1816 – Robert Stirling invented his hot air Stirling engine, and what we now call a "regenerator". [5] [6] 1821 – Michael Faraday builds an electricity-powered motor. 1824 – Nicolas Léonard Sadi Carnot first publishes that the efficiency of a heat engine depends on the temperature difference between an engine and its environment.
The engine was a single-cylinder unit that displaced 6.1 dm 3, and was rated 3 PS (2,206 W) at 180/min, with a fuel consumption of 0.95 m 3 /PSh (1.29 m 3 /kWh). [ 17 ] : p43-44 Wilhelm Maybach later improved the engine by changing the connecting rod and piston design from trunk to crosshead , so it could be put into series production.
A 5-cylinder engine would thus use a "2" and a "3", whereas a 6-cylinder engine could have either 3 "2"s or 2 "3"s. Boat engines had a cast iron crankcase, whereas (in the interest of lightness) road vehicles would have an aluminium alloy crankcase. Any boat engine with an alloy crankcase would be a marinised road engine. The Gardner engine of X24
A number of Hornsby-built steam engines and tractors are in preservation, with "The Traction Engine Register 2008" listing 12 portable engines and 3 traction engines in the UK. [11] One example – no. 1851 built in August 1871 – is in the Science Museum's store at Wroughton, with another (example no. 7297) at the Museum of Lincolnshire Life ...
Prior to this time the commercial engines available had been the Lenoir engine from 1860, a non-compression engine which worked on a double-acting two-stroke cycle, but spent half of each stroke drawing gas into the cylinder. The Hugon engine was a slightly improved version, but both were quite inefficient (95 and 85 cubic feet of gas per HP ...
The petroleum engine in these tests was made by the "New York and New Jersey Ready Motor Company". This is followed by a similar analysis of Simon's engine which was an adaptation of the Brayton engine made by Louis Simon & Sons, in Nottingham, UK and marketed as The Eclipse Silent Gas Engine. The Simon engine had an added complexity in that it ...

Some of the engines were intended to do a job of work rather than for the entertainment of a model engineer, for example, the 1935 Sandhurst horizontal 2/3 bhp engine, which was described thus: [18] 'This engine will run on gas or petrol and is designed for continuous work such as dynamo, workshop or pump driving. It is supplied only as ...
