00:00:03,860 --> 00:00:05,340
Welcome to Power Onward,

2
00:00:05,660 --> 00:00:09,780
the podcast that pulls back the
current on the technologies, people,

3
00:00:09,880 --> 00:00:12,620
and partnerships shaping
the future of power.

4
00:00:13,680 --> 00:00:16,820
When firefighters respond to
a call, every second matters.

5
00:00:17,420 --> 00:00:20,480
And the trucks that carry them
can't hesitate, stall, or fail.

6
00:00:20,740 --> 00:00:24,840
Across North America, a large portion
of those trucks rely on Cummins engines,

7
00:00:24,940 --> 00:00:28,460
brakes, and drive trains to get crews
where they need to go. As you can imagine,

8
00:00:28,800 --> 00:00:31,100
fire and rescue can be extremely
demanding of its equipment.

9
00:00:31,300 --> 00:00:32,280
And for nearly a century,

10
00:00:32,660 --> 00:00:36,000
Cummins has been engineering dependable
solutions designed to protect property

11
00:00:36,120 --> 00:00:37,140
and life.
Today,

12
00:00:37,360 --> 00:00:40,720
we're exploring the powertrain
technologies firefighters
trust when the stakes

13
00:00:40,860 --> 00:00:43,800
are absolute. Hi, I'm Kim, global
brand manager here at Cummins.

14
00:00:44,000 --> 00:00:44,833
Hi, I'm Chris.

15
00:00:45,100 --> 00:00:48,600
I look after the engine business for
fire and emergency and recreational

16
00:00:48,620 --> 00:00:49,440
vehicles.

17
00:00:49,440 --> 00:00:53,040
All right. So Chris, I hear that
Cummins and fire service goes way back.

18
00:00:53,200 --> 00:00:54,940
Tell me more about Cummins,

19
00:00:55,360 --> 00:00:57,900
their role in maybe diesel
engines and fire apparatus,

20
00:00:58,000 --> 00:00:59,960
and what else you can
tell me about that legacy.

21
00:01:00,560 --> 00:01:04,900
Yeah, so almost a hundred years,
right? Beginning with the 1937 Stutz,

22
00:01:05,480 --> 00:01:08,720
the first diesel powered fire
truck. It still lives in Columbus,

23
00:01:08,780 --> 00:01:10,000
Indiana in station two.

24
00:01:10,660 --> 00:01:15,540
What was unique to that was 150
horsepower, 500 pound feet of torque,

25
00:01:15,620 --> 00:01:19,780
which by today's standards would
not measure up, but then it did.

26
00:01:19,880 --> 00:01:21,080
It was a step up.

27
00:01:21,420 --> 00:01:24,920
It was a step up in not
just the equipment, but also
the overall reliability,

28
00:01:25,120 --> 00:01:25,440
right?

29
00:01:25,440 --> 00:01:26,273
Exactly.

30
00:01:27,360 --> 00:01:31,960
So that engine was actually
in service from 1939 to 1974,

31
00:01:32,360 --> 00:01:33,780
about 35 years.

32
00:01:34,200 --> 00:01:35,033
That same engine?

33
00:01:35,040 --> 00:01:38,580
Yes. Testament to dependability
and making active runs.

34
00:01:38,860 --> 00:01:39,600
Absolutely.

35
00:01:39,600 --> 00:01:44,020
So we're hearing reliability revolution
through a Cummins diesel engine inside

36
00:01:44,040 --> 00:01:47,720
of that 1937 studs with more
torque, better durability,

37
00:01:48,300 --> 00:01:49,160
and longer run times.

38
00:01:49,460 --> 00:01:49,780
Yes.

39
00:01:49,780 --> 00:01:51,560
That's triple wins. We love to hear that.

40
00:01:51,820 --> 00:01:54,720
But I think that even
for me and for others,

41
00:01:54,840 --> 00:01:58,440
when we see a fire apparatus or a
firetruck, we simply see a vehicle.

