When John North Willys acquired the Edwards-Knight Company in 1914, he continued production of the car under his own name. Its inventor Charles Knight received a royalty of $100 on each car produced. The Knight sleeve valve engine had been used mostly on expensive luxury automobiles because it was smoother and quieter than normal 'popet valve' engines of the day. But as conventional engines were improved, the Knight was finally forced out of production by its high manufacturing costs and high oil consumption.
