Minié 4.D

Production of the Minié 4.D series of air-cooled, flat four engines began before World War II and resumed afterwards into the 1950s.

Design and development
Établissements Victor Minié, based in Colombes, only built low power flat-four aircraft engines, always using light alloy castings. Their first three known types, the 1500 cc 4 B0 Horus, 1980 cc 4 E0 Horus and 2176 cc 4 E2 Horus, produced only 35 hp, 46 hp and 51 hp respectively. The 4 B0 was available with either single or dual ignition but all others had dual ignition.

The 4.D series, also dual ignition engines, were larger and more powerful. Production began in 1938. Halted by the Occupation of France during World War II, it began again in 1946, continuing until the company closed in 1954. Apart from the D4 Horus, all post-war engines had separate head and cylinder castings rather than the pre-war pairs.

The name Horus was used with all Minié's engines from the mid-1930s until 1949.
