A novel method for automated SCR catalyst uniformity measurement

Autor: Mauri Haataja, Satu Pitkäaho, Tiina Pääkkönen, Esa Väisänen, Sauli Halonen

Exhaust after treatment systems are becoming more complicated with the ever-stricter emission regulations. To meet the regulation limits, a tightly packed high-performance system is required. In selective catalytic reduction (SCR) systems, ammonia (N

Benchmarking of two flexible multibody dynamic simulation software in engine simulations

Autor: Tero Frondelius, Antti Mäntylä, Ilkka Väisänen, Teemu Kuivaniemi, Terho Tuohineva, Mauri Haataja

Publikováno v: Rakenteiden Mekaniikka

In this paper, two different commercial multibody dynamic (MBD) simulation software cases are studied. Due to the restrictions determined in the conditions of contract, the names of the software are not revealed, instead being called Software S and S

Use of a snow cannon to test effect of different coatings for adhesion of snow in railway applications

Autor: Jarno Junnikkala, Karoliina Jokinen, Jonne Untinen, Mauri Haataja

Publikováno v: Advances in Mechanism and Machine Science ISBN: 9783030201302

This paper describes implementation of a snow cannon for testing different coatings for adhesion of snow in railway applications. A spray of snow is targeted to a test plate and the accumulated mass of snow is measured. The test plate can be coated w

Urea-Water-Solution Properties: Density, Viscosity, and Surface Tension in an Under-Saturated Solution

Autor: Mauri Haataja, Sauli Halonen, Ulla Lassi, Teija Kangas

Publikováno v: Emission Control Science and Technology. 3:161-170

A temperature-concentration dependent surface fit for the relative viscosity of a urea-water-solution (UWS) is calculated based on experimental and literature data. For the surface fit, a 2D Lorentzian function was used, where the x-axis was assigned

History of structural analysis & dynamics of Wärtsilä medium speed engines

Autor: Tero Frondelius, Hannu Tienhaara, Mauri Haataja

Publikováno v: Rakenteiden Mekaniikka

This paper opens up the history of structural analysis and dynamics simulations of Wärtsilä engines. It cites already published articles and theses with some backgrounds information. It also discusses some of the backgrounds of the in-house tool de

Modelling of Lateral Dynamics of Modular Heavy Vehicle Combinations

Autor: Rahkola, Pekka, Mauri, Haataja

Publikováno v: Rahkola, P & Mauri, H 2007, Modelling of Lateral Dynamics of Modular Heavy Vehicle Combinations . in Proceedings of the 11th European Automotive Congress, EAEC 2007). Budapest, Hungary, 30 May-1 June 2007. CD . EAEC, GTE, FISITA, Budapest, Hungary, 11th EAEC European Automotive Congress, EAEC 2007, Budapest, Hungary, 30/05/07 .

This study focuses on the affect of vehicle combination configuration and loading parameters on handling and stability. The behaviour of vehicle combinations is studied with open- and closed loop manoeuvres using multi-body models. Experimental measu
