In this System, oil is stored in the crank case. A small scoop is attached with the big end of connecting rod.
When the crank is rotated, the scoop dips in the oil and splashes the oil. The oil is splashed on cylinder wall, connecting rod ends and valve mechanisms. This method is used in some motorcycles and single cylinder stationery engines. Greater care should be taken that the oil in the crank case is filled up to the desired mark. There will be insufficient lubrication when the oil level is low.
Disadvantages :
* It is not efficient , if the bearing loads are heavy.
* It is very difficult to introduce oil in the minute gaps between the sliding surfaces.
