Downsized spark ignition engines have the benefit of high thermal efficiency; however, severe engine knock is a challenge. Ethanol, a renewable gasoline alternative, has a much higher octane rating and heat of vaporization than conventional gasoline,

Gas-to-liquid (GTL) naphtha can be used as a gasoline blend component, and the challenge of its low octane rating is solved by using ethanol as an octane booster. However, currently there is little knowledge available about the performance of gasolin

In the recent years the capability of laser manufactured micro-structures to reduce friction has been investigated. The aim of this paper is to investigate the potential of surface texturing through ultra-short-pulse laser ablation to improve the per

The European Union overall greenhouse gas (GHG) emission target is an 80 % – 95 % reduction from the GHG emissions emitted in 1990, the German target of 95 % reduction is even tougher.

This study investigates how the beneficial effects of laser-manufactured surface microstructures on friction vary with varying oil temperature. Laser surface texturing (LST) is a favorable method to optimize friction and wear, which have always been
