F02B25/14 » using reverse-flow scavenging, e.g. with both outlet and inlet ports arranged near bottom of piston stroke 135
F02B25/20 » Means for reducing the mixing of charge and combustion residues or for preventing escape of fresh charge through outlet ports not provided for in, or of interest apart from, subgroups to 45
F02B25/26 » Multi-cylinder engines other than those provided for in, or of interest apart from, groups to 10
