Diesel is the predominant know-how in industrial trucking, faculty, and transit bus sectors, in accordance to the Diesel Expertise Discussion board’s evaluation of information sourced from S&P World Mobility TIPNet information of automobiles in operation for Class 3-8 as of December 2021.
This evaluation discovered the next:
Industrial Vans: 76% of the roughly 15 million industrial vehicles (Class 3-8) that make up the nation’s fleet run on diesel. Of these, the most recent era of superior diesel know-how fashions now account for 53% of that fleet.
Different fuels that play a job in industrial trucking embody gasoline (23%) and compressed pure fuel (0.4%). Electrical and different classes every register lower than 1%.
Of the biggest vehicles (Class 8) in operation, 97% are diesels. About 32% of all electrical vehicles nationwide are in California, the place for each electrical truck there are about 300 diesel vehicles (all years, Courses 3-8). Nationwide, for each electrical industrial truck in operation, there are 995 vehicles powered by diesel.
Final yr, Indiana had the biggest variety of new-generation diesel vehicles registered (69.3%), adopted by Utah (63.2%), Pennsylvania (62.8%), Texas (60.1%), Oklahoma (60.0%), Florida (59.1%), the District of Columbia (58.4%), Illinois (56.2%), Maryland (55.7%), and Wisconsin (55.5%).
For the biggest industrial vehicles (Class 8), 62.5% of diesels on the street are 2007—that means they’re geared up with at the least a diesel particulate filter. For gasoline automobiles that make up a couple of quarter of all industrial vehicles (Class 3-8), greater than half (57.5%) of these in operation are 2007 and newer mannequin years.
The importance of the mannequin years (2007 and 2010 and later MY) pertains to emissions requirements and the introduction of latest emissions controls comparable to particulate filters, oxidation catalysts, and selective catalytic discount methods. This allows new diesel engines to realize near-zero emissions with growing gasoline effectivity and decrease carbon dioxide (CO2) emissions.
In earlier analysis commissioned for DTF, AutoForecast Options discovered that growing the variety of superior diesel know-how vehicles on the street will eradicate greater than 1.3 billion metric tons of CO2 throughout this decade.

Faculty Buses: 91% of the roughly 500,000 faculty buses run on diesel energy. Different fuels that play a job in pupil transportation embody gasoline (4%) and different fuels (5%). Electrical and compressed pure fuel every register lower than 1%.
Of the diesel portion of the present faculty bus fleet, roughly 72% of all buses in operation have at the least particulate entice know-how and 58% are of the most recent era of superior diesel know-how geared up with each particulate filters and selective catalytic discount methods.
Transit Buses: 79% of all non-school (transit) buses in operation are powered by diesel, 10% compressed pure fuel (CNG), electrical (6%), different (5%) and gasoline (0.1%). The “different” class contains hybrid diesel electrical in addition to propane-powered buses.
For the diesel portion of the present fleet, about 59% of transit buses are at the least geared up with particulate entice know-how and 47% are the most recent era of superior diesel know-how geared up with each particulate filters and selective catalytic discount methods.
New Jersey is the state that added essentially the most new-generation diesel buses in 2021 (greater than 300) in comparison with the earlier yr. Washington D.C. noticed a 15.3% enhance in variety of new diesel buses put in service (2021 vs. 2020).
The Diesel Expertise Discussion board is a not-for-profit group devoted to elevating consciousness concerning the present and future position of diesel engines, tools, and fuels. Discussion board members are leaders in superior diesel know-how, emissions controls, in addition to petroleum-based and renewable biofuels.
