Artificial neural-network based modeling of variable valve-timing in a spark-ignition engine

Gölcü, Mustafa; Sekmen, Y.; Erduranli, P.; Salman, M.S. (Elsevier BV, 2005)

Variable valve-timing and lift are significant operating and design parameters affecting the performance and emissions in spark-ignition (SI) engines. Previous investigations have demonstrated that improvements in engine ...
Fatigue properties of spring reinforces polymer gears

Can, H; Mendi, F; Topcu, M (PAMUKKALE UNIV, 2005)

Failure of gears, occur surface pressure stress and fracture at base of teeth. For steel gears, it is known that process of carburizing increases fatigue strength. Internal stress on the surface increases of fracture fatigue ...
Effects of ethanol blended diesel fuel on exhaust emissions from a diesel engine

Can, O; Celikten, I; Usta, N (PAMUKKALE UNIV, 2005)