42
00:01:58,900 --> 00:02:02,760
But there's a lot more that goes into
that because recently I heard them

43
00:02:02,820 --> 00:02:04,600
referred to as mobile power plants.

44
00:02:04,720 --> 00:02:07,440
Does that have to do with that duty
cycle once the engines hit the scene?

45
00:02:07,740 --> 00:02:09,900
So it can be central
to the whole operation.

46
00:02:10,000 --> 00:02:13,140
So they don't just go to pump
water. They have a lot of tasks.

47
00:02:13,200 --> 00:02:17,540
About 70% of their runs are
EMS, emergency medical service.

48
00:02:17,820 --> 00:02:20,860
So sort of like an ambulance. Most
of them are trained as paramedics.

49
00:02:21,280 --> 00:02:24,360
So not only that, but sometimes
they need to get up high, right?

50
00:02:24,420 --> 00:02:27,460
So they have aerials,
so platforms or ladders,

51
00:02:27,800 --> 00:02:29,520
so they can get to tall places,

52
00:02:29,580 --> 00:02:32,600
whether it's fighting fires or getting
to people that need their help.

53
00:02:32,760 --> 00:02:34,480
They also block traffic, right?

54
00:02:34,560 --> 00:02:38,040
So many of us have experienced that on
the interstate where you want something

55
00:02:38,120 --> 00:02:42,400
large in front of your rescue workers
to prevent danger to those that are

56
00:02:42,460 --> 00:02:43,293
serving others.

57
00:02:43,460 --> 00:02:44,880
So they have a lot of jobs.

58
00:02:44,940 --> 00:02:45,320
They do.

59
00:02:45,320 --> 00:02:48,020
The firefighters in the building doing
their thing, but the truck itself,

60
00:02:48,080 --> 00:02:50,840
the apparatus itself, is running
multiple tasks simultaneously.

61
00:02:51,160 --> 00:02:55,700
Absolutely. In addition, they
also with radio communications,

62
00:02:56,020 --> 00:02:59,500
comfort station. So this truck
serves a lot of purpose. In fact,

63
00:02:59,560 --> 00:03:02,200
about 70% of the time,
they are just idling.

64
00:03:02,540 --> 00:03:03,120
70%.

65
00:03:03,120 --> 00:03:07,680
About 70% of the time, about 25% of
the time driving and about 5% pumping.

66
00:03:08,000 --> 00:03:11,040
So that's sort of a standard
duty cycle for the truck.

67
00:03:11,140 --> 00:03:11,840
I know. I like that.

68
00:03:11,840 --> 00:03:15,160
I just visualize a pie chart as you were
breaking that down. All right, Chris,

69
00:03:15,220 --> 00:03:17,120
let's get into the components
of a fire apparatus.

70
00:03:17,560 --> 00:03:20,540
Why is each component so
essential for emergency responses?

71
00:03:20,960 --> 00:03:23,920
So Cummins has worked with the
fire service for many years.

72
00:03:23,980 --> 00:03:28,340
We've sold about 50,000 of
these over the last 25 years.

73
00:03:28,780 --> 00:03:33,760
So we work very closely to upgrade and
understand the needs of the fire service.

74
00:03:34,300 --> 00:03:35,780
So as an example,

75
00:03:36,060 --> 00:03:39,560
these engines are uniquely
created for the fire service.

76
00:03:39,960 --> 00:03:42,780
So not only are they restricted ratings,

77
00:03:42,840 --> 00:03:47,520
meaning we maximize the horsepower and
torque over a standard over the road

78
00:03:47,640 --> 00:03:51,420
truck engine. They do not D-rate
for emissions related faults.

79
00:03:51,540 --> 00:03:56,320
There is no SCR inducement all in the
name of getting the truck to the scene.

80
00:03:56,500 --> 00:03:58,900
But as important as getting
to the scene quickly,

81
00:03:59,800 --> 00:04:02,220
stopping the truck is also important.

82
00:04:02,340 --> 00:04:07,040
So we have compression brakes that
are anywhere from 350 horsepower up to

83
00:04:07,380 --> 00:04:10,220
600 horsepower to slow
the vehicle quickly.

