A Review on the Impact of Bio‐Additives on Tribological Behavior of Diesel Fuels
Advances in Tribology, Volume 2024, Issue 1, 2024.Automobile engines require lubrication to lessen the impact of friction due to the high levels of wear and frictional heat generated by the sliding parts. Wear and friction will cause engine parts to endure for less time, be less reliable, and require more maintenance. Diesel fuel can potentially be replaced with biodiesel among other fuels.

TVMS Calculation and Dynamic Analysis of Cracked Gear considering Oil Film Stiffness
Shock and Vibration, Volume 2024, Issue 1, 2024.A time‐varying meshing stiffness (TVMS) model that includes oil film stiffness in the elastohydrodynamic lubrication (EHL) line contact is proposed for tooth root cracking. This model employs the oil film thickness to estimate the stiffness of the oil film in gear contact by considering the profile variation of the oil film induced by tooth root cracks,
