    parasitic losses

    Hi tbuelna, I know 5-10W is insane and I do not intend to measure in that range. I already had some indication of what to expect, but your pdf is very welcome We are looking in to the power lost or transmitted to the auxiliairies. We are builing an accurate Sankey diagram, and one of the losses...

    parasitic losses

    Hello ivymike, We already thought of driving the complete fead for a first judgement. Switching on and of the auxilliairies is one of the possibilities we are concidering. We do not have enough space to replace the crank pulley with a complete electric motor. We can however replace the main...

    parasitic losses

    Hello Mike H, the measurements must be reasonably accurate. We are trying to find losses with an accuracy of 5-10 Watts. But for first judgement in the range of 100 Watts. Our budget is not unlimited, but I believe it to be sufficient. We can buy sensors (we have logging equipment) or lend...

    parasitic losses

    We are going to measure the parasitic losses in a drivetrain with an IC engine. one of the topics is the loss due to belt driven pulleys. I could measure torques at all the pulleys with rpm or velocity of the belt. Are there any other methods I could use?

    RWD Subaru Boxer Transmission

    Use the 5-speed gearboxes, they're the strongest. Be aware that the early 5-speed boxes that came with the STI engines didn't have hardened teeth on the 4th and 5th gear sets. The centre diff can be easily replaced with a solid piece of axle. Pull out the front diff and weld up the exits. Now...

    electromagnetic dampers

    The project I am involved in, consists of gathering information about electromagnetic dampers for road going vehicles. I already know of the systems thought of by Bose an Renato & Emanuele Calzolari. (Italian) Some help of where to look for other systems would be very much appreciated. Regards...

    "Link-X" suspension

    maybe I am completely wrong, but isn't it also true that a swaybar controls wheelloads in corners? As one wheel travels in more than the other, the wheelload is compensated by the anti swaybar. I can imagine the x-link setup has no compensation for wheelloads when cornering. Offcourse the...
