The Hercules DFXE was an American diesel truck engine produced by the Hercules Engine Company.

Part of the Hercules DFX series, the DFXE is a naturally aspirated, direct injection,overhead valve, inline six-cylinder engine.^[1]^[2] The engine had a displacement of 855 cu in (14.011 L), with a bore of 5+5⁄8 in (143 mm), a stroke of 6 in (150 mm) and a compression ratio of 14.8:1.^[3]^[4] It developed 201 bhp (150 kW) at 1,600 rpm and a maximum 685 ft⋅lbf (929 N⋅m) of torque at 1150 rpm; 660 ft⋅lbf (890 N⋅m) at 1600 rpm.^[5]^[6]

The DFXE was designed to requirements of the British Purchasing Commission for use in the Diamond T Model 980 tank transporter. As the Diamond T Model 980 was later adopted by the US, the DFXE was one of the few diesel engines used by US tactical trucks during World War II.^[7]^[8]

The engine was used in upright or horizontal configurations.^[9]

It was used in the Diamond T Models 980 and 981 trucks in World War Two, the Le Tourneau Model B29 Tournapull earthmover (introduced in 1945),^[10] and the Oliver OC-18 crawler tractor (introduced in 1952),^[11] among others.
