Interactions of Ethanol with Friction Modifiers in Model Engine Lubricants

open access: yesLubricants, 2019
When employed as an engine fuel, ethanol can accumulate in the lubricant during use. Previous work has shown that ethanol contamination affects friction and elastohydrodynamic lubrication (EHL) film formation, and also the growth and stability of anti ...

Numerical Study on the Effect of Fuel Rich n-Heptane on In-Cylinder Fuel Reforming Characteristics in an HCCI Engine

open access: yesInternational Journal of Chemical Engineering, 2021
The effect of in-cylinder fuel reforming on an n-heptane homogenous charge compression ignition engine has been studied. A dedicated cylinder without a complex control system is proposed for fuel enrichment reforming, which can provide part of the power ...

Challenges in charge preparation and combustion in homogeneous charge compression ignition engines with biodiesel: A review

open access: yesEnergy Reports, 2019
Homogeneous charge compression ignition (HCCI) engines have high efficiency and lower NOx-soot emissions than diesel and gasoline engines. However, these engines suffer from high HC, CO and unregulated emissions and combustion phasing control.