84
00:04:10,380 --> 00:04:12,700
Right, because I'm sure
that's a lot of equipment.

85
00:04:13,040 --> 00:04:16,340
The vehicle itself is quite heavy and
you need to stop on a dime, so to speak.

86
00:04:16,820 --> 00:04:20,000
Right. And that's on top of
the Meritor drive train, right?

87
00:04:20,320 --> 00:04:22,260
Which also has very strong braking.

88
00:04:22,500 --> 00:04:24,720
Are there any new innovations
within the powertrain?

89
00:04:24,960 --> 00:04:29,540
There sure are. So we'll be releasing
the Meritor QuickDisc systema.

90
00:04:30,380 --> 00:04:33,060
So not only does it provide
superior braking power,

91
00:04:33,260 --> 00:04:36,140
but the main thing is it makes
maintenance so much easier.

92
00:04:36,300 --> 00:04:39,960
You no longer have to pull the wheel
end off in order to change the rotor.

93
00:04:40,280 --> 00:04:41,360
This will save time.

94
00:04:41,740 --> 00:04:45,080
It will improve repair quality
within the maintenance organization.

95
00:04:45,420 --> 00:04:47,920
So it's a pretty cool innovation.

96
00:04:47,980 --> 00:04:51,460
That's a massive win for our customers
and for our teams on the ground doing

97
00:04:51,520 --> 00:04:55,740
those repairs. So we have this massive
80,000 pound mobile power plant.

98
00:04:56,200 --> 00:04:58,400
It's got to perform perfectly
in extreme conditions,

99
00:04:58,920 --> 00:05:02,920
meet strict standards when it comes to
emissions, and then be easy to maintain.

100
00:05:03,240 --> 00:05:05,860
How is Cummins innovating to
deliver this to customers?

101
00:05:06,300 --> 00:05:09,900
So maybe the biggest news is
for 2027, the NOX emissions,

102
00:05:10,020 --> 00:05:12,400
oxides of nitrogen drop another 80%.

103
00:05:13,100 --> 00:05:17,160
So over the last 25 years,
they were reduced by about 80%.

104
00:05:17,640 --> 00:05:21,240
Now we're doing that in three or four
years. So people ask how we do that.

105
00:05:21,440 --> 00:05:22,580
It's a lot of technology.

106
00:05:23,120 --> 00:05:28,100
So probably the biggest thing is we
have heaters at the inlets to both

107
00:05:28,180 --> 00:05:31,660
of the after treatment components,
the diesel particulate filter,

108
00:05:31,980 --> 00:05:33,120
the SCR catalyst,

109
00:05:33,480 --> 00:05:37,400
and that requires a 48 volt alternator
on the engine to drive those.

110
00:05:38,040 --> 00:05:41,250
So that's the majority
of our NOx reduction.

111
00:05:41,610 --> 00:05:46,450
There are also clean sheet design.
So both the X10 and X15 are new

112
00:05:46,510 --> 00:05:50,370
from the ground up, optimized based
on our experience with the X12,

113
00:05:50,870 --> 00:05:55,810
which was largely successful. So
the engine has gotten a lot cleaner.

114
00:05:56,150 --> 00:05:58,750
In addition, we've done a lot
of things for reliability.

115
00:05:59,150 --> 00:06:01,630
So now you'll find that
both of those engines,

116
00:06:01,690 --> 00:06:06,390
the X10 and X15 have a dual overhead cam.
They also have a rear gear

117
00:06:06,450 --> 00:06:11,430
train. So this just makes the engine
structure stronger to reduce leaks,

118
00:06:12,150 --> 00:06:17,150
keep vehicles in service. Another thing
would be the quick disk braking system,

119
00:06:17,250 --> 00:06:18,990
so disk brake for the rear axle.

120
00:06:19,550 --> 00:06:23,250
The big innovation there is the fact that
you can pull the rotor without having

121
00:06:23,310 --> 00:06:24,590
to disturb the wheel end.

