CARD #5

  Task 1.

1. Introduce yourself. 

2. Why do you choose this profession?

 

I didn’t choose. I wanted to become a teacher, but, as usual, parents decide who you will be. Over time, I get used to the fact that in the future I will work as an aviation mechanic.

 

Я не выбирал. Я хотел стать учителем, но, как обычно, родители решают, кем вы будете. Со временем я привыкаю к тому, что в будущем буду работать авиационным механиком.

 

Task 2.

1. What are the components of combustion engine?

The outer shell of the engine includes an engine block, a crankcase, and a head. Inside the engine is a spark plug or glow plug, valves, cylinder, connecting rod, crankshaft and piston.

 

Внешняя оболочка двигателя включает в себя блок двигателя, картер и головку. Внутри двигателя находится свеча зажигания или свеча накаливания, цилиндр, шатун, коленчатый вал и поршень.

2.What is the difference between gasoline and diesel engines?

The construction of combustion engines differs depending on the fuel type. The primary differences are in the cylinders. In a gasoline engine, fuel is ignited by a spark plug. In deasel engines, pressure alone is enough to initiate combustion.

 

Конструкция двигателей внутреннего сгорания различается в зависимости от типа топлива. Основные отличия заключаются в цилиндрах. В бензиновом двигателе топливо зажигается свечой зажигания. В дизельных двигателях одного давления достаточно, чтобы инициировать сгорание.

 

Task 3. Match the words and definitions.

1. A type of energy that is active or moving                   c)

2. The energy stored in an object that is stretched or bent d)

3. A unit of measurement for heat energy                       a)

4. To combust or catch fire                                                     e)

5. A set of rules describing the natural behavior of heat energy b)

 

a)BTU b) laws of thermodynamics c) kinetic energy d) elastic potential energy e) burn

 

CARD #6

Task 1.

1. Introduce yourself. 

2.How did you become interested in a mechanical engineering?

 

Actually, I was not interested in mechanical engineering. But it so happened that I entered the Academy of Civil Aviation in this specialty. And this specialty is very serious, and it must be handled correctly. I try to do this, more and more I am interested in this profession.

 

На самом деле я не интересовался машиностроением. Но так получилось, что я поступил в Академию гражданской авиации по этой специальности. И эта специальность очень серьезная, и с ней нужно обращаться правильно. Я стараюсь это делать, все больше и больше меня интересует эта профессия.

 

Task 2.

1. How does two-stroke engine work?

 

The two-stroke engine completes its power cycle in one crankshaft revolution. First, the piston compresses the fuel and air. Then, the spark plug fires. This ignites the compressed fuel. The force of the combustion pushes the piston downward, turning the crankshaft. The exhaust from the combustion is released from combustion chamber. At the same time, the inlet allows more fuel and air into the cylinder. The cycle is repeated.

Двухтактный двигатель завершает свой рабочий цикл за один оборот коленчатого вала. Сначала поршень сжимает топливо и воздух. Затем свеча зажигается. Это зажигает сжатое топливо. Сила сгорания толкает поршень вниз, поворачивая коленчатый вал. Выхлоп от сгорания выходит из камеры сгорания. В то же время впуск позволяет больше топлива и воздуха в цилиндр. Цикл повторяется.

 

2.give the definitions to the words: fuel, exhaust.

 

Fuel - a material that is used to produce energy by burning it.

Exhaust – the leftover gas or vapor from combustion.

 

Task 3. Convert affirmative sentences to negative ones.

1. That waiter has been speaking on the phone since 2 o’clock. The waiter does not speak on the phone from 2 o’clock.
2. You have broken my notebook. You did not break my notebook.
3. The train is going too slow.   The train does not go too slowly.
4. I am playing billiards with my brother now. Now I do not play billiards with my brother.
5. Lara lives with her parents in Madrid.   Lara does not live with her parents in Madrid.
