cooled. The pistons are of a simple design with crowns of chrome- molybdenum cast
steel and skirts of cast iron. The pistons are oil- cooled from the forced lubrication
system. The B. and W. turbocharging system for two-stroke cycle engines is a
flunctuating pressure system.

                                          Exercises

      I.     Answer the questions:

      1.What is the power output of the pressure- charged engines ?
      2. What are the main particulars of the B. and W. design ?
      3. In what way are the cylinders scavenged ?
      4. How is the fuel injection pump operated ?
      5. What material are the cylinder covers made of ?
      6. What valves are arranged in the cylinder cover ?
      7. What pistons are used in the engine ?

      II. Translate the following words and expressions into Russian:

       Exhaust – turbocharged, normally aspirated engine, reduction of fuel
consumption, a single – acting, exhaust poppet valve, cross head; a swirling motion, to
expell, centrally arranged, a bedplate, a frame, rigid longitudinal girder, steel through
bolts, to provide, fully- built; semi- built; torsional vibration, to operate, to actuate
cylinder cover, cylinder head, the crown, the skirt, a flunctuating pressure system.

      III. Form nouns from the following verbs:

       To inject, to arrange, to vibrate, to connect, to operate, to revolve, to reduce, to
apply, to locate, to separate; to receive, to support, to cool, to heat, to operate, to inject,
to actuate; to press, to measure.

      IV. Translate sentences into Russian. Pay attention to the Ving translation.

      1.Fuel delivery is regulated by varying the effective stroke- volume of the pump.
      2.The second row of scavenging ports is closed by mechanically driven valves.
      3.When operating the pistons move simultaneously either towards each other or
      away from each other.
      4.No essential results having been obtained, the scientists had to carry out some
      more experiments.
      5.Manoeuvring is carried out by a single lever for starting and reversing, the
      second lever being provided for controlling the speed of the engine by adjusting
      the fuel supply.
      6.In engines having more than six cylinders the crankshaft is built up in two
      parts.
