Testing Trends

Poppe +Potthoff Maschinenbau in an interview with “Automotive Testing Technology International”

Werther/Nordhausen (Germany), May 19, 2016 - In an interview with “Automotive Testing Technology International”, Frank Baudler, CTO at Poppe + Potthoff Maschinenbau, discusses the need for more stringent testing of plastic and lightweight components found in engines.

What are the current trends in powertrain development?

The need for clean and efficient combustion is increasing. This is mainly achieved by raising the pressure of the injection system, which places high demands on the components used. We have seen this in the development of diesel engines. Now, this trend is additionally being fueled by engines using gasoline and mixtures with bio-fuels.

What challenges does this present?

Where the pressure – and therefore the heat – is on the rise, vehicle developers need to consider the impact of gasoline and bio-fuels on the components and systems that are made of metal or plastic. They must also ensure that the compressive strength and temperature stability is sufficient under oscillating and continuous stress, and that the gas tightness is assured even after thousands of utilization cycles. We believe that in future we will see an even stronger need to test plastic and lightweight components under pressure. More automated quality approval is also a focus for the industry.

How is P+P developing its technology to meet these challenges?

P+P can offer a full range of high pressure testing technology for gasoline and diesel applications as well as gas fuelled systems and pumps. Our test stands achieve up to 6,000 bar impulses at up to 30Hz, for example. Meanwhile, our current machine for gasoline injection systems tests with up to 2,000 bar at a frequency of up to 2Hz and 10Hz.

Poppe + Potthoff Maschinenbau will be at stand 1104 at Automotive Testing Expo Europe 2016, which takes place on May 31-June 2 in Stuttgart, Germany.  The experts for high pressure technology will also be exhibiting at the Automotive Testing Expo in China (booth 6048, September 27-29, 2016) and North America (booth 1101/1102, together with R+W Coupling Technology, October 25-27, 2016).
