Discover the Best Brake System for a 70Kw Engine Dyno Design

AI Thread Summary
For a 70Kw engine dyno, a friction brake with pneumatic actuation is a viable option. Common brake systems used in commercial engine dynos include eddy current brakes and hydraulic brakes. The Dyno Dynamics twin retarder utilizes eddy braking, which is effective for controlling engine RPMs under load. It's essential to measure engine torque accurately using a strain gauge. Selecting the right brake system is crucial for optimal performance and control in engine testing.

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?

Thanks

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.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
