  We present the complete set of thirty four ASCA observations of non-magnetic
cataclysmic variables. Timing analysis reveals large X-ray flux variations in
dwarf novae in outburst (Z Cam, SS Cyg and SU UMa) and orbital modulation in
high inclination systems (including OY Car, HT Cas, U Gem, T Leo). We also
found episodes of unusually low accretion rate during quiescence (VW Hyi and SS
Cyg). Spectral analysis reveals broad temperature distributions in individual
systems, with emission weighted to lower temperatures in dwarf novae in
outburst. Absorption in excess of interstellar values is required in dwarf
novae in outburst, but not in quiescence. We also find evidence for sub-solar
abundances and X-ray reflection in the brightest systems. LS Peg, V426 Oph and
EI UMa have X-ray spectra that are distinct from the rest of the sample and all
three exhibit candidate X-ray periodicities. We argue that they should be
reclassified as intermediate polars. In the case of V345 Pav we found that the
X-ray source had been previously misidentified.
