   Exercise 15. Make up a reverse translation of the last paragraph of the text in
written form.

     Exercise 16. Answer the following questions to the text.

     1) Why is the design of the combustion chamber extremely favourable?
     2) What improves turbulence in the combustion chamber?
     3) What are the benefits of the four valve per cylinder design?
     4) What is the benefit of the spark plug being located in the centre of the
     combustion chamber?
     5) Due to what system the engine can be run on any grade of fuel?

   Exercise 17. Give general characteristics of the ideal combustion chamber using
the following words.

   Dome-shaped, flat piston crown, spark plug, fuel/air mixture, harmful, knocking,
compression ratio, pre-ignition, low fuel consumption, knock sensor, electronic
control unit, any grade of fuel.

   Exercise 18. Read the third part of the text. Translate it. Compare with the Russian
translation given to the text. Use it as a clue if necessary.
