    Cooling system test lab

    I wonder if anyone could point me to a test lab in the US that can do heat rejection testing on automotive radiators. I'm trying to decide between three sample designs, and could use some actual measurements.

    Bellville Lock Washer

    Thanks for the input, guys. The bellville washer would be hardened and serrated, that's easy enough. The filter head componentes are aluminum, which is why I have a concern about thermal effects. The filter will be screwed into the outer half of the unit, which will mount horizontally. I need...

    Bellville Lock Washer

    I'm designing an oil filter head for a six cylinder motor. The head will be made in two pieces, I'll be fastening them using low grade steel bolts. I'm thinking of adding a bellville under the bolt head to compensate for thermal expansion and contraction of the parts. I don't think locktite...

    Yet another alternative engine

    http://www.regtech.com/index.html I wonder what sort of material they might use for the vanes.

    Radiator design reference

    I am designing a series of downflow radiators. It's been suggested that the radiators would work best if the inlet and outlet were at opposite corners. The best "fit" solution would have the inlet and outlets both on the left side of the radiator. I understand that there will be pressure loss...

    Who 'Invented' Metric

    Surprisingly, base 12 originates from an ancient method of finger counting, first documented in Babylon, but probably much older. No, they didn't have more fingers back then. If you examine your fingers, you will see that each finger is divided into three joints. Using your thumb as a pointer...

    Did the Romans have engineers?

    Skim through some of the ancient literature, Vitruvius, Archimedes, Ptolemy, and you will quickly come to appreciate that the ancients excelled in both engineering and mathematics. Roman construction materials were manufactured to an Imperial standard. Construction methods reflected an...

    Hydrogen Power

    It seems to me that the only good point about a hydrogen economy is that you have a common delivery mechanism for multiple sorts of input fuel. You DON'T eliminate emissions if your source fuels are coal, gas or petroleum,and these are the most likely choices in the short run. So the hydrogen...

    Bar and Plate (plate fin) radiators ?

    Stacked plate radiators were used in a few cars in the 1960s. According to Dewitt's, a copper radiator for a Corvette can handle 3300 btu/m vs 4600 btu/m for a stacked plate radiator of the same size. If these numbers are right, I would expect bar and plate would produce similar results I'm in...

    Galvanic corrosion in glycol solution

    I'm designing a thermoswitch adapter that will be used to control an electric fan in automobiles. The adapter mounts in a header tank, which can be steel, aluminum, or brass depending on model and vintage. The switches are always brass cased, and screw into the adapter. The adapter is (or...

    Fuel Filler door

    Once upon a time, there was a theory that left hand drive cars should have the door on the right, right hand drive on the left. The idea was that a LHD car was more likely to be involved in an accident where the left side of the car was compromised. I don't think this idea had legs, but I think...
