1
00:00:15,960 --> 00:00:19,450
Catalytic converters is one of
the most important technologies

2
00:00:19,450 --> 00:00:23,016
for pollution that has been
invented in over the last 50

3
00:00:23,016 --> 00:00:23,950
years.

4
00:00:23,950 --> 00:00:27,783
It's changed the game in terms
of what comes out of that car.

5
00:00:27,783 --> 00:00:28,916
Why does it work?

6
00:00:28,916 --> 00:00:30,550
It wouldn't work,
you wouldn't get rid

7
00:00:30,550 --> 00:00:33,333
of these things,
these toxic things,

8
00:00:33,333 --> 00:00:35,250
you wouldn't get rid of
them unless you ran it

9
00:00:35,250 --> 00:00:38,433
at 1,000 degrees and you're not
doing that underneath your car

10
00:00:38,433 --> 00:00:40,666
next to the gas tank.

11
00:00:40,666 --> 00:00:43,083
But if you put the
right catalyst in,

12
00:00:43,083 --> 00:00:46,200
all of those reactions to get
rid of those toxic chemicals

13
00:00:46,200 --> 00:00:48,783
can happen much more
quickly and efficiently.

14
00:00:48,783 --> 00:00:50,050
Right?

15
00:00:50,050 --> 00:00:50,683
OK.
