Cummins Diesel Engine Running in a Thomas School Bus
This Thomas [pusher] School Bus is powered by a Cummins "C" Model Diesel Engine. The displacement is 8.3 Litres with a inline 6 cylinder configuration. The fuel injection system is run by a Bosch injection pump with fuel nozzles installed in each cylinder. You can see the accessability at the front of the engine which houses the timing gears making engine disassembly [camshaft] a snap. The water pump is belt driven running just below the alternator. The cylinder liners are removable making engine repair very cost effective since everything can be done in the frame, hence the term [in-frame] This Diesel is very dependable with a 250 hp rating and well suited for medium duty use.
