There is More to School Bus Emissions than NOx

There is much debate about the cleanliness of school buses today, particularly surrounding diesel and propane engines. Both are touted as clean burning and emissions data being thrown around in the industry can make you dizzy and, quite frankly, confused. The truth is that, based on EPA-regulated emissions, clean-diesel school buses today are comparable to or cleaner than other fuel types like propane, CNG and gasoline.

ROUSH CleanTech Propane System Achieves HD-OBD Certification

Introducing the IC Bus, Gasoline Powered CE Series

IC Bus is now in production with the CE Series Gasoline Type C school bus. The CE Series with the PSI 8.8L gasoline engine is purpose built and designed for stop and start operation, featuring similar power and performance to diesel, which allows for immediate acceleration after stops and greater hill climbing capacity. “We know our customers want a choice in powertrain options and our new gasoline-powered bus will be just another example of how IC Bus is responding to market demand,” commented Trish Reed, vice president and GM of IC Bus.

Maintaining your Budget

As fleets look to buy new buses, many approach a bid with a concerted effort to get the cost of the individual buses down as much as possible. After all, who doesn’t like to walk away from a good deal? With most districts are concerned with the “here and now” of an annual budget, it is very easy to lose sight of the costs that are created over the life of the vehicle. School buses have an average life of 10-15 years. That’s a long time to consider not only fuel costs, but also the cost of maintaining the vehicle, and replacing necessary parts. 

The New Stay Warm Feature Improves Engine and DPF Performance for Thomas Built Buses

 

HIGH POINT, NC – In early 2017, Thomas Built Buses announced a revolutionary new feature for diesel engines: Diesel Particulate Filter (DPF) Temperature Stabilization, also known as the Stay Warm feature. This new feature optimizes the regenerative parameters of diesel engines, increasing active regeneration and decreasing aftertreatment DPF maintenance issues. Over the past year, Thomas Built dealers have been implementing the Stay Warm feature in diesel school buses across North America, and school districts could not be more pleased. 

Diesel and Propane and Gas, Oh My!

One of the most important decisions regarding a bus purchase is the type of fuel to choose. There is a lot of conflicting information out there today...those that say alternative fuels are not worth pursuing, or that diesel is going the way of the dinosaur. The fact of the matter is, each fleet may operate a different fuel type in order to achieve their best total cost of ownership, or TCO.
