Customer Profile:
Pierce Transit
• Transit agency for
Tacoma/Pierce County,
WA
• Total fleet: 235 buses
• Purchased 38 C Gas
Plus-powered 40’, lowfloor buses in 2002
• 100% natural gas fleet by
2005
“The C Gas Plus is head-and-shoulders
above the other natural gas engines in our
fleet.”
“Reliability of the natural gas vehicles is
very much comparable, and in many
cases, better than their diesel
counterparts”

2007 ISL G Features
• Stoichiometric EGR
– Uses high EGR rates in
combustion process in place of
excess air (Lean Burn).
• Oxygen free exhaust
– allows for the use of a three way
catalyst
• Three Way Catalyst
• Exhaust Aftertreatment
– simple passive device, highly
effective hydrocarbon, CO, and
NOx control.
– Maintenance Free
• Improved torque throughout
operating range
• New Electronic Control Module
– provides full monitoring and
control of engine sensors, fuel
system and ignition system
• Cummins Cooled EGR
– lowers in cylinder temperature
and reduces oxygen
concentration
• Low installed weight
– (1570 lb wet)
• Highest power to weight ratio
in its class
2007 ISL G – Key Benefits
• Shared block and components with
2007 ISL diesel
– Over 80% parts commonality
• 5% efficiency Improvement Target
– Lean Burn vs. Stoich EGR
combustion.
• 34% more clutch engagement
torque
– Better performance
• Transit 280 hp rating torque
improved to 900 lb-ft (+6%)
• Rated speed 2200 rpm
– (same as diesel)
OEM Availability
• Working with all traditional OEM’s on the transition
from C Plus and L Plus engines.
• Transit and Refuse OEM’s have pre production
engines for installation engineering
– 280, 300, 320 ratings
– Follows the engineering of the ISL diesel
– Similar packaging and cooling requirements
• 6 cylinder, cooled EGR, air to air aftercooling
• Commercial availability – June 1, 2007
