Fuels, Lubricants, and Positive Crankcase Ventilation Systems 640261

Current positive crankcase ventilation systems were evaluated for their performance difficulties and their effects on fuel and lubricant requirements. These systems promote the formation of deposits in the carburetor and cause corrosion in the crankcase. Carburetor fouling can be minimized by an effective detergent in the fuel. Engine corrosion can be minimized by the use of high quality lubricants containing balanced additives of high buffering capacity. The performance difficulties associated with the malfunction of these systems may be minimized by adequate maintenance.
