level or lower than exhaust ones. The fresh air-charge is pumped into the cylinder at low pres-
sure by means of a scavenging pump or a low pressure scavenging air compressor, which may
be driven either by the engine itself, or by a separate auxiliary engine or electric motor. This air
not only provides the air charge necessary for the proper combustion of the fuel but assists in
clearing the burnt gases rapidly out of the cylinder.

      I. Translate into Russian.
      Compression occurs, upstroke (downstroke) of the piston, during the latter part of the
downstroke, to be made possible by substituting opposite sides of the cylinder, in some de-
signs, on the same side, low pressure scavenging air receiver, to be slightly higher, to be unco-
vered by the piston, to be still closed, with the result that, to be inclined upward, to direct, to be
positioned tangentially, to be partially open (closed), valve-controlled scavenging ports, no ex-
haust gas can flow out, however, pressure-controlled valve, to drop below that in the receiver,
mean effective pressure.

      II. Give antonyms to the following words.
      Upstroke, inlet, to disconnect, bottom, to cover, to blow in, advantage, partially, below,
to increase, usual, high, necessary, fall, before, short.
