3. Description
3.1 Introduction
The Type 2516B… is a handy peak-pressure measuring
instrument for measuring the cylinder pressure of internal
combustion engines with a speed range of up to 4 000
1/min.
This battery-operated measuring instrument measures
between 1 … 100 pressure cycles, from which it
calculates the arithmetic mean value of the peak
pressure, standard deviation, steepest slope of the
pressure curve as well as the average pressure curve.
The numerical data are shown on the LC display and can
be saved as required. The average pressure curve can
be analyzed with the software contained in the included
accessories.
An additional measuring function allows the peak
pressure ("Peak") to be displayed without limitation of
time. The analog sensor signal always appears at the
monitor output.
3.2 Measuring functions
1. Statistical evaluation of 1 ... 100 pressure cycles
pmax maximum peak pressure
pmin minimum peak pressure
pav average peak pressure
psdev Standard deviation of the peak pressure
(dp/dca) max steepest slope of the pressure curve
Speed speed
2. Pressure curve (p-t)
Average pressure curve with a resolution of 720
measuring points per revolution, which can be printed
out via the USB interface (ASCII file). The pressure
curve can be displayed with the software provided.
Please note that the pressure curve has not been
recorded in relation to the crank angle. The scaling of
the x-axis in °crank angle has been selected only for
the purpose of providing a better illustration, where
360 measuring points represent 360 °KW. For a first
expertise the pressure curve can be displayed on the
display.
Description
2516B1_002-888e-10.19 Page 7
3. Instantaneous peak value "Peak"
The peak pressure is shown without limit of time. For
this application, we recommend use of the optionally
available plug-in power unit Art. No. 5.510.293.
4. Average value of the stored pav values.
The average value is calculated from the measurands
stored in Memory Block 1 pav and shown on the
display. For the purpose of calculating this value, it is
essential to store the measurements in ascending
sequence (Store to Memory 1 –> 20). If this is not
done, the error message "Error" will appear for the pav
value, while all other measurands will be shown
correctly.
3.3 Functional principle
The cylinder pressure is measured with a pressure
sensor such as Type 7613C… at the indicator valve of
the engine. Since long indicator tubes cause pipe
oscillations, which can falsify the measuring signal, the
cylinder pressure signal can be smoothed with an
adjustable low-pass filter. The rechargeable battery has a
operating time of about 4 hours. If the symbol
appears on the LCD display, the battery must be

recharged. The meter will switch off automatically 2
minutes after the last button actuation, provided this
function has not been deactivated (see chapter 4.2 Start-
up).
The Engine Peak Meter has ä-conformity according to
EC Directive 89/336/EEC and complies with EMC
standards for industrial and laboratory equipment
(interference emission EN 61000-6-3 and 4 respectively
as well as interference immunity EN 61000-6-2 and 1
respectively).
Description
2516B1_002-888e-10.19 Page 9
3.4 Measuring process
3.4.1 Zero shifter
The meter has a special Zero Shifter function, which
automatically sets the various quiescent voltages of the
connected sensors to a specific value = zero point. The
display will show "Wait" until this value is reached upon
which the display will show "Ready" and the meter will
then be ready to operate. If the "Measure" button is
pressed during "Wait", the measuring process will not
start. The button is operational only when "Ready"
appears.
After successful actuation of the measuring process, the
meter waits until the set trigger threshold of the pressure
signal is reached before it analyzes the selected number
of operating cycles.
Fig. 2: Measuring principle
The "Measure" button has been pressed before
the time t = 0, i.e. at time t = 0 the meter is
already synchronized with the engine speed.
Engine Peak Meter Type 2516B1/B12
Page 10 2516B1_002-888e-10.19
3.4.2 The measurement
After the "Measure" button has been pressed, a check is
made as to whether a pressure signal exists and whether
the trigger threshold has been reached. If this is the case,
the meter synchronizes with the engine, then determines
the period and from it the engine speed, and analyzes a
given number of combustion cycles according to the
settings selected in the menu.
Every second pressure curve is acquired for the
evaluation. The measurement is started by means of a
pre-trigger in the low pressure range (charge-air
pressure).
With a four-stroke engine, only the compression and
combustion strokes are recorded (first 360 ° of the
combustion cycle).
