4.1.Câu hỏi loại 1
1. The four stroke cycle
Induction stroke with the inlet valve open and the
exhaust valve shut, the piston moves down the cylinder
create a partial vacuum. This partial vacuum draws in the
atomized fuel from the carburettor into the cylinder.
Compression stroke w i both the i l t and exhaust
th n e

ng
the f l m i
ue xture . Just before the end of the stroke , an
electric spark across the poi ts of the sparki
n ng pl
ug
i ite s the petro l and ai m i
gn r xture .
Power stroke Both valves remain closed. During the tiny
interval of time required for flame to establish itself, the
piston has reached its highest position in the cylinder. The
gas generated by the burning fuel now expands rapidly,
driving the piston down the cylinder. This downward push is
converted into a rotary movement by the connecting rod and
crankshaft. A water jacket contained within the cylinder
walls helps to conduct away the heat generated during this
burning and thus keeps the engine cool.
Exhaust stroke The exhaust valve opens but the inlet
valve remains shut. The piston moves up the cylinder,
pushing the exhaust gas out through the exhaust valve. With
the completion of the exhaust stroke the cycle begins again.
a. Answer the questions:
1. Say which word in the text has the same meaning as “a
flash of light”
2. Find in the text which word means “produced”
3. In the text which word has the same meaning as “closed”
4. In power stroke what causes the piston to move down the
cylinder?
5. There are three differences between Induction and
Exhaust stroke. What are they?
b.Are these sentences True or False ? Write T (True) or F
( False) at the end of the sentence.
1. During the process of induction stroke, the inlet valve
and exhaust valve open at the same time.
2. The fuel mixture is compressed by the piston.
3. The piston moves down the cylinder when the gas expands
quickly.
4. Some water is placed outside the cylinder to conduct
away the heat and keep the engine cool.
5. After the exhaust gas has been totally released, a new
cycle begins.
2. Consumption of energy resources, (e.g. turning on a
light) is apparently harmless. However, producing that
energy requires resources and contributes to air and water
pollution. Many electric power plants burn coal oil or
natural gas in order to generate electricity for energy
needs. While burning these fossil fuels produces a readily
available and instantaneous supply of electricity, it also
generates ai poll tan ts i ud i
