The Villiers Marvil is an air cooled two-cycle engine. It was introduced in 1933 and derived its name from the first three letters of the founder’s name MAR(ston) and the first three letters of the company name VIL(liers). It is a small power unit with a bore and stroke measuring 2in by 1.1/2in and developed its rated 0.6bhp at 1,750rpm. At the outset, starting was achieved by a spring return strap starter. Later, a foot pedal and hand lever starting was offered.
One of the more notable uses of the Marvil engine was on the Pygmylite generating unit, which weighed just 56lb. Coupled to a CAV three-brush shunt wound generator, the Pygmylite unit was designed for battery charging and/or illuminating a small number of low power lamps. Other uses for this engine have been powering hedge-trimmers and pumping water.
Aound 1935, Villiers supplied a number of Pygmylite units to the Associated Manufacturers Company (London) Limited, who then marketed them under the Amanco name.
