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).

To display the temperature, the

requires:

D
the outside temperature

D
the speed signal

D
the engine running time

and
D
the coolant temperature (model 129, and model 140 as of
1.6.96, model 170, model 202 as of 08/96 and model 163,

The outside temperature is determined by the outside temperature

indicator temperature sensor B14. The temperature sensor is

installed at the front left of the vehicle under the bumper and

connected to the instrument cluster A1 via the 21 or 25-pin

connector, coding part A terminal 1 and 2.

The speed signal, engine running time and engine temperature are

determined internally by the instrument cluster A1.

Since the outside temperature display depends on the speed, engine

running time and coolant temperature, high temperatures (influenced

by the heat generated by the engine, for example) are not displayed

when the vehicle is stationary or moving slowly.
Function, model 202 until 08/95

When the ignition is switched on and off and at speeds below approx.

20 km/h, the last temperature measured is stored and displayed.

If the measured outside temperature drops below the stored value,

the current measured temperature is displayed.

If the outside temperature rises above the stored value, the current

measured outside temperature is displayed only after the following

delays:

D
When the engine is not running, the current outside

temperature is only displayed after 6 times the engine running

time. For example, if the preceding running time was 5 minutes,

the current temperature is not displayed until after 30 minutes.
The maximum delay, however, is 1 hour.

Piezo-electric effect:

A thin quartz plate (c) is coated on two opposing sides with a conductive material (a), (b) (see

illustration). If a tensile or compressive load is applied to the array, an electrical voltage "U" i
s

produced between the points (d) and (e). The polarity of the generated voltage depends on the

direction of load (compression/tension).

Reversed piezo-electric effect:

If, however, a voltage is applied to the points (d) and (e), the quartz plate increases or decreases


in length.

Task:

Mechanical vibrations can be converted into electrical oscillations using the piezo-electric effect.


For example, for microphones, knock sensors, pressure sensors.

Electrical oscillations can be converted into mechanical vibrations or motion using the reversed

piezo-electric effect: piezo-electric speakers, actuators.

Both effects are combined in the quartz resonator: If an AC voltage whose frequency is roughly

equal to the mechanical resonant frequency (fundamental or harmonic component) of the quartz

plate is applied to the points (d) and (e), the quartz is stimulated to generate resonant vibrations


which stabilize the frequency of the electrical oscillations. For this reason, quartz resonators are


often used where a high degree of frequency stability is required (e.g. in clock generators

(oscillators) for electronic clocks and microprocessors).
