Hoffar Aero Engines

Hoffar Aero Engines was a manufacturer of aircraft engines and other components in British Columbia between 1923 and 1948. It exists today as Hoffar Aero, the BC division of BAE Systems.

History
Vancouver-based Hoffar-Beeching Shipyards got into the aero engine business in 1923, quickly establishing a division, Hoffar Aero Engines, to specialise in the manufacture and development of aircraft engines.

Harpy
Introduced in 1923, the HV-8A Harpy was HAE's first engine, a derivative of Hoffar's HV-8 Haro marine engine for use on aeroplanes; the HV-8 Haro was in turn based on Liberty L-12 components. It was an upright, water-cooled V-8.

Hobby and Hawkmoth series
Based on the HV-8A, the HIV-8A Hobby of 1924 was an air-cooled inverted V-8 using cylinders derived from Allison's reduced-bore 1A-1650, which was an air-cooled inverted V-12. It spawned two derivatives, the 4-cylinder HIL-4A Hawkmoth-4 of 1925, and the 6-cylinder HIL-6A Hawkmoth-6 of 1926; both of these were upright inline engines.
