The Train 2T, 4T and 6T were low power piston engines for light aircraft, produced in France. They were inverted, air-cooled in-line engines with the same bore and stroke, differing chiefly in the number of cylinders.

Design and development

In the 1930s Train introduced a series of air-cooled, inverted in-line piston engines for light aircraft. The T series all used the same cylinders, pistons, connecting rods, valve trains and ignition system, combined into 2 (2T), 4 (4T), and 6 (6T) cylinder units of the same layout. The number of crankshaft bearings (3, 5 or 7) and throws (2, 4 or 6) naturally depended on the number of cylinders, as did the number of cams (4, 8 or 12) on the underhead camshaft. Each cylinder had a swept volume of 0.5 L (30.5 cu in), so the displacements were 1 L (61.0 cu in), 2 L (122.0 cu in) and 3 L (183.1 cu in) and the rated outputs 15 kW (20.1 hp), 30 kW (40.2 hp) and 44.7 kW (60 hp) respectively. The Train 6D was a variant of the 6T with increased bore of 85 mm (3.3 in).[1]

Operational history

Several International 2-litre Class records were set in 1937 by aircraft powered by the Train 4T. On 7 June 1937 M. Duverene averaged 154.5 km/h (96.0 mph; 83.4 kn) over 1,000 km (621.4 mi; 540.0 nmi) and 95 km/h (59.0 mph; 51.3 kn) over 1,000 km (621.4 mi; 540.0 nmi) in a single engine Kellner-Béchereau E.1. On 27 December 1937 Mme Lafargue reached an altitude of 4,935 m (16,191 ft) in a Touya, setting both a class and a women's record.[1]

It also powered aircraft on some notable cross-country flights; on 30 December 1937 M. Lenee flew a Kellner-Béchereau E.1 from Elde to Biarritz, a distance of 1,229 km (763.7 mi; 663.6 nmi); the same day M. Blazy flew a two-seat SFAN 5 aircraft from Guyancourt to Champniers, Charente, covering 330 km (205.1 mi; 178.2 nmi).[1]

Six Train 4Ts were used in the 2 seat, 18 m (59.1 ft) span Potez-CAMS 160 flying boat, a 1:2.6 scale model of the large Potez-CAMS 161 aircraft.[2]
