        While there were numerous Knight licensees in the United States, Willys-Knight was by far the most successful, producing 50,000 cars or more each year, and at one point many believed the Knight system would obsolete the conventional poppet-valve engine (the kind we know).  That’s rather stunning to contemplate, as to modern eyes, the Knight engine is strange indeed. This is simply a brief—and clear, we hope—look at how it’s put together and how it works.

almost like a 2 stroke. imagine if it would work. the weak spot in alot of modern motors is the valve train and/or what is done to it for fuel economy and emissions. you sure dig up some cool stuff

  A friend of mine named Earl, had a Willys Knight, all nicely refurbished.  When I first  saw it, it as a far larger car that I anticipated.

  The Willys Knight slogan was "improves with use"..  Earl passed away about 2 years ago. ..Don't know what became of the Willys

   Willys was an innovative car builder, not afraid to try something new.. e.g. the Jeep..

  Before he was married, while dating my Mom, my Dad had a Whippet, made by Willys. Irony.. Whippet was a small car, and Dad was a big man...
