Program14th Int. AVL Symposium on Propulsion DiagnosticsJune 23-24, 2020, Kurhaus Baden-Baden, Germany

INTRODUCTION

The lucky number 13 was the start of the Propulsion Diag-

nostics Symposium in 2018, with which we - recognizing the

signs of the times - successfully extended the topic of metro-

logical challenges from combustion in combustion engines

to the entire powertrain. The 14th International AVL Pro-

pulsion Diagnostics Symposium is scheduled for June 2020.

„What has changed recently? Have our industry’s priorities

shifted?“ These are questions that concern us all. We can

see that the development activities around the electrified

powertrain have been intensified. This applies both to

all-electric drives and hybrid powertrains. That said, the

prevalence of hybrids ensures the continuous importance of

the combustion engine as a propulsion source in the coming

years; so that development will continue here as well.

In addition to the technical issues relating to the new pow-

ertrains, we must not ignore the infrastructure. Customers

want to know how quickly and comfortably they can „refuel“

with electricity, for example, or where the nearest hydrogen

filling station is located.

But what do these changes mean for our Propulsion

Diagnostics Symposium? Does everything have to be

optimized at the same time?

In the past, only combustion was measured, analyzed and

improved; today, the effects on noise and emissions must be

addressed at the same time. Does it make sense to optimize

the electric propulsion system at the same time as the com-

bustion engine? Has the importance of time as a factor in

development increased further? What effects does this have

on measurement technology?

To limit the breadth of these many questions somewhat, we

have agreed on a number of current topics in the Program

Advisory Board, which give us the opportunity to discuss

these topics on the basis of technical questions:

• Electrified Powertrain

• Hydrogen / Fuel Cell

• Emissions – Generation and Avoidance

• Noise, Vibration & Harshness

• Combustion Diagnostics

• Visualization / Simulation of Dynamic Processes

• Onboard Monitoring and Diagnostics

At this symposium, we are providing an ideal platform with

lectures and an intensive dialogue between experts and

users to discuss these burning issues and promote the trans-

fer of knowledge. We would like to present not only excel-

lent technical solutions on a modern powertrain, but also the

metrological challenges. The focus will be on the „why and

how“ in the developments.

The efficiency of the gasoline engine, for example, is to

be massively increased and this will become possible if its

operating range is changed by a suitable electric motor

application. Or in the inverter, the switching frequency is

constantly increased to achieve higher efficiencies of the

electric propulsion. Many of these changes in the powertrain

lead to additional measurement requirements that must be

met to understand details. Only then can the overall system

be optimized - usually supported by simulation - since the

interactions between mature individual components can be

understood and evaluated.

The conference addresses not only combustion developers

of all engine sizes, but also transmission, electric motor,

inverter, battery, mechanics developers and calibration

engineers.

You can look forward to exciting lectures, good discussions

and an intensive professional exchange. We look forward to

seeing you there.

On behalf of the entire Program Advisory Board
