I. Complete the following sentences according to the text:
The principle of supercharging is in supplying more air to …
The more air and fuel burn in the cylinder, the more …
By using a supercharger, the necessary amount of air …
A supercharger takes air …
A supercharger compresses the air to …
A supercharger delivers ...
A supercharged engine gets greater power for the same …
To increase the air pressure in a four-stroke engine, the air charge …
To obtain scavenge air in a two-stroke engine a …
In a two-stroke engine supercharging is obtained by ...
II. Replace the underlined words by their synonyms:
The more air and oil burn in the cylinder the more power is obtained from the engine.
To increase the air pressure in a four-stroke engine, the air charge is forced in by a higher pressure generated by a blower.
A two-stroke engine has a blower for receiving scavenge air.
A supercharger gets air out of the surrounding atmosphere, compresses it to a higher pressure and passes it to the valve or port of an engine.
A slight change of the exhaust and scavenge regulating is made in order to keep more scavenge air at the beginning of the compression stroke.
III. Answer the following questions:
What is the principle of supercharging?
What does supercharging increase?
How is the power output of a diesel increased?
What device is used for supercharging?
What is a supercharger?
What is the function of a supercharger?
What is a blower in a two-stroke engine used for?
How is supercharging obtained in a two-stroke engine?
IV. Put all possible questions to the following sentences:
Supercharging supplies more air to the combustion chamber.
The necessary amount of air is supplied into the cylinder by a supercharger.
A supercharger takes in air from the atmosphere.
A blower of a two-stroke engine obtains scavenge air.
A two-stroke engine has a blower to obtain scavenge air.
V. Give nouns corresponding to the following verbs:
Press, inject, ignite, supercharge, compress, blow, select, move, revolve, connect, permit, require, expand, develop, transmit, occupy, produce.
VI. Speak about:
a supercharger,
supercharging in a two-stroke engine,
supercharging in a four-stroke engine.
VII. Translate into English:
Продувка двигателя используется для подачи большего количества воздуха в камеру сгорания.
Для продувки двигателя используется специальное устройство.
Это устройство называется компрессором (нагнетателем).
Он забирает воздух из атмосферы, сжимает его, и подает в двигатель.
Мощность двигателя увеличивается продувкой.
При использовании нагнетателя в конструкции четырехтактного двигателя требуется изменение в регулировке клапанов.
Впускные и выпускные клапана конструируются для одновременного открывания от 80 до 1600 градусов.
В двухтактном двигателе для получения продувочного воздуха используется воздуходувка.
Продувка достигается увеличением количества и давления продувочного воздуха.
Что представляет собой продувка двигателя?
Что используется для увеличения количества и давления продувочного воздуха?
Что представляет собой нагнетатель?
Какое устройство используется для продувки двухтактного двигателя?
Каков принцип продувки двигателя?
Какова функция компрессора?
Каково назначение продувки?
Каково изменение в регулировке впускных и выпускных клапанов?
