Mystery Engines

The passion of motor makers to improve their product, and do it in a hurry too, has created in Detroit deep interest in an lleged "mystery car," which is said to be revolutionary in design and about to be produced by a Detroit motor concern.

The consensus of opinion indicates that the new motor will have a single sleeve-valve engine. This engine was perfected in Scotland, and has been widely used in the "Argyll" car abroad. Louis Chevrolet, automobile builder, has recently been trying it out with a view to adapting it for U. S. use.

The "Argyll" is said to require only 28 moving parts. Its engine consists of a single sleeve-valve of cylindrical form, having ports at the top and a single universal driving connection at the bottom.
