Abstract: A continuously variable rear axle allows for increasing the number of rear axle ratios, and thereby further allowing low drive ratios for high speed, low torque applications, and high ratios for low speed, high torque situations utilizing otherwise industry standard transmissions.

Abstract: Diesel engine particulate trap regeneration is obtained by concurrently supplying two exhaust gas streams to a particulate trap requiring regeneration. One stream is produced in a reactor/diesel engine operating an efficient stoichiometric ratio. The second stream is produced in a second reactor/diesel engine burning fuel at a low air/fuel ratio to produce an exhaust gas stream carrying a substantial load of unburned hydrocarbons, hydrogen and carbon monoxide. The two streams together carry sufficient thermal energy to ignite the unburned hydrocarbons, hydrogen and carbon monoxide using oxygen from the first exhaust gas stream as oxidizer.
