Small Wankel Engines 680572

After stating all advantages of the new Wankel engine design, the development status of small, air cooled, rotary combustion engines from 6-20 hp is reported. These engines are now completely competitive with conventional reciprocating piston engines. The housing is cooled by air and the piston by the fuel mixture. Specific fuel consumption is comparable to that of a 4-stroke reciprocating engine of equal size. Lubrication is done by mixing oil and fuel in a ratio of 1: 50. A metering oil pump can be provided for separate tanking of fuel and oil. Some typical applications are specified.
