Bristol Engine Co: Phoenix
Note: This is a sub-section of Bristol Engine Co
The Phoenix was a version of the Bristol Engine Co earlier Pegasus engine, adapted to run on the Diesel cycle. Only a few were built between 1928 and 1932, although samples fitted to a Westland Wapiti held the altitude record for diesel-powered planes from 1934 until World War II. The primary advantage of the Phoenix was better fuel efficiency at cruise, by up to 35%.