122
00:06:24,960 --> 00:06:29,110
So not only does that give
us a faster service event,

123
00:06:29,170 --> 00:06:31,400
but it also improves the repair quality.

124
00:06:31,950 --> 00:06:34,290
Brilliant. A win-win overall
for all teams involved.

125
00:06:34,450 --> 00:06:37,230
What I'm hearing is that the fire
service doesn't just buy equipment.

126
00:06:37,610 --> 00:06:38,670
They rely on partners.

127
00:06:39,110 --> 00:06:41,950
So how is Cummins showing up for the
fire service beyond the engine and

128
00:06:41,990 --> 00:06:42,823
components?

129
00:06:42,890 --> 00:06:47,070
Yeah, it's truly a team effort. So we
start by working with a chassis builder,

130
00:06:48,490 --> 00:06:50,130
either it's custom or commercial.

131
00:06:51,170 --> 00:06:55,550
So we work with them to ensure that the
installation quality requirements are

132
00:06:55,570 --> 00:06:56,403
met.

133
00:06:56,850 --> 00:07:01,430
It then goes to a bodybuilder where
they're putting on all the compartments on

134
00:07:01,450 --> 00:07:02,930
the back and putting that together.

135
00:07:03,010 --> 00:07:06,990
We also work with them to help them with
programming and those types of things.

136
00:07:07,190 --> 00:07:08,040
Once it gets into ...

137
00:07:08,190 --> 00:07:12,870
We also count on a dealer network
that looks after these vehicles

138
00:07:13,070 --> 00:07:14,630
and our distribution systems.

139
00:07:14,690 --> 00:07:19,290
So Cummins has about 3,500
locations that can sell parts for

140
00:07:19,370 --> 00:07:20,210
automotive engines.

141
00:07:20,430 --> 00:07:25,120
And we have over 2,000 locations that
can do warranty service on these.

142
00:07:25,320 --> 00:07:26,520
And this is in North America or-.

143
00:07:27,230 --> 00:07:30,240
This is in North America.
Wow. 2000 in North America.

144
00:07:30,560 --> 00:07:33,800
And that's the majority of our
business. When we get overseas,

145
00:07:34,200 --> 00:07:35,840
the types of apparatus vary.

146
00:07:37,010 --> 00:07:37,560
That totally makes sense.

147
00:07:37,560 --> 00:07:42,280
The other thing I would add is we're
looking at new solutions that also keep

148
00:07:42,360 --> 00:07:46,320
equipment and service less trips
to the shop. So for example,

149
00:07:46,880 --> 00:07:50,040
Cummins Acumen is a
telematics system. Basically,

150
00:07:50,200 --> 00:07:54,960
that means it's communicating
information from the engine back to us

151
00:07:55,800 --> 00:07:57,800
so that we can provide repair guidance.

152
00:07:58,360 --> 00:08:02,040
We can also do things over time
to do over the air calibrations.

153
00:08:02,680 --> 00:08:04,670
We can do remote diagnostics.

154
00:08:04,970 --> 00:08:08,840
So these are all huge things to keep
the vehicle in the station and not in a

155
00:08:08,880 --> 00:08:09,640
repair shop.

156
00:08:09,640 --> 00:08:10,040
Exactly.

157
00:08:10,040 --> 00:08:13,000
It's nice that we'll have a pulse on
things so we're not always being reactive

158
00:08:13,080 --> 00:08:14,320
when the customers come to us.

159
00:08:14,720 --> 00:08:17,800
It's like we've got to pull so we can be
proactive and just make sure that they

160
00:08:17,920 --> 00:08:20,560
don't have to be in there as
often, as frequently or as long.

161
00:08:20,840 --> 00:08:21,520
Exactly.

162
00:08:21,520 --> 00:08:25,040
Do you have any firefighter testimonials
based on what you've just said?

163
00:08:25,720 --> 00:08:28,120
It's always fun to go to trade shows.

164
00:08:28,280 --> 00:08:32,880
So whether it's FDIC or the
Lancaster County Fireman's

165
00:08:32,960 --> 00:08:36,200
Association Fire Expo,
hear a lot of stories.

