5. There is a word out in each line. Find all the four:

An internal combustion gasoline engine works by burning mixture of gasoline and air. The produced heat causes the air to expand and force move down the piston. One movement of the piston is called a stroke. Most cars have a 4-stroke engine. Many light motorcycles have 2-stroke engines. A 2-stroke engine is simpler in construction, it has no inlet valves. But it is not very powerful.

Information

Read with a dictionary and translate it into Russian:

The exhaust and silencer

The exhaust gases leave the engine at high pressure, and would produce intolerable noise if allowed to escape directly. The exhaust manifold therefore conducts the gases to the silencer, where they pass through a series of holes in metal plates or tubes. This reduces the pressure of the gases so that they leave the silencer quietly.
