     With exhaust gas turbocharging it has proved possible to triple the power
  obtained from the swept volume of a diesel engine.

  I. Прочтите и переведите текст письменно.
  II. Переведите предложения, обращая внимание на модальные глаголы и
  их заменители.
      1. Great care must be taken in case of reboring the cylinder.
      2. The maker’s instruction should be followed strictly as far as the cylinder
         reboring or resurfacing concerned.
      3. The modern diesel engine with its exhaust gas turbocharger can be regarded
         as a symbiosis.
      4. A distinction is to be made between a three-pulse turbocharging and four-
         pulse turbocharging.
      5. The design calculations have to begin with the main bearings and crankpin
         bearings.
      6. Some engines may be very sensitive to fuel-injection conditions, whereas
         other engines may have their injection conditions altered without materially
         affecting the performance.

     III. Исправьте те предложения, которые искажают смысл текста.
     Запишите правильный вариант. Переведите.

     1. Correct turbocharging is very important.
     2. The diesel engine uses that part of energy which has low pressure and
        temperature.
     3. The piston compresses the air to over 120 kg/cm2 and the temperature of
        15000C.
     4. Three-pulse and four-pulse turbocharging systems are mainly used today.
     5. With exhaust gas turbocharging it has appeared impossible to triple the
        output.

     IV.. Выберите из трех данных предложений то, которое является
ответом на вопрос. Укажите ответ буквой. Сделайте перевод.

     1.   Why can’t we call a modern diesel engine a simple reciprocating machine?
     a)   because it is very complicated.
     b)   because it is a combination of a diesel engine and gas turbine.
     c)   because most engines use supercharging.
     2.   When is the air cooled in the turbocharger?
     a)   It is cooled before the compressor.
     b)   It is cooled before the turbine.
     c)   It is cooled before inlet valves of the engine.
