Collaborating with customers for better performance
Since 2004, Cummins has collaborated with its end user truck fleet customers
on 57 customer-focused Six Sigma projects, which saved 49 million gallons of fuel
and avoided 495,000 tons of CO 2
emissions. That’s equivalent to taking 95,000 cars
off the road.
Greater fuel economy:
driver assist
PowerSpec
This tool helps customers specify
the correct vehicle and electronic
parameters using inputs such as
gross vehicle weight, terrain, and
engine type to determine proper
axle and transmission configuration.
Reduced vehicle speed saves
fuel. Road Speed and Cruise
Control Governors limit the
maximum vehicle speed while
Smart Torque allows high
torque in the top two gears,
minimizing the number of
down shifts required to
maintain speed.
Greater fuel economy:
engine fine-tuning
Fuel economy reference library
Customers have access to
information resources describing the
best fuel economy configuration for
electronic parameters, transmission,
tires, axle ratio and other settings.
Fleet management
In addition to “active” features,
Cummins engines also have
a number of “information
features” where “trip” or
“duty cycle” information is
stored. Fleet managers can
analyze data for variations
between drivers or trucks,
look for trends and use the
data for driver coaching.
Customers achieve greater
fuel economy through
optimization of duty cycles,
calibration and hardware as
well as Cummins’ help with
transmission integration,
accessory management
and down speeding.
