    At the 2016 STN Expo in Reno, Nevada, Blue Bird unveiled a number of significant changes to its Vision product line.  As the Vision saw exterior updates less than two years ago, nearly all of the revisions were made under the hood.  Alongside the introduction of the gasoline-fueled Vision, Blue Bird has introduced a total of three new engines for the bus in 2016.
    For the first time since the end of Caterpillar engine production after 2009, there will again be two diesel engine options produced for the Vision.  Alongside the Cummins ISB6.7, Cummins is introducing its 5.0L ISV5.0 V8 diesel for the Vision.  Depending on specification, the engine produces 200-275hp.  The ISV marks the return of a V8 diesel engine to a full-size Blue Bird for the first time since the 2008 discontinuation of the Blue Bird/International SBCV.       
    Since its introduction in 2012, ROUSH CleanTech has produced over 7500 Blue Bird Visions with its propane fuel system, featuring the Ford 6.8L V10 and 6-speed automatic transmission.  Using the same engine as a platform, Blue Bird and ROUSH CleanTech have developed two new fuel systems for the V10 engine.  Earlier this year, Blue Bird unveiled the gasoline-fueled version of the Vision.  At the STN Expo, the company unveiled the Blue Bird Vision with the engine powered by compressed natural gas (CNG), with deliveries to begin by the end of 2016.  While becoming the second CNG-fueled Type C school bus entering production (following the Thomas Saf-T-Liner C2 CNG), all three alternative-fuel versions of the Blue Bird Visions utilize the same engine.
    To further improve its propane-fueled variant, Blue Bird and ROUSH CleanTech introduced its fourth-generation propane system for the Vision.  Building on the extended-range tanks previously introduced, the newest-generation system featured changes to optimize reliability and improve engine starting.
    Discussion:
    What do you think of these revisions to the Blue Bird Vision product line for 2017? 
    If you were lucky to attend the STN Expo to see these buses running in person, what are your thoughts?

    Will it run on diesel, propane, or 87-octane?  If the bus is an IC CE-Series, the latter may be added to the list in the near future.  At the 2016 School Transportation News (STN) Expo Conference and Trade Show in Reno, Nevada, IC Bus debuted its first gasoline-powered full-size school bus for the purpose of evaluation and test drives by show attendees.  Although its official production date has yet to be announced, the vehicle marks the return of gasoline power to an International-chassis school bus for the first time since the end of 1986 production.
    Why the return to gasoline-engine vehicles?  For many that have been on a school bus in the past 25 years (as either a rider or driver), the engine under the hood has likely been a diesel-powered unit (in Type D buses, inside the engine compartment instead of under the hood).  During the mid to late 1980s, diesel engines went from being higher-power options alongside gasoline engines to the primary type of engines used in full-size school buses.  As concerns remained over the stability of fuel prices in the 1980s, the higher comparable fuel economy of many diesel powerplants became a favorable attribute; "passing everything but the gas station" was not considered high performance for a school bus.
    During the late 2000s, clean-air regulations for diesel engines have become significantly more stringent.  To remain compliant and to allow for the continued sale of diesel engines in school buses (and all large trucks), engineering controls have been developed, at the expense of increased complexity, reduced reliability, fuel economy, and overall performance.  While alternative-fuel vehicles (in the school bus segment, propane/LPG and CNG) offer a "clean-air" solution and eliminate a number of performance drawbacks, potential buyers often walk away from the higher initial purchase price and the separate issue tied in with fueling infrastructure.
    Three decades after diesel overtook gasoline as the powerplant of choice, the landscape is changing again.  While over 90% of full-size school buses remain powered by diesel engines (the rest by propane and CNG), manufacturer IC Bus predicts a significant transition, with market share of diesel changing from the current approximate 92% to a figure closer to 60-65% by 2020. .tg {border-collapse:collapse;border-spacing:0;margin:0px auto;} .tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;} .tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;} .tg .tg-s6z2{text-align:center} .tg .tg-baqh{text-align:center;vertical-align:top} .tg .tg-amwm{font-weight:bold;text-align:center;vertical-align:top} .tg .tg-yw4l{vertical-align:top}
    Market Share Fuel Type (by year) 2016 2020 Diesel 92% 60-65% Alternative(Propane/CNG), Gasoline 8% 35-40% According to the engine manufacturer, gasoline will end up up serving as a "third alternative fuel", along propane/LPG and CNG.  Although it is also a fossil fuel alongside diesel, gasoline engines in medium-duty applications work with improved cold-weather starting.  In addition, the emissions treatment systems used for gasoline engines are far more stable than the emissions systems in use on diesel engines.  In stark constrast to propane and CNG powerplants, infrastructure is not an issue tied to gasoline; it is virtually impossible to find a filling station in North America that does NOT carry unleaded gasoline.
    The big question: what will be under the hood of the gasoline-fuel bus?  To save money and time over developing its own medium-duty truck engine (the last family of International Harvester engines used in school buses was first developed in 1959), Navistar outsourced the engine production for the gasoline IC CE-Series to Illinois-based Power Solutions International (PSI).  A designer and manufacturer of engines for clean-air/alternative-fuel systems, PSI has worked with the company in the engine supply for the propane version of the CE-Series.
    Using the same 8.8L V8 engine as before, PSI will be supplying the bus with a gasoline fuel system.  Rated at 265hp @2800RPM and 545 lb-ft/torque @1800RPM, the PSI V8 engine produces similar horsepower and torque output as the Cummins ISB6.7L diesel (depending on specification).  Along with the improved cold-start performance in the gasoline unit, IC Bus and PSI describe the primary difference between the gas and diesel engines as the lack of vibration and noise when running.

