Abstract
Automobile manufacturers are facing the problem of crankcase emission control in the 1963 model year. Testing has indicated that blowby gases consisting of high comcentrations of hydrocarbons are one of the primary causes of smog and air pollution.
A description of three systems under consideration — positive crankcase ventilation, tube type - valveless, and dual action ventilation — is presented in this paper. The basic function is to recycle the blowby gases back into the conbustion chamber for burning, either through the intake manifold, the air cleaner, or both. Test results indicate recycling of blowby gases is advantageous in that it results in cleaner engines as well as eliminating to a large degree hydrocarbon emission.
