June 2011. The papers that were presented during the SICFP'11 in May and the VDI conference in June 2011 are now available for all to read. Please click here to request your free copies.

May 2011. During the International VDI conference ‘Transmissions in vehicles’ Peter Achten of Innas will be presenting the results of a study for which a detailed simulation of a large 33 metric ton wheel loader, carrying out the short loading cycle, has been performed. Two different power drive systems were compared: a conventional mechanical transmission and the new CPR-system with energy recuperation and hydraulic transformers. The main conclusions of this study can be viewed in the picture to the left.
For this study Innas worked together with Kim Heybroek of Volvo Construction Equipment (Sweden), co-author of the paper. The presentation is scheduled for the second day of the conference, wednesday June 8. For more details on the VDI conference taking place in Friedrichshafen, Germany, please click here.

April 2011. Peter Achten and Georges Vael of Innas will be present at the Twelfth Scandinavian International Conference on Fluid Power. On wednesday, May 18, Georges Vael will be giving a presentation on the E-Hydrid in session A1, at 1PM. Peter Achten will be presenting the efficiency measurements of the Hydrid pump/motor on friday, May 20th, at 8:30 AM in session A6. For more details on the conference, please click here.

November 2010. The first measurements of the new, fixed, 24cc, four quadrant floating cup unit have just been completed. The fixed unit was tested during pumping operation. Measurement were executed at two different inlet temperatures of 40ºC and 55ºC. At both temperatures an average efficiency of 93.5% was measured.

April 2010. Efficiency tests of the new Innas variable floating cup pump have just been completed. Experts at Eindhoven Technical University tested the new variable pump at different operating points. The variable pump proved to have excellent part load efficiency. The total efficiency of the 28 [cm3] type variable pump in case of full displacement shows high values in a wide band of the operating points, up to 95%.
At decreasing swash angles, the efficiencies also decrease, but only very gradually. This can be explained from the fact that in this new variable pump design there are no pressure dependent contact forces between the pistons and the ‘cups’ in which they run. Thus, an important source of friction as it appears in the more conventional types of axial piston units, is avoided in the floating cup concept.

December 2009. The Innas Hydraulic Hybrid (HyDrid) has been chosen to be one of the top products of the year in SAE's Off Highway Engineering (SOHE) magazine. In the November/December 2009 issue of SOHE editors highlight some of 2009's top offerings from the industry's component and system suppliers that were most popular among online readers of SOHE (www.offhighway-online.org). The Hydrid drivetrain technology is among the 20 best.

October, 2009. On the new web page Electric hydrid the answer can be found to a question frequently asked: Is the HyDrid concept competing with the electric vehicle technology? In our view, the HyDrid transmission does not exclude the electric battery. On the contrary, it facilitates the introduction of a base load electric system which can now be much smaller than of current hybrid electric vehicles. The combination of a hydraulic transmission and a 'leaner' electro motor and smaller batteries offers the best of both worlds.
