We at Blue Bird are proud to offer Cummins engines in our diesel
and CNG bus offerings. Cummins prides itself in offering the cleanest and most
reliable engines in North America, along with fantastic fuel economy. These
engines are built to give prolonged engine life along with one of the best
engine-parts warranties in the business.
Introducing the Cummins ISV5.0!
The Cummins ISV5.0 V8 diesel significantly reduces your cost of operation, achieving leading urban fuel economy. The ISV5.0 combines the latest in Cummins combustion technology, with advanced weight-saving components that include a compacted graphite iron (CGI) block, and high-strength aluminum alloy head and composite valve covers. The high power-to-weight ratio of the ISV5.0 helps you get the most out of every gallon of fuel.
This clean diesel engine is used in our
All American and Vision diesel bus models. This engine helps reduce fuel
expenses as well as greenhouse gases (GHG). The fuel economy for the 2013
ISB6.7 engine is up 2% versus their 2010 models, due to the addition of an air
intake throttle, which makes their EGR system more efficient. This results in
increased fuel economy, lowers operating costs, and provides a cleaner
environment with a reduction in the use of diesel fuel.
Utilized by our All American CNG
model, the ISL G engine operates on clean, domestically produced compressed
natural gas. The 2013 ISL G engine has improved fuel economy over the 2010
model due to the VGT Turbocharger being modified for greater efficiency. As a
result of this engine taking advantage of an abundance of domestically
produced natural gas, fuel prices are also lower.
Exceeds EPA & DOT Regulations
Cummins engines will meet 2014
Environmental Protection Agency (EPA) and United States Department of
Transportation (DOT) regulations for fuel economy and greenhouse gas reduction

designs, develops and supports virtually every component from air handling
to exhaust aftertreatment as a totally integrated system. This allows
Cummins to optimize every function, better than other engine manufacturers.
Their proven Cummins Aftertreatment System on both the ISB6.7 and the ISV5.0
use a Diesel Particulate Filter (DPF) and Selective Catalytics Reduction
(SCR) technology, all managed to maximize efficiency and lower emissions.
It virtually eliminates NOx through the injection of a small amount of
Diesel Exhaust Fluid (DEF) upstream of the catalyst. In 2013, On-Board
Diagnostics are being added to continuously monitor the performance of the
emissions system, which will alert the driver when it needs troubleshooting
and possible repair. This On-Board Diagnostics system has already been
proven in thousands of on-road vehicles since 2007.
Cummins engines feature the most comprehensive base
warranty in the industry, with 5 years or 100,000 miles of coverage
(whichever occurs first), and their new extended coverage plans offer up to
10 years of coverage. This is evidence of Cummins' complete confidence in
their engine's robust design, quality manufacturing, and long-term
