... technologies. In the field of internal combustion engines, researchers and scientists are working constantly on new technologies such as downsized engines, homogeneous charge compression ignition, the use of biofuel, new engine component materials, etc., to improve vehicle performance and emissions...

...Arthur Francisco; Aurelian Fatu; Dominique Bonneau Reducing the frictional loss in internal combustion engines (ICE) represents a challenge, in which all car manufacturers are involved. This concern has two origins. The first one is the fuel cost, which increases over the years. The second...

...Jun Sun; Changlin Gui There is direct interaction between crankshaft and bearing in an internal combustion engine. The effect of lubrication status of bearing was not considered in the present calculation of crankshaft strength. A given oil film pressure distribution of bearing was generally used...

...Luis San Andres; Juan Carlos Rivadeneira; Kostandin Gjika; Christopher Groves; Gerry LaRue Turbochargers (TCs) improve performance in internal combustion engines. Due to low production costs, TC assemblies are supported on floating ring bearings (FRBs). TCs show subsynchronous motions...

... and the body of a connecting rod used in a high performance internal combustion engine (Fig. 2 ). This bearing was already analyzed in 10 11 , employing a detailed and continuous (i.e., not split into two parts) three-dimensional finite element structural model. Two versions of the plane stress model have...
