Gold valves for the Zhiguli engine!

It’s a strange idea to make highly loaded car parts from such a soft metal as gold. But still: Au is a special chemical element that humanity values ​​very much. Why not try if you have the money? No sooner said than done. We take a standard block of metal and cast blanks from it. The next stage is processing in a lathe. And the result is shiny products: at least take them to a jewelry store!


What's next? Naturally, installation in a standard Zhiguli engine: you need to check how the gold valves behave in a regular engine under appropriate loads. First, the parts need to be ground in, as they should be, using diamond (well, what else, Au?) paste.

Now comes the most crucial moment: starting the engine. Not right away, but it can be done. The first sensation is the quieter operation of the power unit compared to standard valves. After warming up the car started up better. The engine temperature has been brought up to operating temperature and now the car, which costs less than its valves, can be driven out onto the street for a ride. Tests - under normal road conditions: the engine is tested in different operating modes. And how did the trip end, what happened to the power unit and valves? Watch the video!
