Further improvement of air purity

Over and above the effects of the production programme, emissions of dust, carbon dioxide, benzene and nitrogen oxide have decreased substantially as a result of particularly low-emission engines being tested and a shortening of the testing times in the test bay.

DEUTZ Group: Emissions per engine in our plants 1)    
  2015 2014
Emissions per engine    
CO2 (kg) 460 365
Nitrogen oxide (kg) 0.128 0.140
Dust (g) 2.6 2.7
Benzene (mg) 44.8 48.6
1) CO2 emissions in plants in the DEUTZ Group. All other figures relate to German plants.

A variety of individual technical and organisational measures made it possible to shorten the testing times. To further reduce emissions and costs, we are planning to carry out cold testing 2) of some of our products in the production test bays in Cologne. The construction of a laboratory for exhaust aftertreatment technology, which contains a model gas testing rig, enables the simulation of engine emissions for bench-scale testing. This saves on various test runs at the development stage.

In order to satisfy customers’ requirement for even more eco-friendly engine technologies, DEUTZ AG has converted four of its test cells so that engines can be tested with LPG as part of research and development. The advantage in terms of air purity is obvious: LPG-powered engines do not emit any dust.
