What engine does a school bus have?

Answer 1

Really depends on the type. A Type A school bus might have a gas, diesel, or CNG engine.. those will use whatever is standard for the chassis manufacturer (e.g., Triton gas or Powerstroke diesel for Ford chassis, Vortec gas or Duramax diesel for General Motors chassis, Hemi gas or Cummins diesel for Dodge chassis). For Type B, C, and D buses, Thomas Built buses is owned by Daimler A.G. - the parent company of Freightliner, Western Star, and Mercedes Benz, and have been available with Cummins, Mercedes-Benz, or Caterpillar (until 2009) diesel engines or Cummins CNG engines.

IC Bus is a subsidiary of Navistar International, and can have Navistar MaxxForce or Cummins diesel engines, or Cummins CNG engines.

Blue Bird does not make their own engines, so they will use Cummins diesel or CNG engines.

In the case of diesels, 6 - 7 liters is most likely what you'll find, though I have, in the past, seen school buses with 7.3 liter 3126 and C7 Caterpillars.
