← TechnologyWhich outcome occurs more rapidly when sustained pressure in a diesel engine cylinder exceeds piston ring strength?
A)Increased blow-by gas leakage occurs✓
B)Volumetric efficiency will drastically improve
C)Lubricant oil viscosity stabilizes quickly
D)Soot formation in exhaust decreases
💡 Explanation
Increased blow-by gas leakage occurs because pressure overcomes the piston rings' ability to seal, resulting in gases escaping into the crankcase via pressure differentials. Therefore, leakage occurs, rather than improved efficiency or alterations in oil properties or exhaust byproducts, which would only indirectly correlate.
