Engine Detail
The TD-40's diesel engine was started on gasoline and then switched to diesel. The engine was manually cranked from the left side, which supplied fuel to a spark-ignition combustion chamber. Exhaust gas from this chamber was directed into the cylinders of the diesel. At 700 RPMs the gasoline chamber shut down and the engine ran as a true diesel., International Harvester, diesel, 4-cylinder, liquid-cooled vertical I-head, 460.7 ci [7.6 L]
