Fill level

Oil level and oil quality are detected on the basis of the capacitance

of the engine oil (dielectric). The oil temperature is detected by the

temperature sensor. All the signals are processed in the electronics

to form a PWM signal and transferred to the engine control unit.

The measuring principle of the oil sensor is a capacitance

measurement, whereby the capacitance is dependent upon the oil

level. The measuring system consists of two cylinder condensers

which possess a metal pipe as a common external electrode. Both

other electrodes are arranged over each other as an inner pipe.

The dielectric constant of the engine oil is determined by the lower
condenser (C
2
) which is always full of oil (

e
approximately 2.3 to 4.0).
The fill level (h) is then determined by the upper condenser (C

1
)

using the dielectric constant. The capacitance of the upper

condenser (C
1
) is calculated on the basis of a parallel connection
with two condensers which have air and engine oil as a dielectric

material.

The condensers are located in a plastic housing which serves as a

damping cup. The engine oil flows through the feed bore holes into

the housing between the condensers.

The measuring range for the oil level is 80 mm

(normal level

F
40 mm), accuracy of measurement approx.

F
3 mm.

The voltage for the oil sensor (approx. 5 V) is supplied by the engine

control unit.

Each information block consists of three successive square-wave

signals, This is followed by a short pause.

A measured variable is assigned to each square-wave signal (A, B,

C). The quantisizing in each case is based on the on/off ratio (T) of
approx. 20 to 80 %.

Because oil level and oil quality (capacitance of the engine oil) are

dependent of each other, this information is first compensated for in

the engine control unit, before it is transmitted via CAN databus to

instrument cluster.

The following faults at the oil sensor are detected by the engine

control unit and entered in the fault memory:

- Duty cycle of a signal less than 17 % or more than 83 %

- Dielectric constant of engine oil longer than 100 seconds greater

than 5.8 (e.g. because of a lot of water in the engine oil).
