Aviation engines built at the “Labor” car factory in Neuilly.

-Particularly applied to the Bleriot and Hanriot planes among others and during a certain time.

-In 1911, Labor participated with a four-cylinder in the Reims Military Contest of that year, on a Savary biplane.

“Labor engine cross-section”

-It had two camshafts and combustion chambers in "T", Claudel carburetor, magneto ignition and water cooling.

“Side view of the Labor engine”

-A recently located unpublished exhaust side view, in which we can see the the water pump drag, which in turn drives the magneto.

-We also can see the lubrication tubes that go to each cylinder wall. The engine gave 70 CV.

-In the rear view we see the uncovered distribution gears and above it there are the grease pumps as a whole with their different outputs.

-On the right there is a control that alternately drives a greasing piston.

-The best known engines were those with a power of 42 CV (90 x 150 mm cylinder size) at 1,300 rpm.

-And the those with 73 CV at 1,350 rpm (100 x 120 mm).

-The perpendicular axis of the cylinders was misaligned 10° in reference with the crankshaft. Called "desaxe engine"

-As we see, the distribution was uncovered.
