**New Auto Motor**

Motor fuel costs can be cut to 5 cents a gallon, claims Walter
S. Rohn, consulting engineer, of Needham, Mass., with an amazing
new automobile motor he has invented that has no spark
plugs  nor connecting rods. Like huge Diesel engines used
to power ships, it will burn low-grade oil instead of gasoline.
An odd-shaped cam on the crankshaft receives power directly from
a roller mounted on the piston. Heat generated by terrific
compression ignites the fuel in a "slow" explosion.
