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. 

Reduce Costs by Choosing Clean-Diesel Over Alternative Fuels

It's an ongoing debate: which fuel type provides the lowest total cost of ownership (TCO) to school bus fleets. Opinions abound on all sides of the matter. A gasoline-powered bus has a low initial purchase price, so it must have the lowest TCO. Propane fuel costs much less than clean-diesel, so a propane-powered bus must have the lowest total cost of ownership. And compressed natural gas (CNG) buses have a high initial purchase price, but advocates contend that after the initial cost is recouped, the savings on CNG fuel contribute to a low total cost of ownership. 

Think You Know Diesel? Think Again

New federal emissions standards ratings released this year for school bus engines reveal that all fuels, including diesel, are now much cleaner with emissions falling well below EPA emissions standards.

EPA Accepting Applications for School Bus Rebate Program

The U.S. EPA announced school districts, school bus contractors, state and local governments, and tribal governments can now apply for their share of an expected $7.25 million to replace older diesel school buses or for retrofit projects.