    What do you think of the gasoline-engined IC CE-Series?  If you were lucky enough to visit the STN Expo, did you have a chance to see (or drive?) this new vehicle?
    Do you think gasoline will be a "third alternative fuel" to diesel?

    According to School Transportation News, IC Bus announced this week that the company will begin to offer Cummins diesel engines on their RE-Series Type D product line.  As the RE is one of the very last Navistar products to use the long-running International DT engine family, this will match its powertrains with that of the CE-Series, which adopted Cummins engines during its 2015 production.
    IC Bus will introduce two newly redesigned medium-duty diesel engines for the RE-Series.  In 2017, the RE will become available with the Cummins L9 (which will replace the current Cummins ISL9 ), followed by the B6.7 (which replaces the ISB6.7) in 2018. 
    In the school bus industry, the ISL9 is in use by both the Blue Bird All American Rear Engine and Thomas Built Buses HDX while the ISB6.7 is used in a number of Type C and Type D school buses.

    Although output for school bus configurations of the L9 have not been announced, the ISL 9 currently is sold in outputs ranging from 260hp to 300hp as it is sold in the Blue Bird All American Rear Engine and Thomas Built Buses HDX.

    For nearly all school districts across North America, the 2015-2016 school year has come to its conclusion.  For those who drive the 485,000 school buses of the United States (and those who support them), there are two things that the School Bus Web team wants to say.  One of them is thank you for keeping everyone on the buses safe along with those sharing the road with the bus fleet.  Along the subject of safety, we are interested in finding out how safe things have turned out for each operation this year, small or large.
    Even if the school year was accident-free, there may have been many challenges to an operation doing so successfully.  While there are threats to safety every day outside (or inside) of the bus, there are also other types of challenges for some operations.  In addition with the accommodation of the needs of many different students, the challenges of student behavior, the complexity of new equipment, the issue of money can threaten the very existence for some transportation operations.
     What do you think was your biggest challenge for 2015-2016?

    Nowadays, clean emissions are a hot topic in popular culture. Auto manufacturers around the globe have begun to produce clean hybrid and plug-in electric vehicles, politicians have passed bills and regulations to expedite the move to renewable energy sources, and activists have made their voices heard.
    California was one of the first states to jump on the clean energy bandwagon, with a 14% decrease of CO2 emissions in the 2000-2013 Greenhouse Gas reporting period. The main force behind this change is the California Air Resources Board, or CARB for short. CARB was formed in 1967 under the supervision of then-governor Ronald Reagan to combat smog and air sanitation issues. CARB has since adapted to modern trends in air quality such as regulation of industrial and transportation emissions.
    In 2008, when CARB passed a bill regulating the emissions of diesel particulates from all diesel-powered vehicles in California, the school transportation industry began to look at potential options to comply with these new regulations, as public school districts were also required to comply with CARB's new standards. It was decided that the only options were to retrofit non-compliant buses with Diesel Particulate Filters (DPFs) to filter out the diesel particulates, replace the engines with newer compliant ones, or replace the non-compliant buses altogether.
    School districts all across California took different approaches to this; with the largest districts such as Los Angeles Unified School District launching an initiative to replace large chunks of their fleet with green natural gas powered vehicles, while smaller districts opted for DPF retrofits. It may seem apparent that DPF retrofits would be the best option in this case, however, the cost of DPFs plus installation fees required a large sum of money to be taken out of district budgets. Additionally, due to the nature of older two-stroke diesel engines, a large number of buses in California's aging fleets could not be retrofitted with particulate filters.
    This inability to retrofit older buses posed the biggest threat to school districts. With some school buses in California approaching 20 to 30 years in age, a very significant amount of school buses would have to be replaced.
    For districts with older fleets, the only option has been to replace their existing fleet with a new, compliant one. In 2015, hundreds of districts utilized grant money to cover a part of the cost of new buses. However, this grant money did not cover the entire cost of new buses, which meant the remainder would have to be taken out of school district budgets.
    In a hearing in Redding, CA last January, a number of transportation officials testified against CARB's actions. Among them, Tom Carroll, Director of Transportation for Shasta Union High School District discussed how CARB's regulations have affected student transportation in his district. He stated that he has had to retrofit 22 of the school buses in his fleet as a result of CARB's mandates. "We consistently have problems on a daily basis, if not multiple times per day" stated Carroll, referring to the buses that have been retrofitted. Since Diesel Particulate Filters first hit the market in the mid-1980's, they have been known to cause issues due to particulates building up and blocking the flow of exhaust.
    Carroll also discussed the impact on his departments budget. "Any increases we see with the ARB regulations that causes higher maintenance costs; that's money that we siphon off from the children", referring to the amount of money pulled from district education budgets to fund the ARB-mandated retrofits. "It makes it difficult. It makes it more expensive."

    Have you ever thought about what happens to school buses after they outlive their purpose of transporting students? With many older school buses being retired each year, this brings up some interesting thoughts. At School Bus Web, we are showcasing interesting school buses that have been repurposed over the years.
    Just outside of the historic town of Coloma where gold was first discovered in California resides a large number of rafting establishments that serve the American River, particularly in the summer. These rafting companies have repurposed many different vehicles to transport rafters back up to the camps after their adventure, but Mother Lode River Center's fleet in particular stands out. Alongside a 1970's Superior Pioneer on an International Harvester Loadstar chassis, the river center operates a former Los Angeles Unified School District 1987 Gillig Phantom School Bus with a modified Detroit Diesel 6V92TA engine fueled by vegetable oil. Not only does it reduce emissions by transporting large amounts of people, but it also relieves local restaurants of their waste vegetable oil.
