REVIEW ON INTERNAL COMBUSTION ENGINE VIBRATIONS AND MOUNTINGS

Ride comfort, driving stability and drivability are vital factors in terms of vehicle performance and the customer satisfaction. The power plant (IC engine) is the source for the vibration that reduces the vehicle performance and it need to be controlled to some extent such that the vehicle performance will be improved. The IC engine is made up of reciprocating and rotating parts and they produce unbalanced forces during their operation and produce the vibratory output at the vehicle supporting members. The vibration reduction will be possible by minimizing unbalanced forces and by providing the anti vibration mounts at the engine-vehicle interface. Many researches were made to find the causes for the vibration and to reduce the vibrations at the engine supports. But still there is a research gap on the vibration modeling and vibration isolation of the engine. In this work, an attempt is made to represent the state-of-the- art for the engine vibrations and its isolations and to provide a gate way for the future work on it. It reveals the various work carried out on the engine multibody modeling of the IC engine components and different engine mountsand their orientations. The review is structured as engine multibody modeling, engine vibrations and engine mounting areas and revealed the gaps and untouched parts that requires further research
