Lorenz Meckl How His Invention Impacted the Automobile Industry

Abstract

In 1938, Lorenz Meckl invented the Engine Intake Attachment for automobiles, which some 30 years later was used as a basis for other inventions by other inventors that eventually became the Positive Crankcase Ventilation (PCV) system, a control device for vehicle emissions. Meckl conceived an invention that was a means for improvement of the process of the internal combustion engine. One of the objectives of this was to recover a portion of this "combustible fuel from the crank case vapors” and to recycle it back to the cylinders to supplement incoming passage from the engine's carburetor.  The use of this device improved the economic and efficient process of internal combustion engines.  Meckl's invention improved automobile gas mileage by recycling crankcase gas fumes back into the carburetor, thereby reducing emissions.
