These engine baffles are made using .025 aluminum sheet and
1/8" x 3" silicone baffle material. The baffle material is secured to the aluminum sheet using 1/8" pop rivets and an
aluminum strip 1/16" x 3/4" as a backing. The purpose of the baffle on top of the engine is to force air
entering from the cowl inlets upwards and then down through the cylinder fins for optimum cooling. The front of
the engine will also be closed off to keep the cooling air
close to the cylinders. There will also be
another sloping piece attached to the front baffle top to the bottom
of the cowl inlet to force the air upwards and over the cylinders.
The cooling air will then pass through the cylinder fins
and escape the cowl at the bottom
rear. |
