•Dissimilation partition laser textured cylinder performs better than plateau honing cylinder.•LST-1 and LST-3 laser texturing cylinder performs better in oil consumption than the origin.•LST-3 textured cylinder performs better in speed performance than the other cylinder.•The comprehensive performance of LST-3 laser texturing cylinder is the best.
The effect of discriminating partition laser surface micro-texturing (LST) was investigated on engine comprehensive performance. The cylinder bore was divided into five different sections according to wear characteristics and lubricating performances and three schemes of LST partition were designed on the cylinder surface. The performance test bench shows that the diesel engine equipped with the three different LST cylinders have different decreasing amplitude in fuel consumption compared to the standard cylinder. The maximal oil consumption is decreased by 45.5%. A significant reduction in specific fuel consumption of the engine is observed with the laser microtextured cylinders compared to that of the standard cylinder. The comprehensive performance of the diesel engine fitted with LST-3 cylinder establishes the best performance.
