Exercise 23. Make up special questions according to the models and answer 
them to streamline your speaking skills.
Model A:
Modern internal combustion engines can be classified in a number of 
different ways.
 
How can modern internal combustion engines be classified?
1. Engines of two different cylinder arrangements can be classified as 
W-type engines. 2. According to the type of cooling, engines can be divided 
into air-cooled engines and liquid-cooled engines (water-cooled engines). 
3. A modern engine also might be called a reciprocating, spark ignition, four-
stroke cycle, I-head, water-cooled, gasoline, multipoint fuel injected automo-
bile engine. 4. Opposed-cylinder engines can be called flat engines. 5. Accord-
ing to the type of ignition, engines can be divided into spark-ignition engines 
and compression-ignition engines.
Model B:
This engine uses a combination of natural gas and diesel fuel.
 
What does this engine use?


225
1. A single combustion process causes two power strokes at the same 
time. 2. An opposed-cylinder engine
 
contains two banks of cylinders opposite 
to each other on a single crankshaft. 3. Such common fuel as gasohol consists 
of 90% gasoline and 10% alcohol. 4. This engine runs on diesel oil. 5. Basic 
design divides engines into reciprocating and rotary ones
.
Exercise 24. Ask questions and use the words in italics in your answers. The 
words in brackets will help you.
1. The first internal combustion engine ran on 
coal gas 
(what fuel). 2. 
Éti-
enne Lenoir
created the first commercially successful internal combustion 
engine (who). 3. A four-stroke cycle engine involves 
four
piston movements 
over two engine revolutions for each cycle (how many). 4. 
Power
is delivered 
to a rotating output
 
crankshaft by mechanical linkage with the pistons (what). 
5. Opposed-cylinder engines are often called 
flat engines 
(how).
