Design of a engine dyno

  1. Feb 15, 2014 #1
    Hi all,

    I'm designing a 70Kw engine dyno and I'm thinking to use a friction brake with a pneumatic actuation. Which kind of brake system usually have such commercial engine dyno? Eddy current brake? Hydraulic one?

    Our dyno dynamics twin retarder uses eddy braking.

    All you need is to be able to control the rpms of the wide open engine with the load and measure the torque of the engine with a strain gauge.
