A study lead by Tampere University of Technology shows that the usage of pure Neste MY Renewable Diesel in working machines efficiently reduces particulate matter emissions resulting from the use of the fuel. With renewable diesel, both the number of particles as well as particulate mass were reduced in nearly all of the operating cycles of the working machines.
“In this study, the use of renewable diesel in working machines reduced particulate mass by 35 percent on average, and in the best case by nearly 60 percent. Significant reductions of emissions, such as found in this study, have a huge impact on the operator of the machine as well as others in close proximity,” says researcher and Neste’s fuel and engine expert Jukka Nuottimäki who was also one of the researchers in the study.
“The benefits of renewable diesel usage in working machines – such as in street sweepers, excavators and snowplows – are even greater on the average than those resulting from the use in passenger vehicles or trucks. This has to do with the fact that working machines typically lack aftertreatment systems that can already be found in the newest passenger vehicles and trucks,” clarifies postdoctoral researcher Panu Karjalainen from Tampere University of Technology.
About the study and the fuel used
The study measured the local exhaust pipe emissions of working machines from two size categories, operating in an environment simulating real-life working conditions. The tests covered, for example, loading and driving of the working machine both with and without load. The results were derived from a comparison between the use of pure Neste MY Renewable Diesel and conventional fossil diesel meeting European EN 590 diesel fuel standard specifications and consisting of 7 percent of conventional biodiesel, in line with the maximum limit specified by the standard.
The test results will be published as part of a more comprehensive study report in fall 2017. In addition to researchers from Tampere University of Technology, the project involved also researchers and experts from VTT Technical Research Centre of Finland and Neste.
