Connecting Rod Bearing Lubrication

The lubrication of bearings is very important to engine service life because it forces oil to high friction points within.
Connecting rod bearing lubrication. The piston pin bearing in the connecting rod is of the full round or bushing type. Journal bearings are one of the most common types of hydrodynamic bearing. Ucl engineering challenge 1 individual video assignment. To aid lubrication the upper bearing surface of the bushing if so equipped may be grooved to form a reservoir for collecting oil that enters through a drilling in the rod eye.
On connecting rod bearings the upper bearing half is installed in the rod and the lower half is placed in the rod cap. However the actual engine especially vehicle engine does not always operate in rated operating condition and its operating condition changes constantly. Lambda oil primer nano e. Only the lubrication performance at rated engine operating condition was generally analyzed in current design and research of engine connecting rod and main bearing.
