The K-D Motor Company, manufacturers of the with the little known K-D engine, founded in 1912 by Miss Margaret E Knight and Mrs Beatrice Davidson, was legally “dissolved by Proclamation”. The K-D automobile was a large 137 inch wheelbase five passenger Touring car with wire wheels. Very few K-D automobiles were made and their cost – $6,000.00. The K-D engine invented by Knight and Davidson was a four cylinder with a four inch bore and a six inch stroke. It was a non-poppet type with a reciprocating sleeve at one side to admit the mixture and a similar sleeve on the opposite side for the exhaust. These sleeves are reciprocated 2 inches at half crankshaft speed, and were located between two stationary cylinder walls. The piston reciprocates within the inner cylinder wall. The outer cylinder is water jacketed and is cast integrally with the cylinder head and is removable.The K-D engine had one more peculiarity. The bottom of the main or inner cylinder is enclosed beneath the piston and is also water jacketed. The exhaust gases instead of being direct from the combustion chamber above the piston are connected to the space beneath the piston and used to force the piston up, thereby acting as a double acting motor.
