How a diesel engine works ENGLISH hd Transcript
00:22
In diesel engines the operating cycle starts
00:25
with clean air being drawn into the cylinder,
00:28
not a fuel - air mixture as in a conventional gasoline engine.
00:34
The motion of the piston compresses the air,
00:36
heating it to a high temperature.
00:40
When the piston nears the top of the cylinder,
00:42
fuel is injected under high-pressure
00:45
through a number of precisely machined holes
00:47
in the tip of the fuel injector.
00:51
The fuel enters the engine in the form of a fine spray
00:54
and the surface of each droplet quickly begins to vaporize
00:57
on its path through the hot air.
01:02
Spontaneous ignition takes place
01:04
without the need for a spark
01:05
and rapid expansion of the combusting mixture
01:08
increases the pressure in the cylinder,
01:10
forcing the piston down and powering the vehicle.
01:16
When the piston is close to its lowest position,
01:19
the exhaust valve starts to open and the exhaust stroke
01:22
then drives the spent gases out of the combustion chamber
01:25
and the cycle starts again.
01:30
In conventional gasoline engines, a mixture of fuel AND air
01:34
is drawn into the cylinder, compressed by the motion of the piston
01:37
and ignited by a spark as the piston nears the top of the cylinder.
01:43
The resulting combustion generates pressure
01:45
which forces the piston down to power the vehicle.
