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).
