.Pressure transducer is positioned at crankcase inside, is positioned at simultaneously more than the machine oil liquid level.Above-mentioned two kinds of sensors are integrated dexterously, and liquid level and crankcase pressure are accurately monitored simultaneously.And when engine sump tank machine oil reduces, can carry out quantitative analysis to the reason of its minimizing.
The characteristics of the utility model are that simple in structure, very easily installation or removal are put into this device in the spatial position of common engine dipstick, can monitor constantly engine motor oil liquid level position and crankcase pressure.
Description of drawings
Shown in accompanying drawing be the structure and the principle sketch of the utility model.
Specific embodiment
Below in conjunction with accompanying drawing and through embodiment the principle and the structure of the utility model are done further explanation.
Collection engine oil level and crankcase pressure one measured sensor, its structure are that the signaling line that is set with fuel level sensor 2 and 3, two sensors of oil pressure sensor in the outside of dipstick 1 is drawn from dipstick top seal mouth 4.Dipstick 1 is fixed through fastening piece 5 and crankcase seals.
This device is installed on the body crankcase, and fuel level sensor bottom is goed deep into below the normal level of liquid, the pressure of oil sump liquid level and crankcase is carried out data simultaneously read.
The utility model is through comparative trial test: (1) with this device be installed on the bigger fault model machine of motor air leakage with a normal motor on, respectively its crankcase pressure is detected, measure the size differences of both pressure.(2) this device is installed in a resuscitation apparatus and drips on the motor of machine oil, carry out oil consumption test in 24 hours, before the test machine oil that drips in the resuscitation apparatus is collected, so that the data that read are confirmed.
Test result:
(1) 4102 h type engine h air leakage, crankcase pressure test detect:
| ? | Air leakage testing result (L/min) | Crankcase pressure testing result (KPa) |
| Normal motor | 62 | ?0.43 |
| The motor that air leakage is big | 86 | ?1.13 |
(2) 4102 h type engine h resuscitation apparatuss drip the bit test of machine oil engine liquid and detect:
| Duration of test oil consumption (kg) | 4.2 |
| The oil level that the resuscitation apparatus of collecting oozes (kg) | 4.6 |
Can find out that through detecting data this device can accurately detect the variation of different crankcase pressures and crankcase inner engine oil liquid level.
Claims (2)
1. collection engine oil level and crankcase pressure one measured sensor is characterized in that being set with fuel level sensor (2) and oil pressure sensor (3) in the outside of dipstick (1), and the signaling line of two sensors is drawn from dipstick top seal mouth (4).
2. according to described collection engine oil level of claim 1 and crankcase pressure one measured sensor, it is characterized in that said dipstick (1) fixes through fastening piece (5) and crankcase seals.
