reciprocating pistons and connecting rods.
The result is a «silky smooth», virtually
vibration-free engine.
The Saab 2.3-litre engine represents the
ultimate in today’s engine technology. Its
raw silky smoothness.
нейтрализует и сглаживает вибрацию,
вызываемую возвратно-поступа-
тельным движением поршней и
шатунов. В результате двигатель
освобождается от вибрации,
приобретая безупречную «шелковую»
плавность.
Двигатель Сааб объемом 2.3 литра
представляет собой последнее
достижение технологии двигателей.
Его мощность впечатляет также, как и
его плавность.
Exercise 12. Make up a reverse translation of the 2-nd paragraph of the text in
written form.
Exercise 13. Answer the following questions to the text.
1) Why can not the two piston pairs balance out one another perfectly?
2) What compensates for the resulting forces in the 2.3-litre engine?
3) How are the balancing shafts driven?
4) What counteracts and smoothes out the vibrations caused by pistons and
connecting rods?
Exercise 14. Speak on the vibration-free feature of the 2.3-litre engine, using the
following words.
Piston pairs, to balance out, crank mechanism, reversal positions, resulting forces,
counter rotating balancing shafts, chain, to rotate, to smooth out the vibrations,
connecting rods, smoothness.
Exercise 15. Summarise your knowledge of the Saab 2.3-litre engine. Discuss
with your partner the benefits of the Saab 2.3-litre engine. Use the following plan.
1) Maximum reliability in any climate.
2) The 16-valve injection engine.
3) The base of a new generation of 4-cylinder engines with balancing shafts.
4) Virtually vibration-free engine.
