DESC:TECHNICAL FIELD
The present invention relates to reduction of vibration levels in an engine by way of composite materials. More particularly, the present invention relates to reduction of restriction in the power train components (rotation of crankshaft and piston) during operation by reducing oil splash.
BACKGROUND
The vibration that is generated in the interior of a vehicle reduces the user’s ride comfort. The structural vibrations are caused due to the loosening of mounts. The two types of vibrations caused at the engine are: torsional and longitudinal vibrations. The cylinder pressure is increased by the rotation of the crankshaft, as the piston approaches top dead center on the compression stroke. Just after that the ignition and combustion increases the pressure and the pressure start to decrease when the piston moves down to bottom dead center.
In an engine system, the follower is kept pressed against the cam surface by means of a retaining spring. Due to inertia of the follower, beyond a particular speed, during a part of cam rotation, the follower may lose contact with the cam, which is a type of vibration. This is a transient condition that occurs only with high speed engine.
The lubrication system plays a key role in maintaining peak performance of engines. Proper lubrication ensures reliability and longevity. Engine oil reduces operating temperature and friction between components for better performance and longer life.

Oil pan is one of the source of vibration and in cases it being structural item and it transmits vibration to the Engine and this vibration is reduced by introduction of this plate.
The technology existing in the prior art causes a great amount of oil splash from the oil pan to the block and are highly complex and cost consuming.
OBJECTIVE
The primary objective of the present invention is to reduce the vibration levels in an engine.
Yet another objective of the present invention is to reduce restriction in the power train components during operation by reducing oil splash.
The instant invention achieves the object by designing and assembling a plate that reduces oil splash from the Oil sump into the block at different gradient levels and also reduces the vibration levels of the engine acting as a damper between Oil Pan and Cylinder Block.
SUMMARY
According to the present invention, a plate is designed and assembled between the engine block and the oil pan. Said plate acts as a vibration reducer by absorbing the vibration and also avoids oil splash from the pan back to the block.
According to the instant invention, the said plate provides for a dual solution of reduction of vibration levels in the engine as well as oil splash along with weight reduction.
