Lutetia 4.C.02

From Wikipedia, the free encyclopedia
Lutetia 4.C.02
Type Air-cooled, 90° V-4 two-stroke engine
National origin France
Manufacturer Moteurs Lutetia
Designed by Marcel Echard
First run c.1950

The Lutetia 4.C.02 was a small V-4 two-stroke engine designed soon after World War II and intended to power light aircraft.

Design and development[]

Marcel Echard was an engine designer with a lifetime interest in two-strokes. His first such engine was built in 1911 and he began work on the 4.C.02 in 1949. By 1953 this engine had achieved its homologation and had been test-flown on a Jodel D.9.[1] The Briffaud GB-6 is the only known application, a one-off aircraft with a short life, though not because of its engine.[2]

Unusually for a two-stroke, the fuel/air mixture was compressed externally rather than in the crankcase.[1]
