The Willys L134 (nicknamed Go Devil) is a
Ford GPW Jeep produced during World War II. It powered nearly all the Jeep vehicles built for the U.S. and Allies.[1]
It was later used in a variety of civilian Jeep vehicles.
History
In 1940, the Willys Quad was built to compete against the Bantam reconnaissance car for evaluation by the U.S. Army.[2] The two prototype Quads were powered by the Willys “Go-Devil” engine that turned out to be the automaker's greatest asset.[2] Willys' pilot vehicle was overweight compared to the Army's requirements, but the "Go Devil" engine rated at 55 hp (41 kW; 56 PS) included a heavier transmission, a combination that proved to be beneficial in the long-run for use in cross-country travel.[3]
The engine was developed by Willys' Chief Engineer,
Quartermaster Corps called for only 85 lb⋅ft (115 N⋅m) of torque at the rear axle.[5] The extra power made it the engine of choice for the U.S. Army.[5]
The
L-head design, with valves parallel with the cylinders. Initial power output was 60 hp (45 kW; 61 PS) at 4000 rpm and 105 lb⋅ft (142 N⋅m) of torque at 2000 rpm with 6.48:1 compression.[4]
The L134 was phased out by the F-head Willys Hurricane engine beginning in 1950.
