- Evaluation of PCV Systems by Field and Full-scale Laboratory Tests
抄録
The effects of PCV systems of domestic gasoline engines on performance of crankcase oils were studied by taxicab field tests and laboratory full-scale tests. These tests were run on three types of crankcase ventilation systems; road draft type, tube type PCV and valve type PCV. Three grades of crankcase oils, MM, MS and Supplement-1 class, were used.<br>The results obtained are as follows:<br>(1) Tube type PCV system showed a marked tendency to form a lot of oil insoluble sludge than valve type PCV system and road draft system.<br>(2) The combined additive formulations of ashless dispersants and metal salts detergents were effective to control sludge formation in the three crankcase ventilation systems.<br>(3) The NOC MS Test (modified MS Sequence V Test procedure using OHV Type engine) could utilize satisfactorily for the studies of the effect of crankcase ventilation systems and the evaluation of crankcase oils.
