High Vibration Phenomena due to Cylinder Explosion Pressure of Low-speed Diesel Engine with 7 Cylinders installed on Land

open access: yesTransactions of the Korean Society for Noise and Vibration Engineering, 2007
A 7K60MC-S low speed diesel engine in a power plant has frequently experienced high vibration since the unit completed construction works. Up to date, no fundamental vibration solutions were reached. Hence, several vibration tests and analyses were conducted to identify the root cause of this high vibration and to suggest the optimal countermeasures ...

Simulation of The Effects of Valve Timing Misalignment on Performance in Spark Ignition Engines

open access: yesEngineering Perspective
Engine performance can be improved by changing the valve opening (or closing) timing without any cam profile changes. In this study, a simple simulation model was created for valve timing misalignment, which is an assembly defect in the engine.
