10 years ago i first heard about this, and i did research. At the time, there was a video that could be found of a brass era car which had a T head combustion chamber with a central expansion cylinder. You could hear it running and it was near silent. This did make it into cars, it didn't just lie dormant for 124 years, only about 100.
