    EGR Anti-lag?

    I have heard mention of "EGR Anti-lag" systems being utilized on WRC rally cars, but I cannot find any details about how they work. The only thing I have read is that they recirculate exhaust gasses back to the turbo manifold through a 'cat-like' device to burn residual fuel and increase...

    Water Density/Viscosity Table

    I'm looking for a table of known density and viscosity values for water at temperatures from 25 to 80C in 5C intervals. If anyone has a resource, whether online or in a book, please let me know.

    Calculate sliding caliper like 2-pot?

    This makes sense in my head, but I just wanted to bounce it off you guys to make sure it's correct. With a sliding caliper, the piston pushes the pad it is in direct contact with against the rotor. Then, once it's contacted, the caliper body slides until the other pad is in contact with the...

    Idea for offsetting solar/wind with grid power...

    I'm an auto/mech engineer, and have only had a couple circuits classes, so please forgive me if I'm talking out of my you-know-what. But, easily-integrated 'green' power generation interests me, so here I am, trying to learn... When a solar panel or wind turbine is added to a home, it's either...

    Load calculation for control arm design?

    I'm wanting to design some control arms for a track day car, but I'm unsure of what to use for the loads for the FEA. The advice I got was to use 4-3-2 as maximum load multipliers, and to assume the car corners at 1.5G's (higher than the actual). My problem is that I don't know how to...

    NX3 Motion joint limits?

    Hi, I am wanting to impose a displacement restriction on a slider joint, but am having no luck in doing so. I have tried all of the different motion drivers and modifying the limit and displacement values, but have not been successful. I have checked the UG documentation and have searched online...