166
00:08:36,440 --> 00:08:40,230
So a lot of firefighters are
amazed at the performance.

167
00:08:40,290 --> 00:08:42,030
So some say that there
shouldn't be a throttle pedal.

168
00:08:42,760 --> 00:08:46,090
It should just be an on/off switch
to accelerate as quickly as they can,

169
00:08:46,150 --> 00:08:50,170
but we hear a lot of positive comments,
especially around the performance.

170
00:08:50,270 --> 00:08:53,070
It's a testament to all the hard work
that goes into each of these products,

171
00:08:53,130 --> 00:08:53,450
right?

172
00:08:53,450 --> 00:08:54,283
Exactly.

173
00:08:54,290 --> 00:08:56,430
When you look at the next
generation of fire apparatus,

174
00:08:56,770 --> 00:08:58,970
what excites you the most about
where the technology is headed?

175
00:08:59,410 --> 00:09:01,030
It's really pretty exciting.

176
00:09:01,250 --> 00:09:05,430
I think we will continue to
see some benefits from AI,

177
00:09:05,890 --> 00:09:10,110
not only from a design perspective so
that we can optimize designs like we have

178
00:09:10,150 --> 00:09:11,370
with the X10 and X15,

179
00:09:12,390 --> 00:09:16,450
but also on how we monitor the
performance of those engines.

180
00:09:16,890 --> 00:09:18,210
Where have we had issues?

181
00:09:18,610 --> 00:09:23,170
We use our warranty data and we can
fold all of that into the new designs to

182
00:09:23,270 --> 00:09:24,750
make an even better engine.

183
00:09:24,930 --> 00:09:26,010
That is a recurring theme.

184
00:09:26,170 --> 00:09:30,130
AI just amplifying all of our efforts and
being able to get things to the market

185
00:09:30,190 --> 00:09:31,050
faster, essentially.

186
00:09:31,410 --> 00:09:35,010
If someone remembers one
thing about Cummins and fire
service after listening to

187
00:09:35,050 --> 00:09:36,790
this episode, what
would you want it to be?

188
00:09:37,370 --> 00:09:41,050
We want to build great products,
but we also want to support.

189
00:09:41,330 --> 00:09:45,650
So it's really important to us why we've
worked to develop so many dealers and

190
00:09:45,830 --> 00:09:49,870
our Cummins branches to be able
to support the fire service.

191
00:09:50,370 --> 00:09:51,610
So support is everything.

192
00:09:52,030 --> 00:09:53,550
Chris, thank you so much
for your time today.

193
00:09:53,790 --> 00:09:57,550
It's really cool to see what keeps those
trucks so dependable because for us,

194
00:09:57,610 --> 00:09:59,130
dependability isn't just important.

195
00:09:59,430 --> 00:10:02,350
It's essential and especially
for the fire service. All right,

196
00:10:02,450 --> 00:10:05,710
so what's the big idea for this episode?
When we talk about fire and rescue,

197
00:10:06,050 --> 00:10:08,050
we often think about the
sirens and the Chrome,

198
00:10:08,330 --> 00:10:10,970
but the real story is about
readiness and reliability.

199
00:10:11,250 --> 00:10:15,210
We've seen that today for Cummins. A
firetruck isn't simply just a vehicle.

200
00:10:15,650 --> 00:10:19,350
It's a rescue apparatus that firefighters
rely on during the worst day of

201
00:10:19,390 --> 00:10:22,190
people's lives. In an industry
where every second matters,

202
00:10:22,350 --> 00:10:23,970
Cummins isn't just an engine builder.

203
00:10:24,210 --> 00:10:27,850
We're providing confidence and reliability
so real heroes can get where they're

204
00:10:27,890 --> 00:10:30,890
needed safely and fast.
When lives are on the line,

205
00:10:31,450 --> 00:10:34,590
dependability isn't just a
technical spec. It's a promise.

206
00:10:35,170 --> 00:10:39,050
