Currently, global warming has been a serious issue, which is closely related to anthropogenic emission of Greenhouse Gas (GHG) in the atmosphere, particularly Carbon Dioxide (CO2). To help achieve carbon neutrality by decreasing CO2 emissions, Oxy-Fuel Combustion (OFC) technology becoming hot topic recent years. However, few findings have reported about implementation OFC dual-injection Spark I...

The H2 internal combustion engine is gaining increasing interest especially for commercial vehicles. Regarding the optimization of process, results experimental investigations on a heavy-duty single-cylinder in combination with numerical 3D-CFD are presented. In addition to Direct Injection (DI) Spark Ignited (SI) configuration, Port Fuel (PFI) explored provide reference near homogeneous cylind...

The magnetic properties of layered-perovskite RbMnF4 have been investigated by neutron powder diffraction. This compound exhibits a magnetic ordering below T,=3.7&0.2 K. The resolution of the magnetic structure at 1.5 K indicates that RbMnF; orders as a collinear antiferromagnet. The propagation vector is k=O and the magnetic moment of each sublattice has a value of 2.97( 3) pfi The strong redu...
