<strong>Pierburg</strong> develops AMA 4000 – BMW orders new system generation<br />

Central intelligence, modular design<br />

Neuss/Munich. <strong>Pierburg</strong>’s measurement<br />

technology product group has<br />

ranked among the leading international<br />

suppliers of modern measurement<br />

systems and equipment for many<br />

years. Increasingly stringent requirements<br />

for emission standards in Europe<br />

and the USA have led to a drastic<br />

reduction of pollutant concentrations<br />

in exhaust gas. Measurement experts<br />

at the Neuss-based company have accepted<br />

the challenge and have managed<br />

to secure their hold on the market<br />

for measurement systems. The team<br />

headed by the product group’s manager<br />

Georg Maul has developed a new<br />

generation of exhaust gas measurement<br />

systems (AMA in short) to be<br />

launched under the name of AMA<br />

4000 in March this year. The first order<br />

for the new exhaust gas measurement<br />

system has already been booked from<br />

BMW (Bayerische Motorenwerke <strong>AG</strong>).<br />

In line with legislation in different<br />

countries, the AMA systems can be<br />

used to perform exhaust<br />

gas emission<br />

tests for certificati-<br />

on and to monitor<br />

series production<br />

of vehicles on engine<br />

and chassis dynamometers.<br />

Apart<br />

from systems delivered<br />

to the automobile<br />

industry,<br />

<strong>Pierburg</strong>’s measurement<br />

technology<br />

product group also<br />

supplies custommade<br />

systems to<br />

The advanced,<br />

trend-setting technology<br />

used in the<br />

AMA 2000 analysis unit will also be employed<br />

for the latest generation of exhaust<br />

gas measurement systems. However,<br />

one essential difference is that the<br />

AMA 4000 has a central intelligence<br />

which controls the components via a<br />

bus system. The decentralized structure<br />

(where the individual elements all<br />

had their own computer systems) has<br />

been abandoned in favor of the consistent<br />

use of modular constructions. Jochen<br />

Böning from the sales department<br />

points out that “these modifications<br />

have produced a compact, cost-effective<br />

design. Systems which had to be<br />

accommodated in two AMA cabinets in<br />

the past can now easily be housed in<br />

one”. Sales manager Günter Maassen<br />

adds that “internal communication and<br />

also control of the AMA have changed<br />

decisively as a result of the innovations.”<br />

To achieve a user-friendly and<br />

aesthetic design, the product group<br />

commissioned the Design and Ergonomics<br />

faculty of the University of Essen<br />

to design the cabinet and central control<br />

panel. In the words of Rainer Ballik,<br />

manager of preliminary development<br />

activities: “In designing the AMA<br />

4000, particular consideration was given<br />

to the specific wishes of the customers.<br />

About two years ago, we started<br />

The exhaust gas values of vehicles are tested on a chassis dynamometer. Our<br />

diagram shows the system structure: the vehicle under test is positioned on the<br />

dynamometer. A test driver drives the specified curve, with the system simulating<br />

the resistance exerted on the vehicle when driving along a road. A certain quantity<br />

of exhaust gas is filled into bags during the test and is then analyzed by the AMA.<br />

asking customers what they wanted.<br />

The results of this campaign were then<br />

used to specify the requirements for<br />

the hardware and software of our latest<br />

generation of exhaust gas measurement<br />

systems.”<br />

seeing. The order placed by BMW even<br />

before the AMA 4000 is actually launched<br />

on the market is clear proof of<br />

the quality of the work carried out by<br />

<strong>Pierburg</strong>’s measurement experts. Although<br />

the system will not be available<br />

on the market before March 2000,<br />

BMW has already ordered the AMA<br />

4000 to modernize its exhaust gas<br />

testing centers. <strong>Pierburg</strong> is to install<br />

twelve test facilities in Germany, Austria<br />

and the USA. This is the biggest<br />

single order ever booked by the product<br />

group. And the prospects for the<br />

successful team are good – as an official<br />

World-Wide Selected Supplier of<br />

BMW, the measurement experts will<br />

continue to work as a reliable partner<br />

for the Munich-based car maker in<br />

future, too.<br />

Yet the excellent kick-off for the AMA<br />

4000 with the order from BMW is by no<br />

means the only success story for <strong>Pierburg</strong>’s<br />

measurement technology team.<br />

Other measurement systems have e.g.<br />

been sold to BMW,<br />

Audi, Degussa, Siemens<br />

and Aral.<br />

Measurement facilities<br />

are also being<br />

delivered to Ellring<br />

Klinger, a manufacturer<br />

of engine seals<br />

and sealing systems<br />

in Idstein/<br />

Taunus, to the engine<br />

manufacturer<br />

MAN and to Hatz, a<br />

fan diesel engine developer<br />

in Rurstorf a.<br />

d. Rott near Passau.<br />

Interesting projects<br />

have likewise<br />

been secured<br />

on the international<br />

market:<br />

contracts have, for<br />

instance, been<br />

concluded with<br />

the car maker KIA and the Katech Institute<br />

(Korean Automotive Technology<br />

Institute) in Korea. In addition,<br />

complete measurement systems have<br />

been ordered by India – where a<br />

major order was placed by the company<br />

Mico – and China despite harsh<br />

competition there.
