"The Engine"
The greatest number of cars use piston engines. The four-cycle piston engine
requires four strokes of the piston per cycle. The first downstroke draws in the petrol
mixture. The first upstroke compresses it. The second downstroke—the power stroke—
following the combustion of the fuel, supplies the power, and the second upstroke
evacuates the burned gases. Intake and exhaust valves in the cylinder control the intake
of fuel and the release of burned gases. At the end of the power stroke the pressure of the
burned gases in the cylinder is 2.8 to 3.5 kg/sq cm. These gases escape with the sudden
opening of the exhaust valve. They rush to a silencer (muffler), an enlarged section of
piping containing expanding ducts and perforated plates through which the gases expand
and are released into the atmosphere.
Greater smoothness of operation of the four-cycle engine were provided by the
development of the four-cylinder engine, which supplies power from one or another of
the cylinders on each stroke of the cycle. A further increase in power and smoothness is
obtained in engines of 6,8,12, and 16 cylinders, which are arranged in either a straight
line or two banks assembled in the form of a V.

"Carburation".
Air is mixed with the vapour of the petrol in the carburettor. To prevent the air and the carburettor from becoming too cold for successful evaporation of the fuel, the air for the carburettor is usually taken from a point close to a heated part of the engine. Modern carburettors are fitted with a so-called float-feed chamber and a mixing or spraying chamber. The first is a small chamber in which a small supply of petrol is maintained at a constant level. The petrol is pumped from the main tank to this chamber, the float rising as the petrol flows in until the desired level is reached, when the inlet closes. The carburettor is equipped with such devices as accelerating pumps and economizer valves, which automatically control the mixture ratio for efficient operation under varying conditions. Level-road driving at constant speed requires a lower ratio of petrol to air than that needed for climbing hills, for acceleration, or for starting the engine in cold weather. When a mixture extremely rich in petrol is necessary, a valve known as the choke cuts down the air intake, permitting large quantities of unvaporized fuel to enter the cylinder.
