Antarctic Snow-sled
The engine developed for the Grose Monoplane was also tested in Norway in 1909 as a snow-sled engine by Antarctic explorer Captain Robert Scott. The engine was changed to an in-line four-cylinder 16 horsepower (12 kW) unit with mechanical inlet valves, rather than their usual automatic valves. It used a Brown & Barlow carburettor and had a Bosch magneto ignition. The motorised sledge engine was designed to run for 300 miles (480 km) carrying three quarters of a ton at a top speed of just 3 miles per hour (4.8 km/h). In the coverage of Scott's departure on 1 June 1910 The New York Times quoted him as saying they would take the motorised sledges as far as they could and hoped they would "relieve the ponies and dogs of weight and increase the safety of the return journey".
